Why won’t this section stay contained when I change my browser screen size? HTML, CSS

Why won’t this section stay contained when I change my browser screen size? I used HTML and CSS. It looks fine when I made my screen full size but then if I make my browser smaller it doesn’t show the full content. (it only shows half of the image but shows the full text) screenshot of how it looks on smaller browser](https://i.stack.imgur.com/i9qiK.jpg)

Change the height width of img tags.
Use % parameters
for example
height=50%
width=60%.
I think 🤔 you need also change the height width of other container tags
If design is not look like good

You should add to all importan containers`
.container
{
width:100%:
height: auto;
margin: auto;
}
//Also can try
.container
{
width: auto;
padding: 0;
}
that should work...

Problem
img has specific width and height, hence it overflows even though its container (in your case .item-img has width:50%;).
Answer
Give the img of width: 100%; and object-fit: contain or object-fit: cover if you want it cropped.

Horizontally center a div relative to the viewport when parent is small

I have a page layout with a sidebar alongside a main-content div. Partway down the page, I have a div (parent) inside of a div (child). The child div needs to be horizontally centered relative to the screen instead of the parent.
<div class="sidebar"></div>
<div class="main-content">
<div class="parent">
<div class="child"></div>
<div class="other-stuff"></div>
</div>
</div>
<style>
.parent{
width: 100px;
}
.child{
width: 200px;
}
</style>
My first thought was using absolute positioning with something like this:
.child{
position: absolute;
margin-left: auto;
margin-right: auto;
left: 0;
right: 0;
text-align: center;
}
The problem I faced here was that I had to make up for the extra space due to the child being taken out of document flow. "Other-stuff" wanted to move up to fill the gap left behind.
Is there a better way to accomplish this beyond just pushing the div around with absolute positioning and adding extra margin/padding to make up the space so the lower content doesn't come up?
I'm open to abandoning absolute positioning — that was just the first thing that came to mind.

You can use a flexbox to position multiple items in one container and knock the children out of the parent div so it's not affected by whatever positioning you do with that.

how do I vertically center content inside a div? [duplicate]

I want to center a div vertically with CSS. I don't want tables or JavaScript, but only pure CSS. I found some solutions, but all of them are missing Internet Explorer 6 support.
<body>
<div>Div to be aligned vertically</div>
</body>
How can I center a div vertically in all major browsers, including Internet Explorer 6?

Below is the best all-around solution I could build to vertically and horizontally center a fixed-width, flexible height content box. It was tested and worked for recent versions of Firefox, Opera, Chrome, and Safari.
.outer {
display: table;
position: absolute;
top: 0;
left: 0;
height: 100%;
width: 100%;
}
.middle {
display: table-cell;
vertical-align: middle;
}
.inner {
margin-left: auto;
margin-right: auto;
width: 400px;
/* Whatever width you want */
}
<div class="outer">
<div class="middle">
<div class="inner">
<h1>The Content</h1>
<p>Once upon a midnight dreary...</p>
</div>
</div>
</div>
View A Working Example With Dynamic Content
I built in some dynamic content to test the flexibility and would love to know if anyone sees any problems with it. It should work well for centered overlays also -- lightbox, pop-up, etc.

The simplest way would be the following three lines of CSS:
1) position: relative;
2) top: 50%;
3) transform: translateY(-50%);
Following is an example:
div.outer-div {
height: 170px;
width: 300px;
background-color: lightgray;
}
div.middle-div {
position: relative;
top: 50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
transform: translateY(-50%);
}
<div class='outer-div'>
<div class='middle-div'>
Test text
</div>
</div>

One more I can't see on the list:
.Center-Container {
position: relative;
height: 100%;
}
.Absolute-Center {
width: 50%;
height: 50%;
overflow: auto;
margin: auto;
position: absolute;
top: 0; left: 0; bottom: 0; right: 0;
border: solid black;
}
Cross-browser (including Internet Explorer 8 - Internet Explorer 10 without hacks!)
Responsive with percentages and min-/max-
Centered regardless of padding (without box-sizing!)
height must be declared (see Variable Height)
Recommended setting overflow: auto to prevent content spillover (see Overflow)
Source: Absolute Horizontal And Vertical Centering In CSS

Now the Flexbox solution is a very easy way for modern browsers, so I recommend this for you:
.container {
display: flex;
align-items: center;
justify-content: center;
height: 100%;
background: green;
}
body,
html {
height: 100%;
}
<div class="container">
<div>Div to be aligned vertically</div>
</div>

Actually, you need two div's for vertical centering. The div containing the content must have a width and height.
#container {
position: absolute;
top: 50%;
margin-top: -200px;
/* Half of #content height */
left: 0;
width: 100%;
}
#content {
width: 624px;
margin-left: auto;
margin-right: auto;
height: 395px;
border: 1px solid #000000;
}
<div id="container">
<div id="content">
<h1>Centered div</h1>
</div>
</div>
Here is the result.

Edit 2020: only use this if you need to support old browsers like Internet Explorer 8 (which you should refuse to do 😉). If not, use Flexbox.
This is the simplest method I found and I use it all the time
(jsFiddle demo here).

</div>
Support starts with Internet Explorer 8.

After a lot of research I finally found the ultimate solution. It works even for floated elements. View Source
.element {
position: relative;
top: 50%;
transform: translateY(-50%); /* or try 50% */
}

Use the CSS Flexbox align-items property to achieve this.
html, body {
height: 100%;
}
body {
display: flex;
align-items: center;
}
<div>This is centered vertically</div>

To center the div on a page, check the fiddle link.
#vh {
margin: auto;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
.box{
border-radius: 15px;
box-shadow: 0 0 8px rgba(0, 0, 0, 0.4);
padding: 25px;
width: 100px;
height: 100px;
background: white;
}
<div id="vh" class="box">Div to be aligned vertically</div>
Another option is to use flex box, check the fiddle link.
.vh {
background-color: #ddd;
height: 400px;
align-items: center;
display: flex;
}
.vh > div {
width: 100%;
text-align: center;
vertical-align: middle;
}
<div class="vh">
<div>Div to be aligned vertically</div>
</div>
Another option is to use a CSS 3 transform:
#vh {
position: absolute;
top: 50%;
left: 50%;
/*transform: translateX(-50%) translateY(-50%);*/
transform: translate(-50%, -50%);
}
.box{
border-radius: 15px;
box-shadow: 0 0 8px rgba(0, 0, 0, 0.4);
padding: 25px;
width: 100px;
height: 100px;
background: white;
}
<div id="vh" class="box">Div to be aligned vertically</div>

The easiest solution is below:
.outer-div{
width: 100%;
height: 200px;
display: flex;
border:1px solid #000;
}
.inner-div{
margin: auto;
text-align: center;
border: 1px solid red;
}
<div class="outer-div">
<div class="inner-div">
Hey there!
</div>
</div>

There are multiple ways to achieve this.
Using flex property of CSS.
Solution #1
.parent {
width: 400px;
height:200px;
background: blue;
display: flex;
align-items: center;
justify-content:center;
}
.child {
width: 75px;
height: 75px;
background: yellow;
}
<div class="parent">
<div class="child"></div>
</div>
or by using display: flex; and margin: auto;
Solution #2
.parent {
width: 400px;
height:200px;
background: blue;
display: flex;
}
.child {
width: 75px;
height: 75px;
background: yellow;
margin:auto;
}
<div class="parent">
<div class="child"></div>
</div>
show text center
Solution #3
.parent {
width: 400px;
height: 200px;
background: yellow;
display: flex;
align-items: center;
justify-content:center;
}
<div class="parent">Center</div>
Using percentage(%) height and width.
Solution #4
.parent {
position: absolute;
height:100%;
width:100%;
background: blue;
display: flex;
align-items: center;
justify-content:center;
}
.child {
width: 75px;
height: 75px;
background: yellow;
}
<div class="parent">
<div class="child"></div>
</div>

Unfortunately — but not surprisingly — the solution is more complicated than one would wish it to be. Also unfortunately, you'll need to use additional divs around the div you want vertically centered.
For standards-compliant browsers like Mozilla, Opera, Safari, etc. you need to set the outer div to be displayed as a table and the inner div to be displayed as a table-cell — which can then be vertically centered. For Internet Explorer, you need to position the inner div absolutely within the outer div and then specify the top as 50%. The following pages explain this technique well and provide some code samples too:
Vertical Centering in CSS
Vertical Centering in CSS with Unknown Height (Internet Explorer 7 compatible) (Archived article courtesy of the Wayback Machine)
There is also a technique to do the vertical centering using JavaScript. Vertical alignment of content with JavaScript & CSS demonstrates it.

If someone cares for Internet Explorer 10 (and later) only, use Flexbox:
.parent {
width: 500px;
height: 500px;
background: yellow;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
-webkit-justify-content: center;
-ms-flex-pack: center;
justify-content: center;
-webkit-align-items: center;
-ms-flex-align: center;
align-items: center;
}
.centered {
width: 100px;
height: 100px;
background: blue;
}
<div class="parent">
<div class="centered"></div>
</div>
Flexbox support: http://caniuse.com/flexbox

A modern way to center an element vertically would be to use flexbox.
You need a parent to decide the height and a child to center.
The example below will center a div to the center within your browser. What's important (in my example) is to set height: 100% to body and html and then min-height: 100% to your container.
body, html {
background: #F5F5F5;
box-sizing: border-box;
height: 100%;
margin: 0;
}
#center_container {
align-items: center;
display: flex;
min-height: 100%;
}
#center {
background: white;
margin: 0 auto;
padding: 10px;
text-align: center;
width: 200px;
}
<div id='center_container'>
<div id='center'>I am center.</div>
</div>

.center {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%); /* (x, y) => position */
-ms-transform: translate(-50%, -50%); /* IE 9 */
-webkit-transform: translate(-50%, -50%); /* Chrome, Safari, Opera */
}
.vertical {
position: absolute;
top: 50%;
//left: 0;
transform: translate(0, -50%); /* (x, y) => position */
}
.horizontal {
position: absolute;
//top: 0;
left: 50%;
transform: translate(-50%, 0); /* (x, y) => position */
}
div {
padding: 1em;
background-color: grey;
color: white;
}
<body>
<div class="vertical">Vertically left</div>
<div class="horizontal">Horizontal top</div>
<div class="center">Vertically Horizontal</div>
</body>

Centering only vertically
If you don't care about Internet Explorer 6 and 7, you can use a technique that involves two containers.
The outer container:
should have display: table;
The inner container:
should have display: table-cell;
should have vertical-align: middle;
The content box:
should have display: inline-block;
You can add any content you want to the content box without caring about its width or height!
Demo:
body {
margin: 0;
}
.outer-container {
position: absolute;
display: table;
width: 100%; /* This could be ANY width */
height: 100%; /* This could be ANY height */
background: #ccc;
}
.inner-container {
display: table-cell;
vertical-align: middle;
}
.centered-content {
display: inline-block;
background: #fff;
padding: 20px;
border: 1px solid #000;
}
<div class="outer-container">
<div class="inner-container">
<div class="centered-content">
Malcolm in the Middle
</div>
</div>
</div>

Centering horizontally and vertically
If you want to center both horizontally and vertically, you also need the following.
The inner container:
should have text-align: center;
The content box:
should re-adjust the horizontal text-alignment to for example text-align: left; or text-align: right;, unless you want text to be centered
Demo:
body {
margin: 0;
}
.outer-container {
position: absolute;
display: table;
width: 100%; /* This could be ANY width */
height: 100%; /* This could be ANY height */
background: #ccc;
}
.inner-container {
display: table-cell;
vertical-align: middle;
text-align: center;
}
.centered-content {
display: inline-block;
text-align: left;
background: #fff;
padding: 20px;
border: 1px solid #000;
}
<div class="outer-container">
<div class="inner-container">
<div class="centered-content">
Malcolm in the Middle
</div>
</div>
</div>
See also this Fiddle!

It can be done in two ways
body{
left: 50%;
top:50%;
transform: translate(-50%, -50%);
height: 100%;
width: 100%;
}
OR
Using flex
body {
height:100%
width:100%
display: flex;
justify-content: center;
align-items: center;
}
align-items:center; makes the content vertically center
justify-content: center;makes the content horizontally center

This is always where I go when I have to come back to this issue.
For those who don't want to make the jump:
Specify the parent container as position:relative or position:absolute.
Specify a fixed height on the child container.
Set position:absolute and top:50% on the child container to move the top down to the middle of the parent.
Set margin-top:-yy where yy is half the height of the child container to offset the item up.
An example of this in code:
<style type="text/css">
#myoutercontainer {position:relative}
#myinnercontainer {position:absolute; top:50%; height:10em; margin-top:-5em}
</style>
...
<div id="myoutercontainer">
<div id="myinnercontainer">
<p>Hey look! I'm vertically centered!</p>
<p>How sweet is this?!</p>
</div>
</div>

I just wrote this CSS and to know more, please go through: This article with vertical align anything with just 3 lines of CSS.
.element {
position: relative;
top: 50%;
transform: perspective(1px) translateY(-50%);
}

For newcomers, please try:
display: flex;
align-items: center;
justify-content: center;

The three lines of code using transform works practically on modern browsers and Internet Explorer:
.element{
position: relative;
top: 50%;
transform: translateY(-50%);
-moz-transform: translateY(-50%);
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
}
I am adding this answer since I found some incompleteness in the previous version of this answer (and Stack Overflow won't allow me to simply comment).
'position' relative messes up the styling if the current div is in the body and has no container div. However 'fixed' seems to work, but it obviously fixes the content in the center of the viewport
Also I used this styling for centering some overlay divs and found that in Mozilla all elements inside this transformed div had lost their bottom borders. Possibly a rendering issue. But adding just the minimal padding to some of them rendered it correctly. Chrome and Internet Explorer (surprisingly) rendered the boxes without any need for padding

CSS Grid
body, html { margin: 0; }
body {
display: grid;
min-height: 100vh;
align-items: center;
}
<div>Div to be aligned vertically</div>

.center{
display: grid;
place-items: center;
}

The answer from Billbad only works with a fixed width of the .inner div.
This solution works for a dynamic width by adding the attribute text-align: center to the .outer div.
.outer {
position: absolute;
display: table;
width: 100%;
height: 100%;
text-align: center;
}
.middle {
display: table-cell;
vertical-align: middle;
}
.inner {
text-align: center;
display: inline-block;
width: auto;
}
<div class="outer">
<div class="middle">
<div class="inner">
Content
</div>
</div>
</div>

Just do it: Add the class at your div:
.modal {
margin: auto;
position: absolute;
top: 0;
right: 0;
left: 0;
bottom: 0;
height: 240px;
}
And read this article for an explanation. Note: Height is necessary.

I did it with this (change width, height, margin-top and margin-left accordingly):
.wrapper {
width: 960px;
height: 590px;
position: absolute;
top: 50%;
left: 50%;
margin-top: -295px;
margin-left: -480px;
}
<div class="wrapper"> -- Content -- </div>

Not answering for browser compatibility but to also mention the new Grid and the not so new Flexbox feature.
Grid
From: Mozilla - Grid Documentation - Align Div Vertically

}
.item1 {

justify-content: center;

I think a solid solution for all browsers without using Flexbox - "align-items: center;" is a combination of display: table and vertical-align: middle;.
CSS
.vertically-center
{
display: table;
width: 100%; /* Optional */
height: 100%; /* Optional */
}
.vertically-center > div
{
display: table-cell;
vertical-align: middle;
}
HTML
<div class="vertically-center">
<div>
<div style="border: 1px solid black;">some text</div>
</div>
</div>
‣Demo: https://jsfiddle.net/6m640rpp/

Especially for parent divs with relative (unknown) height, the centering in the unknown solution works great for me. There are some really nice code examples in the article.
It was tested in Chrome, Firefox, Opera, and Internet Explorer.
/* This parent can be any width and height */
.block {
text-align: center;
}
/* The ghost, nudged to maintain perfect centering */
.block:before {
content: '';
display: inline-block;
height: 100%;
vertical-align: middle;
margin-right: -0.25em; /* Adjusts for spacing */
}
/* The element to be centered, can
also be of any width and height */
.centered {
display: inline-block;
vertical-align: middle;
width: 300px;
}
<div style="width: 400px; height: 200px;">
<div class="block" style="height: 90%; width: 100%">
<div class="centered">
<h1>Some text</h1>
<p>Any other text..."</p>
</div>
</div>
</div>

There is a trick I found out recently: You need to use top 50%, and then you do a translateY(-50%).
.outer-div {
position: relative;
height: 150px;
width: 150px;
background-color: red;
}
.centered-div {
position: absolute;
top: 50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
transform: translateY(-50%);
background-color: white;
}
<div class='outer-div'>
<div class='centered-div'>
Test text
</div>
</div>

How to position text and Div on top of eachother and align them in center?

So I can't figure this out.
I'm trying to get a red vertical box to display in middle of page. I've set the div's margin to auto.
And then there's another div that holds a centered text.
Setting margin auto on both.
They are both stacking on top of eachother fine in middle of page.
However I want it to be responsive to all heights. Right now it's just responsive to the x-axis and not the height.
HTML & CSS:
.parentDiv {
position: relative;
width: 250px;
height: 450px;
margin: auto;
}
#RedBox {
width: 250px;
height: 450px;
background-color: #FF0000;
margin: auto;
}
#CSText {
position: absolute;
top: 45%;
width: 250px;
color: black;
text-align: center;
}
<div class="parentDiv" style="margin-top: auto;">
<div id="CSText" class="TextAlignCenter">
</div>
<div id="RedBox">
</div>
</div>

flexbox would be a great solution to this:
.container {
height: 100vh;

HTML
<div class="parentDiv">
<div class="inner">
<div id="RedBox">

CSS
.parentDiv {
display:table;
width: 100%;
height: 100%;
position: absolute;

Keep distance between 2 out of 3 elements equal when scaling window (responsive)

There are 2 img div's on top of each-other, next to a fluid header logo (.svg) also in a div.
The HTML:
<header class="site-header" role="banner" itemscope="itemscope" itemtype="http://schema.org/WPHeader"><div class="wrap"><div id="menu_container"><img src="http://95.85.63.245/wp-content/uploads/dynamik-gen/theme/images/Hamburger_optimized.svg" alt="menu" class="menu-btn" /><div class="menu_spacer"></div><img src="http://95.85.63.245/wp-content/uploads/dynamik-gen/theme/images/searchicon.png" alt="zoek" class="search_icon" /></div>
<div class="title-area"><h1 class="site-title" itemprop="headline"></h1></div><div class="vr_menu_logo"><img src="http://95.85.63.245/wp-content/uploads/dynamik-gen/theme/images/logo_VR_font.svg"></div>
</div></header>
The CSS:
.vr_menu_logo{
max-width:95%;
float:left;
margin-right:20px;
}
#menu_container {
max-width: 5%;
float: right;
}
.menu-btn{
cursor: pointer;
max-height: 30px;
max-width: 30px;
margin-top:2em;
}
.menu_spacer{height:4em;}
.search_icon{
cursor: pointer;
max-height: 24px;
max-width: 24px;
}
.site-header .wrap {
width: 1260px;
}
.site-header .wrap {
margin: 0 auto;
padding: 0;
float: none;
overflow: hidden;
}
Goal:
Scaling the browser window would keep the small hamburger and the search icon's on level with respectively the top and bottom of the logo. Actually the 3 seperate items should act as one logo.

I was hoping a spacer div with a max-height would do the trick, or display:table-cell;
But I can't get it to work, anyone have an idea? (javascript can be an option too, but this must be possible with CSS I would think...)

here is an example using flexbox - note in the fiddle that the two div are exactly the same apart from having a different height. This should help you getting what you are trying to achieve. Obviously check what kind of browser support you need to provide as flexbox is a relatively new technology.
