There are two containers. One of which is the main (essentially, the parent) container. Another is a child container that serves as a tag for categorizing the content. The tag container needs to be positioned at the top right corner of the main content container, pushed over a bit from the right and where the top border of the main container splits the tag container in half. Below, I have been able to more or less do so. But my question is how can I ensure that the top border of the main container perfectly coincides with the center of the tag container?
Including a link to the codesandbox for convenience.
<div className="main">
<div className="tag">TAG</div>
<p>MAIN CONTENT</p>
</div>
.main {
height: 150px;
width: 350px;
border: 1px solid black;
border-radius: 16px;
display: flex;
justify-content: center;
align-items: center;
position: relative;
}
.tag {
height: 20px;
width: 100px;
border: 1px solid green;
border-radius: 8px;
position: absolute;
top: -12px;
right: 24px;
z-index: 999;
background-color: green;
}
When you have a div with position: relative explicitly, then other divs inside it will be relative to it.
By applying position: absolute to the child div you will produce that it will be at the position (0, 0) of the parent container (counting from top-left). Then, if you apply top: height/2 to your child container, you will assure that it will always be centered with the top border of your parent container. Check the snippet below.
.container {
margin-top: 40px;
}
.parent {
height: 200px;
width: 320px;
background-color: orange;
position: relative;
}
.child {
height: 40px;
width: 80px;
position: absolute;
background-color: red;
top: -20px; /* must the half of the height.*/
right: 10%;
}
<div class="container">
<div class="parent">
<div class="child"></div>
</div>
</div>
Hope it helps you.

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.
*,
*::before,
*::after {
margin: 0;
padding: 0;
box-sizing: border-box;
}
body {
width: 100vw;
}
.parent {
border: 1px solid black;
width: 100px;
height: fit-content;
}
.container {
display: flex;
flex-direction: column;
align-items: center;
width: 100%;
height: 100%;
gap: 2px;
}
.child {
display: block;
border: 1px solid black;
width: 200px;
height: fit-content;
}
.other-stuff {
display: block;
border: 1px solid black;
width: 200px;
height: fit-content;
}
<div class="sidebar"></div>
<div class="main-content">
<div class="parent">
I'm the Parent

<div class="container">
<div class="child">I'm the Child</div>
<div class="other-stuff">I'm the Other Stuff</div>

Position: sticky with bottom:10px on div with class sidebar is working as expected but with property top:10px is not working as expected?
With position: sticky with bottom: 10px on div with class sidebar, when we scroll down the div stick to view port with a bottom edge above 10px to the view port.
Similarly with position: sticky with top:10px on div with class sidebar, as we scroll up the div should stick to top with the top edge of div 10px below the viewport.
But it is not working this way, what is the problem?

/*width: 1654px;*/

In my case, the parent of the sticky element (the sidebar) had a smaller height than the content => the sticky element wasn't going down more than the sidebar's height.
The solution: I made the sidebar's height equal to the content's height (using display flex on the content's and sidebar's wrapper).
HTML:
<div clas="container">
<div class="content">This initially has a bigger height than sidebar.</div>
<div class="sidebar">
<div class="sticky"></div>
</div>
</div>
CSS:
.container { dislay: flex; } // By using this I make the sidebar the same height as the content
.sticky { position: sticky; top: 0; }
I am trying to move content left and right using on click event and need to stop by margins on the left or right. list-items generating dynamically. Here is the code I tried so far but no worth. By my code it is moving the container left and right. But I need to move list-items left and right.
How can I do this.?
function moveList(px) {
$('.list').animate({
'marginLeft': px
});
}
.list {
white-space: nowrap;
overflow: auto;
height: 85px;
padding: 10px 0;
margin: 25px 0;
position: relative;
}
.list-item {
display: inline-block;
min-width: 20%;
max-width: 150px;
padding: 10px 0;
border-radius: 3px;
background: #eee;
border: 1px solid #ddd;
margin: 0 5px;
cursor: pointer;
text-align: center;
}
#right-arrow {
width: 40px;
height: 40px;
display: block;
position: absolute;
right: 0;
top: 35px;
z-index: 999;
border-radius: 50%;
background: url(img/right-arrow.png) no-repeat #000;
}
#left-arrow {
width: 40px;
height: 40px;
display: block;
position: absolute;
left: 0;
top: 35px;
z-index: 999;
border-radius: 50%;
background: url(img/left-arrow.png) no-repeat #000;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="right-arrow" onclick="moveList('-=50px')"></div>
<div id="left-arrow" onclick="moveList('+=50px')"></div>
<div class="list">
<div class="list-item">1</div>
<div class="list-item">2</div>
<div class="list-item">3</div>
<div class="list-item">4</div>
<div class="list-item">5</div>
<div class="list-item">6</div>
<div class="list-item">7</div>
<div class="list-item">8</div>
<div class="list-item">9</div>
<div class="list-item">10</div>
</div>
Try script like this:
function moveList(px) {
$(".list-item:first-child").animate({
'marginLeft': px
});
}
It will be easier for you if you create a element that wraps the .list-items with:
position: absolute;
top: 0;
left:0;
Then, instead of modify the margin, you should modify the left value.
If you want to use semmantic content for your web it's better to use another HTML structure, not only div. For example:
<nav> <!-- As this is containing page navigation elements-->
<ol> <!-- As this is an ordered list of elements-->
<li> <!-- Each list element-->
First element
</li>
<li>
Second element
</li>
</ol>
</nav>
Simply translate them.
Define this (given that clicker is the selector for your click event).
var xValue = -5;
$("#clicker").on('click', function(e) {
e.preventDefault();
$(".list-item").css("transform","translateX("+xValue+")");
xValue -= 5;
});
Translate will not mess with your markup, and only move the objects it's working on to the left (in this case).
By keeping xValue you can keep moving them to the left by repeatedly clicking clicker.
I don't know how to explain this, but maybe in this case picture tells story instead of me:
Shortly if you cannot see it. I'm trying to place logo inside multiple areas (header, body, content) like a global image.
Is that possible with CSS, JavaScript, HTML, PHP?
And if it is, any guides or tips?
You can place your logo inside of the nav (in this case) section. The logo must be absolutely positioned, so that it doesn't mess up with other element's alignment, and your nav section must be relatively positioned, so the logo gets placed in relation to the nav container (even if it's absolute!).
You didn't provide any HTML/dimensions, so we're pretty much left to guess, but here's how it would look, picking arbitrary dimensions.
.nav {
position: relative;
height: 100px;
}
/* .logo is a child of .nav */
.logo {
position: absolute;
top: -50px;
height: 200px;
width: 200px;
left: 0;
}
Take a look:
body {
color: #fff;
text-align: center;
}
.header {
height: 100px;
background: red;
}
.nav {
position: relative;
height: 70px;
background: blue;
}
.logo {
position: absolute;
width: 200px;
height: 200px;
left: 0;
top: -50px;
}
.body {
height: 250px;
background: purple;
}
.footer {
height: 100px;
background: lightblue;
}
<div class="header"> Header </div>
<div class="nav">
<img src="http://www.udavinci.com/wp-content/uploads/2014/09/stackoverflow.png" class="logo"/>
Nav
</div>
<div class="body"> Body </div>
<div class="footer"> My Feet </div>
Alternatively, you may also place your logo outside of everything but inside of the body tag, and just use position: absolute, and tweak it's position (top, left, etc..), according to the dimensions of the relevant elements.
You can put your logo in header and position with :
.your-logo-class {
position: relative;
top: 100px; // Adjust this value
}
You could do it like this:
body { margin: 0; padding: 0; background-color: black;}
#top { background-color: red; width: 100%; height: 100px; }
#nav { background-color: blue; width: 100%; height: 50px; }
#content { background-color: green; width: 400px; height: 500px; margin: 0 auto;}
#footer { background-color: purple; width: 100%; height: 50px; }
<body>
<div id="top">
</div>
<div id="nav">
<img src="images/logo.png" style="padding: 10px;">
</div>
<div id="content">
</div>
<div id="footer">
</div>
</body>
Or you could add position: absolute; to the img style="" and then play around with the margin/padding.
Hmm, a logo is basically an <img> tag, you can place them where ever you like, just give all those <img> tags a class and style it the way you want.
i'm under this situation... i've made an overlay div working as a popup window.
Contains a little header that has some text and a "X" button to "close" it (which is a child div). Then it has the body content as another child div.
I've set the draggable and re-sizable jquery functionality to the parent overlay popup window.
Works fine... sort of speak, because when i scroll down due to large content, the little handler resize icon moves up or down depending on how I scroll instead of being fixed at the bottom like where it was in the first place.
And another thing, the little child divs inside its parent aren't resized with the parent's size. How can i achieve that?
This is my HTML code:
<div id="sendmessage-panel-overlay">
<div id="overlay-header">
<h1 id="title" style="font-size: 12px; float: left; padding-top: 7px;"></h1>
<div id="maximize_icon">
<img src="<c:url value='/images/x-icon.gif'/>" title="Close window" onclick="closePopUp()">
</div>
</div>
<div id="body-content"></div>
</div>
And this is the CSS:
#sendmessage-panel-overlay
{
background-color: white;
border-color: gray;
border-style: solid;
border-width: 1px;
float: left;
height: 500px;
left: 21%;
padding: 0px 17px 17px;
position: fixed;
text-align: center;
top: 10%;
visibility: hidden;
width: 700px;
overflow: auto;
}
#overlay-header
{
width: 700px;
position: fixed;
height: 30px;
background-color: #fff;
}
#maximize_icon {
width: 16px;
height: 16px;
float: right;
}
#body-content {
padding-top: 50px;
padding-left: 10px;
display: inline-block;
}
Either move the element outside of the scroll-able element or use position: absolute (probably combined with a position: relative somewhere).
