Make child div width 100% of container with overflow-x using Flexbox

I'm trying to make a child div of a Flexbox container with overflowing-x content have 100% of the width WITH the overflow, but I can't figure out it, have made several searches and couldn't find a solution;
Can someone help me?
Fiddle: https://codepen.io/joaovtrc/pen/MWaaxKr
HTML:
<div class="test-container">
<div class="test-item-overflow">
overflowing contenttttttt
</div>
<div class="test-item-2"></div>
</div>
CSS:
.test-container {
width: 1000px;
height: 500px;
margin: auto;
background: black;
display: flex;
flex-direction: column;
overflow-x: auto;
}
.test-item-overflow {
width: fit-content;
height: 55px;
background: red;
border: 1px solid yellow;
}
.test-item-2 {
width: 100%;
height: 55px;
background: blue;
border: 1px solid green;
}
I want the 'test-item-2' (the one with the blue background) div to match the red one in width, but, keep in mind that the content on the redbox might not be exactly the same everytime, so no calc(100% + x) with fixed params...

As you have set the width: fit-content; for the overflow div, it makes the width uncontrollable as it grows with more content in that div. one solution might be to change the width: 100%; and add overflow-x: scroll to the class .test-item-overflow. (see the change in the below snippet)
However, if you want to keep the width: fit-content; for the red div and change the blue div's width along with the red one (depending on the content) you can add: document.getElementsByClassName("test-item-2").style.width = document.getElementsByClassName("test-item-overflow").offsetWidth + "px". (in this case it's better to define id for the divs and use getElementById in the js code)
.test-container {
width: 1000px;
height: 500px;
margin: auto;
background: black;
display: flex;
flex-direction: column;
overflow-x: auto;
}
.test-item-overflow {
width: 100%;
overflow-x: scroll;
height: 55px;
background: red;
border: 1px solid yellow;
}
.test-item-2 {
width: 100%;
height: 55px;
background: blue;
border: 1px solid green;
}
<div class="test-container">
<div class="test-item-overflow">
aaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
</div>
<div class="test-item-2"></div>
</div>

So I really recommend you go ahead and add the following lines
Margin:0px;
This will take away all the space between your content and browser
Padding:0px;
This will take away all the space between your content and content border
Overflow:hidden;
Finally this should remove overflown content.
Hope that helped!

Better to use display:grid; on .test-container. After if you dont want to have gap between to the 2 cells, this is due to .test-container { height: 500px; }.
DEMO:
html body {
width: 100vw;
height: 100vh;
margin: 0px;
overflow: auto;
display: flex;
align-items: center;
background: grey;
}
.test-container {
width: 1000px;
height: 500px;
margin: auto;
background: black;
/*display: flex;
flex-direction: column;*/
display:grid;
overflow-x: auto;
}
.test-item-overflow {
width: 1500px;
height: 55px;
background: red;
border: 1px solid yellow;
}
.test-item-2 {
width: 100%;
height: 55px;
background: blue;
border: 1px solid green;
}
<div class="test-container">
<div class="test-item-overflow">
overflowing contenttttttt
</div>
<div class="test-item-2"></div>

calculating border radius for a small width with css

I want to create a slider for progress
if say it's at 1% how can I calculate the right px/% for the border-radius?
when it's a big % it looks good
<div style="background: grey; height: 25px; border-radius: 12.5px; width: 100%">
<div style="background: green; height: 25px; border-radius: 12.5px; width: 15%" />
</div>
when it's small like 1% it looks like this
<div style="background: grey; height: 25px; border-radius: 12.5px; width: 100%">
<div style="background: green; height: 25px; border-radius: 12.5px; width: 1%" />
</div>

try adding:
overflow: hidden;
for your green filler. It will hide inside the container. What you're trying to do is close to impossible. Can you imagine adding a border-radius on an element that is < 2px in width?
<div style="background: grey;
height: 25px;
border-radius: 12.5px;
width: 100%;
overflow: hidden;">
<div style="background: green;
height: 25px;
border-radius: 12.5px;
width: 1%" />
</div>

A 1% is supposed to look small in my opinion. just add overflow: hidden to your parent div, then that should look better.
<div style="overflow:hidden; background: grey; height: 25px; border-radius: 12.5px; width: 100%">
<div style="background: green; height: 25px; border-radius: 12.5px; width: 1%" />
</div>

If you would like to completely keep the radius of the progress bar, you may try cloning a same element as the progress bar container and set its left.
This example is working with Javascript or you may use pure css only by editing its left.
Please see if this is your another good choice as well.
set_progress(2); // percentage of progress
function set_progress(p) {
$('.progress-container span').css('left', (p-100)+'%');
}
.progress-container {
position: relative;
display: block;
width: 100%;
height: 24px;
background-color: #555;
border-radius: 12px;
overflow: hidden;
}
.progress-container > span {
position: absolute;
display: block;
top: 0;
left: -100%;
width: 100%;
height: 24px;
background-color: #0c0;
border-radius: 12px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="progress-container">
<span></span>
</div>

You are losing the border-radius because you are altering the width of your green progress element.
Instead, if you set the green div to the same 100% width, you can represent the progress by using CSS transform to move the green div to the left.
transform: translateX(-90%);
This is the value you want to change to update the progress, use inverse value, so -90% is really 10% of progress (100 - 10 = 90) and so on.
Use overflow: hidden; on the outer div to hide the extra green.
.progress-bar {
overflow: hidden; /* hide the green that overflows */
background: grey;
height: 25px;
width: 100%;
border-radius: 12.5px;
}
.progress {
display: block;
background: green;
height: 100%;
width: 100%; /* same width as outer div */
border-radius: 12.5px;
transform: translateX(-90%); /* this is the value you want to change to update the progress, use inverse value, so -90% is really 10% of progress (100 - 10 = 90) */
}
<div class="progress-bar">
<div class="progress"></div>

Dragscroll a div containing floated divs

I am trying to drag-scroll a div containing floated elements. You can play with it here
The intent is that dragging the grey area should drag the pane. I have applied suggestions from similar "expand div to floated content" questions. This is my best effort - vertical overflow looks good but horizontal scroll does not.
added a clear element to the end of the floated elements
added "overflow: hidden;" to parent of floated elements
tried floating the parent div but this didn't seem to fix it
Setting a fixed width works but the content is dynamic.
Code
<div class="title">Tall elements - ok</div>
<div id="wrapper">
<div id="scroller">
<div id="items">
<div class="item-tall">hi</div>
<div class="item-tall">ho</div>
<div class="item-tall">off</div>
<div class="item-tall">...</div>
<div class="clear"></div>
</div>
</div>
</div>
<div class="title">Wide elements - not ok</div>
<div id="wrapper2">
<div id="scroller2">
<div id="items2">
<div class="item-wide">hi</div>
<div class="item-wide">ho</div>
<div class="item-wide">off</div>
<div class="item-wide">...</div>
<div class="clear"></div>
</div>
</div>
</div>
$('#wrapper, #scroller').dragscrollable({
dragSelector: '#items',
acceptPropagatedEvent: false
});
$('#wrapper2, #scroller2').dragscrollable({
dragSelector: '#items2',
acceptPropagatedEvent: false
});
#wrapper {
width: 220px;
height: 200px;
overflow: auto;
border: 1px solid #ff0000;
background-color: lightgray;
cursor: all-scroll;
}
#scroller {
height: 100%;
}
#wrapper2 {
width: 220px;
height: 200px;
overflow: auto;
border: 1px solid #ff0000;
background-color: lightgray;
cursor: all-scroll;
}
#scroller2 {
height: 100%;
}
#items {
overflow: hidden;
}
#items2 {
height: 100%;
/* width: 500px; this will fix it */
overflow: hidden;
}
.item-tall {
width: 30px;
height: 500px;
float: left;
background-color: white;
cursor: default;
}
.item-wide {
height: 30px;
min-width: 1000px;
float: left;
background-color: white;
cursor: default;
}
.clear {
clear: both;
}
.title {
padding: 20px;

Horizontal scroll in a parent div containing floated child divs
Floating elements within a div, floats outside of div. Why?

So, What do you want?
Horizontal scroll bar should not appear in your second item?
For that don't assign width in the second wrapper.You have assigned width:220px;, in the second wrapper but only one child has width:300px ,i.e greater than parent width that's why the horizontal scroll bar is coming.
Don't use width for wrapper2....
#wrapper2 {
height: 200px;
overflow: auto;
border: 1px solid #ff0000;
background-color: lightgray;
cursor: all-scroll;
}
I hope this works.

separate div to 3 columns

I asked same question 2 days ago but now i still don't get it.
I have 1 div and i want it to be separate into 3 columns of div. I know how to do this for 2 column but, when i am trying 3 column(right, center and left) i get this:
Problem: The pink square is not in the center
Here is my code:
HTML:
<div id="our_services" class="container">
<h1>המוצרים שלנו</h1>
<div id="try">
<div id="product1">
</div>
<div id="product2">
</div>
<div id="product3">
</div>
</div>
</div>
CSS:
#our_services {
/*height: 450px;*/
text-align: center;
font-family: "open_sans_hebrewregular", "alefregular",arial,"Times New Roman";
color: black;
background-color: rgb(224,224,224);
overflow: auto;
margin: auto;
}
#try {
background-color: orange;
width: 50%;
height: 50%;
margin: auto;
}
#product1 {
width: 30%;
height: 75%;
background-color: green;
float: right;
margin: 5px;
}
#product2 {
width: 30%;
height: 75%;
background-color: pink;
float: right;
margin: 5px;
}
#product3 {
width: 30%;
height: 75%;
background-color: blue;
float: left;
margin: 5px;
}

Try with display:inline-block; instead.
exemple

#our_services {
/*height: 450px;*/
text-align: center;
font-family: "open_sans_hebrewregular", "alefregular", arial, "Times New Roman";
color: black;
background-color: rgb(224, 224, 224);
overflow: auto;
margin: auto;
}
#try {
background-color: orange;
width: 50%;
height: 50%;
margin: auto;
}
#product1 {
width: 30%;
height: 75%;
background-color: green;
float: left;
margin: 1.5%;
}
#product2 {
width: 30%;
height: 75%;
background-color: pink;
float: left;
margin: 1.5%;
}
#product3 {
width: 30%;
height: 75%;
background-color: blue;
float: left;
margin: 1.5%;
}
<div id="our_services" class="container">
<h1>המוצרים שלנו</h1>
<div id="try">
<div id="product1">
afs
</div>
<div id="product2">
asf
</div>
<div id="product3">
asf
</div>
</div>
</div>
You had float right as well on one of the boxes

use float left to 1st and 2nd div also. and give margin on percentage. I think this will solve your problem.

I don't know of any way you can do this purely with html/css techniques. You can arrange the items with javascript after the dom (or this part at least) has loaded.
On the other hand, this gets you a little closer to what you want, although the distances between rows won't be equal to the distances between firs/last row and beginning/end of the orange rectangle:
<div id="our_services" class="container">
<h1>המוצרים שלנו</h1>
<div id="try">
<div class="smth">
<div id="product1" class="product">
</div>
</div>
<div class="smth">
<div id="product2" class="product">
</div>
</div>
<div class="smth">
<div id="product3" class="product">
</div>
</div>
</div>
<style>
#our_services{
/*height: 450px;*/
text-align: center;
font-family:"open_sans_hebrewregular", "alefregular",arial,"Times New Roman";
color: black;
background-color: rgb(224,224,224);
overflow: auto;
margin: auto;
}
.smth {
width: 33%;
height: 75%;
float: left;
}
#try{
background-color:orange;
width:50%;
height:50%;
margin:auto;
}
.product {
width: 90%;
height: 100%;
margin: auto;
}
#product1{
background-color:green;
}
#product2{
background-color:pink;
}
#product3{
background-color:blue;
}
</style>
</div>

As far as I understand:
If you don't want any spaces between you'd have to set the width property to (100/3)%
It all depends on your layout of what you want, if you want margin spaces between them all so that they're equally spaced between each other and the edges of their container div you'll have to work out what to do there. So in the case now you have 30% width for each, that leaves you with 10% spacing width which you can spread to 2.5% for margin-left: of your first 2 divs and then for the 3rd div use 2.5% for margin-right: (for a space between the right side and the 3rd div) margin-left:
But as I said, it all depends on what exactly you want for your layout, so if this doesn't answer your question could you tell me more about your expected layout?
If you want a very simple fix based off of what you have at the moment you could set the margin: property to auto and that should center the middle div between what you have now.
Edit: You should also edit the float properties so that they all float one way.

Check the example below:
Code:
#our_services {
text-align: center;
font-family: "open_sans_hebrewregular", "alefregular", arial, "Times New Roman";
color: black;
background-color: rgb(224, 224, 224);
overflow: auto;
margin: auto;
}
#try {
background-color: orange;
width: 50%;
height: 50%;
margin: auto;
}
#product1 {
width: 31%;
height: 200px;
background-color: green;
float: left;
margin: 1%;
}
#product2 {
width: 31%;
height: 200px;
background-color: pink;
float: left;
margin: 1%;
}
#product3 {
width: 31%;
height: 200px;
background-color: blue;
float: left;
margin: 1%;
}
<div id="our_services" class="container">
<h1>המוצרים שלנו</h1>
<div id="try">
<div id="product1">
</div>
<div id="product2">
</div>
<div id="product3">
</div>
</div>
</div>
Example

add the following css:
html, body {
width: 100%;
height: 100%;
}
and add the following properties to #our_services css:
width: 100%;
height: 100%;
further set box-sizing: border-box; and margin: 0% 0% 0% 2.5%; (top as you need, right 0%, bottom as you need and left 2.5%) for the prouctu divs. Btw. you should extract common style to a product class and apply the class on the product divs...

One nice solution is to use display:table and display:table-cell. Which will works for 2 and 3 div both.
HTML:
<div id="our_services" class="container">
<h1>המוצרים שלנו</h1>
<div id="try">
<div id="product1" class="product">
</div>
<div id="product2" class="product">
</div>
<div id="product3" class="product">
</div>
CSS:
#our_services {
background-color: rgb(224, 224, 224);
color: black;
font-family: "open_sans_hebrewregular","alefregular",arial,"Times New Roman";
height: 450px;
margin: auto;
overflow: auto;
text-align: center;
}
#try {
background-color: orange;
display: table;
height: 50%;
margin: auto;
width: 50%;
border-collapse: separate;
border-spacing: 10px;
}
.product{
display: table-cell;
height: 75%;
margin: 5px;
width: 30%;
}
#product1 {
background-color: green;

Trying to center a link in CSS with the top header but wont move

Hello I am trying to keep the links centered of the tan margin. How do I get it centered to the tan margin? I've tried a few things but margins won't move.
Here is the website if you want to visually see the issue:
http://codepen.io/willc86/pen/hpFLe
I am not sure why links don't want to move when I use margin-left or margin-top
css is
#header{
background-color: tan;
width: 90%;
Height: 80px;
margin: auto;
margin-bottom: 30px;
text-align: center;
}
#header a {
margin: 40px;
border: 3px solid green;
}
#box{
border: 3px solid red;
}
#space{
text-align: center;
}
#leftcolumn {
width: 300px; border: 1px solid red; float: left; margin-left: 30px;
}
#mcolumn {
width: 300px; border: 1px solid red; margin: auto;
}
#rightcolumn {
width: 300px; border: 1px solid red; float: right; margin-right: 30px;
}
.clear {
clear: both;
}
#box2{
border: 3px solid green;
margin: 40px;
text-align: center;
}
#bx{
border: 3px solid green;
margin: auto;
width: 200px;
}
#box2{
border: 3px solid green;
margin: 40px;
text-align: center;
}
#margin{
margin: 30px;
}
and my html is
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<div id="header">
Facebook
Google
Yahoo
</div>
<div id="box">
<div id="space">
<div id="leftcolumn"><p>LEFT</p></div>
<div id="rightcolumn"><p>RIGHT</p></div>
<div id="margin">
<div id="mcolumn"><p>mcolomn</p></div>
</div>
<div class="clear"></div>
</div>
</div>
<div id="box2">
<div id="margin">
<div id="bx">
<p> hello what is up
</div>
</div>
</div>
</body>
</html>

Add this to #header
#header {
....
line-height: 80px;
vertical-align: middle;
}
Also check the demo.
Note that this might give trouble if you want to lines of menu.

General tip : always add line-height equal to div's height to align your link in vertical middle position
line-height:80px; in #header a would do the job for you! :)

If you want to align the links vertically:
#header a {
...
line-height: 80px;
}

#header a {
border: 3px solid #008000;
display: inline-block;
margin: 0 40px;
position: relative;
top: 50%;
}
Note: the top: 50% somehow uses height and margin of parent.

You can also do it like this: create a div inside (I've called it links) which you can format away from your other div. The margins don't show because the text is inline, and you can't give inline text a top and bottom margin. Changing it to display: inline-block and position: relative allows you to change the place of the div (if you don't want to set line height). Top: 36% will centre it because this counts the margin (so you want half of 80/110 px, or 4/11 = ~36% (you can make this 50% by adding the margin to the object beneath).
HTML:
<div id="links"> Facebook
Google
Yahoo
</div>
CSS:
#header a {
border: 3px solid green;
margin-left: 40px;
margin-right: 40px;
}
#links {
display: inline-block;
position: relative;
top: 36%;
}
