Content height is not automatically adjusted when scrolling - html

I am trying to create a modal that has a footer and an header. The content has two columns: LeftSection and RightSection. I want to have the second column fill the height of the content depending on what the first columns height is (which can differ based on content). From the snippet, this means to have the black div go down as much as the red one does.
.Container {
margin: auto auto;
width: 80vw;
height: 250px;
background-color: #8080801a;
flex: 1;
display: flex;
flex-direction: column;
}
.Header {
height: 50px;
width: 100%;
background-color: #61dafb;
}
.FlexContainer {
flex: 1;
display: flex;
overflow: auto;
}
.LeftSection {
width: 200px;
height: 400px;
background: red;
}
.RightSection {
width: 100%;
background-color: black;
}
.Footer {
height: 50px;
background-color: blue;
width: 100%;
}
<div class="Container">
<div class="Header"></div>
<div class="FlexContainer">
<div class="LeftSection" ></div>
<div class='RightSection' ></div>
</div>
<div class='Footer' />
</div>

Do you want this?
.Container {
margin: auto auto;
width: 80vw;
height: 250px;
background-color: #8080801a;
flex: 1;
display: flex;
flex-direction: column;
}
.Header {
height: 50px;
width: 100%;
background-color: #61dafb;
}
.FlexContainer {
flex: 1;
display: flex;
overflow: auto;
}
.LeftSection {
width: 200px;
height: 400px;
background: red;
position: sticky;
top: 0;
}
.RightSection {
width: 100%;
background-color: black;
position: sticky;
top: 0;
}
.Footer {
height: 50px;
background-color: blue;
width: 100%;
}
<div class="Container">
<div class="Header"></div>
<div class="FlexContainer">
<div class="LeftSection" ></div>
<div class='RightSection' ></div>
</div>
<div class='Footer' />

Image not taking parent height

I have following html:
<div class='fullHeight'>
<div class='flexbox'>
<div class='first'>
<p>foo</p>
</div>
<div class='second'>
<p>bar</p>
<img src='http://www.mandysam.com/img/random.jpg'>
</div>
</div>
</div>
and css:
* {
box-sizing: border-box;
margin: 0;
padding: 0;
}
.fullHeight {
height: 100vh;
background-color: red;
}
.flexbox {
display: flex;
flex-direction: column;
height: 100%;
maxHeight: 100%;
width: 100%;
background-color: green;
}
.first {
background-color: magenta;
}
.second {
background-color: yellow;
flex: 1 1 auto;
max-height: 100%;
height: 100%;
widht: auto;
}
As long there is no image, everything works fine:
But as soon as a picture comes in, it overflows the container, instead of being shrinked to fit available height:
Codepen
You missed
display: flex;
flex-direction: column;
in your .second class, that's why the flex property isn't doing anything. Also it should be max-height instead of maxHeight and width instead of widht.
You can use background-image for your purpose.
* {
box-sizing: border-box;
margin: 0;
padding: 0;
}
.fullHeight {
height: 100vh;
background-color: red;
}
.flexbox {
display: flex;
flex-direction: column;
height: 100%;
width: 100%;
background-color: green;
}
.first {
background-color: magenta;
}
.second {
background-color: yellow;
display: flex;
flex-grow: 1;
flex-direction: column;
}
.container {
background-color: green;
flex-grow: 1;
background-image: url('http://www.mandysam.com/img/random.jpg');
background-size: contain;
background-repeat: no-repeat;
}
<div class='fullHeight'>
<div class='flexbox'>
<div class='first'>
<p>foo</p>
</div>
<div class='second'>
<p>bar</p>
<div class="container">
</div>
</div>
</div>
</div>
Add height and width properties to your image. Or just height. Maybe also object-fit: cover;
.second img {
height: 100%;
width: 100%;
object-fit: cover;
}
Using positions is the other solution but it's very risky and it depends on your plan for future code in this project!!
.second {
background-color: yellow;
flex: 1 1 auto;
max-height: 100%;
height: 100%;
widht: auto;
position:relative
}
.second img{
height: 95%;
width: 100%;
position:absolute;
bottom:0;
right:0;
}

CSS overlay scrolling issues

I posted a question here that was answered and worked for me at the time. I had to re-write my code with flex box and now the overlay scrolling doesn't work. I tried adding position:sticky; to the behind div that fixed it in the first question I posted, but doesn't work for my current code. Using my current code, how can I get the overlay scrolling to work again? What am I missing?
Edit:
using only css and html, is it possible to scroll away the front div (overlay div ontop of the image) completely before scrolling down the rest of the page? Essentially, wondering if overlay scrolling while freezing the behind div is possible in only css? Then once the front div is gone, unfreeze the background scrolling and continue on. Similar to this site here: https://humaan.com/ .

just add to element you want to be scrollable an overflow: auto;
e.g :
#right {
overflow: auto;
}

Dispay flex row and uniformed sizes

I would like all my element to have the same height and the separator to cover all the height. How can I achieve that please ?
The separator is pink, you can see it here with a height: 5em
.daddy {
height: 10em;
width: 10em;
}
.container {
width: auto;
height: auto;
display: flex;
flex-direction: row;
align-items: flex-start;
justify-content: center;
border: 1px solid lightgrey;
}
.child1 {
width: 3em;
height: 10em;
background-color: red;
}
.child2 {
width: 3em;
height: 15em;
background-color: blue;
}
.separator {
width: 10px;
height: 5em;
background-color: pink;
}
<div class="daddy">
<div class="container">
<div class="child1"></div>
<div class="separator"></div>
<div class="child2"></div>
</div>
</div>
If you remove the align items from container, all three columns will grow to fill the row
.daddy {
height: 10em;
width: 10em;
}
.container {
width: auto;
height: auto;
display: flex;
flex-direction: row;
border: 1px solid lightgrey;
justify-content:center;
}
.child1 {
width: 3em;
background-color: red;
height: 10em; /* this is just to give it some height as no column currently has any height */
}
.child2 {
width: 3em;
background-color: blue;
}
.separator {
width: 10px;
background-color: pink;
}
<div class="daddy">
<div class="container">
<div class="child1">
</div>
<div class="separator">
</div>
<div class="child2">
</div>
</div>
</div>

2nd Column fill remaining screen height not working

I have a navbar with a fixed height, underneath a control div with also a fixed height and below that I have another div calendar. calendar is scrollable. I want the calendar height to have the remaining screen height below control and the bottom of the screen. This way the window is not scrollable, only the calendar is scrollable. However setting height: 100% does not work and flex: 1 neither.
This is what I have when I set the height of calendar to a fixed height but as I explained I want the height to be the rest of the screen size.
Any Idea?
.navbar {
height: 50px;
background-color: indianred;
}
.window {
display: flex;
flex-direction: column;
flex: 1;
}
.control {
height: 100px;
background: khaki;
}
.calendar {
height: 200px;
width: 100%;
bottom: 0;
left: 0;
}
.wrapper {
position: relative;
background-color: lightgray;
width: 100%;
height: 100%;
overflow: scroll;
}
.main {
width: 1500px;
height: 1500px;
background-color: rosybrown;
display: flex;
flex-direction: column;
}
<nav class="navbar"></nav>
<div class="window">
<div class="control">
</div>
<div class="calendar">
<div class="wrapper">
<div class="main">
</div>
</div>
</div>
</div>
Run this Code below:
I used height: calc() method full height of the screen minus 150px for nav and controls.
.navbar {
height: 50px;
background-color: indianred;
}
.window {
display: flex;
flex-direction: column;
flex: 1;
}
.control {
height: 100px;
background: khaki;
}
.calendar {
height: calc(100vh - 150px);
width: 100%;
bottom: 0;
left: 0;
}
.wrapper {
position: relative;
background-color: lightgray;
width: 100%;
height: 100%;
overflow: scroll;
}
.main {
width: 1500px;
height: 1500px;
background-color: rosybrown;
display: flex;
flex-direction: column;
}
<nav class="navbar"></nav>
<div class="window">
<div class="control">
</div>
<div class="calendar">
<div class="wrapper">
<div class="main">
</div>
</div>
</div>
</div>

canvas having odd behaviour with width and height

So I'm having some issues using <canvas>. It's taking up too much room when at 100% height and width and when it's set at only 100% height, it still causes and overflow for some reason.
Examples
With width and height at 100%, canvas takes up way too much room
.flex {
display: flex;
flex-direction: column;
height: 100vh;
}
.upper {
background-color: blue;
height: 10%;
}
.lower {
flex: 1;
background-color: orange;
}
html, body {
padding: 0;
margin: 0;
}
canvas {
height: 100%;
width: 100%;
background-color: red;
padding: 0;
margin: 0;
}
.inner {
width: 100%;
height: 100%;
background-color: yellow;
position: relative;
}
<div class="flex">
<div class="upper">
</div>
<div class="lower">
<div class='inner'>
<canvas></canvas>
</div>
</div>
</div>
Here, canvas is set at 100% height, yet it causes an overflow for some reason.
.flex {
display: flex;
flex-direction: column;
height: 100vh;
}
.upper {
background-color: blue;
height: 10%;
}
.lower {
flex: 1;
background-color: orange;
}
html, body {
padding: 0;
margin: 0;
}
canvas {
height: 100%;
background-color: red;
padding: 0;
margin: 0;
}
.inner {
width: 100%;
height: 100%;
background-color: yellow;
}
<div class="flex">
<div class="upper">
</div>
<div class="lower">
<div class='inner'>
<canvas></canvas>
</div>
</div>
</div>
