Flexbox footer not stacking under other divs - html

I created a layout using css and Flexbox, the issue is the footer div displays at the bottom of the page on load, but content shoots past it, so when you scroll the footer is just floating in the middle of the page. I'm not sure what to change.
I have changed the footer to be sticky, and bottom to be 0px. It kinda worked with adjusting the margin of the other divs, but its not very clean. I was hoping to keep using the flexbox attributes and just have them stack, but that doesn't seem to work? I've also adjusted the min-max heights of the other divs, but as soon as the window shrinks past the min height the footer just floats over the rest of the content.

.footer{
height:40px;
display:flex;
align-items:center;
justify-content:center;
width:100%;
background-color:purple;
}
I would suspect that the footer would obey the stacking order and just display under the rest of the content, like the main body does under the header.

It's the height set on your '.content' class. Change height: calc(100vh - 100px) to min-height: calc(100vh - 100px)
Unless you want the footer and header always visible, then you can just add overflow: auto to make the content scroll

Remove height: calc(100vh - 100px); from .content class
body,
html {
height: 100%;
width: 100%;
padding: 0;
margin: 0;
}

flex-wrap: wrap;

There are a few things did to do to make this work:
Originally the scrolling was happening on the body. I added overflow: hidden on the body and overflow-y: auto to the div with the "bodywrap" class.
I added the position sticky and bottom 0, but with vendor prefixes:
bottom: 0;
position: -webkit-sticky;
position: -moz-sticky;
position: -ms-sticky;
position: -o-sticky;
I also made the div with class "bodywrap" have a height equal to 100vh minus the height of the footer (so that the scrolling content doesn't get cutoff at the bottom). You may want to set a sass variable or something for this 40px height.
height: calc(100vh - 40px);
Here's a demo of the new version:

Why do my image gets cropped when resized in browser?

When height is reduced below certain limit the image placed at top of div is not visible and cannot be scrolled up as shown in the pictures. Can anyone tell on how to solve this.
Webpage when resized:
Full webpage:
body {
display: flex;
justify-content: center;
height: 100vh;
align-items: center;
}
.box {
background: lightblue;
width: 300px;
height: 500px;
min-height: 300px;
}
img {
position: relative;
top: -20px;
left: 120px;
}
<div class="box">
<img id="xy"src="https://placeimg.com/50/50/animals">
</div>
At "body" part of css, try "min-height" instead of "height".
/*your code*/
body{
display: flex;
justify-content: center;
height: 100vh;
align-items: center;
}
.box{
background: lightblue;
width: 300px;
height: 500px;
min-height: 300px;
}
/*try this one instead ("min-height" instead of "height") and (added "margin-top: 5vh" to ".box")*/
body{
display: flex;
justify-content: center;
min-height: 100vh;
align-items: center;
}
.box{
margin-top: 5vh;
background: lightblue;
width: 300px;
height: 500px;
min-height: 300px;
}
Your img is positioned relative to the nearest positioned ancestor. That means it is being placed -10px beneath the body, because .box does not have any position set.

flexbox justify-content causes overflow: auto not work correctly

I have a container div that its content can grow vertically. I used overflow-y: auto for the container to make my page look good. But I need to place everything in the center when the content's height is smaller than the container's. So I used flexbox to do that. But the problem is that I can't scroll completely to see the top part of the contents.
Here is a simple example of the problematic code:
<html lang="en">
<head>
<style>
.container {
width: 20rem;
height: 20rem;
background-color: red;
display: flex;
justify-content: center;
flex-direction: column;
align-items: center;
overflow-y: auto;
}
.child {
width: 10rem;
height: 40rem;
background-color: blue;
flex-shrink: 0;
}
.top {
width: 1rem;
height: 1rem;
background-color: green;
}
</style>
</head>
<body>
<div class="container">
<div class="child">
<div class="top"></div>
</div>
</div>
</body>
</html>
One of the solutions to this problem is to use the reverse order of the elements in the flex-container, i.e. in your case, using flex-direction: column-reverse instead of flex-direction: column.
Example #1 below:
.container {
width: 20rem;
height: 20rem;
background-color: red;
display: flex;
justify-content: center;
flex-direction: column-reverse;
align-items: center;
overflow-y: auto;
}
.child {
width: 10rem;
min-height: 0;
height: 40rem;
background-color: blue;
flex-shrink: 0;
max-height: 150%;
}
.top {
width: 1rem;
height: 1rem;
background-color: green;
}
<div class="container">
<div class="child">
<div class="top">test</div>
</div>
</div>
The second solution is to consider using for center alignment, you can also use justify-content: space-between and pseudo-elements ::after and ::before.
Example #2 below:
.container {
width: 20rem;
height: 20rem;
background-color: red;
display: flex;
justify-content: space-between;
flex-direction: column;
align-items: center;
overflow-y: auto;
}
.container::before,
.container::after {
content: '';
}
.child {
width: 10rem;
min-height: 0;
height: 40rem;
background-color: blue;
flex-shrink: 0;
max-height: 150%;
}
.top {
width: 1rem;
height: 1rem;
background-color: green;
}
<div class="container">
<div class="child">
<div class="top">test222</div>
</div>
</div>

How to enable scrollbar with non-fixed height in a window-centered div?

I am creating a div which is centered to the window. It's content can grow, and if it grows passed the size of the window, the content div should have it's scrollbar account for the overflow. But instead, the div just grows off the screen and gets clipped. If I set an explicit height on the content, everything works, but since I don't know the explicit height of the environment I cannot do that. What is the correct way to do this?
JSFiddle: https://jsfiddle.net/CodeVirtue/cjhz31xq
Here is the template:
<div class="fullscreen-overlay">
<div class="fullscreen-container">
<div class="window-with-titlebar">
<div class="titlebar">
<div class="titlebar-left">
Left
</div>
<div class="titlebar-right">
Right
</div>
</div>
<div class="content">
1<br>2<br>3<br>4<br>5<br>6<br>7<br>8<br>9<br>10<br>11<br>12<br>13<br>14<br>15<br>16<br>17<br>18<br>19<br>20<br>21<br>22<br>23<br>24<br>25<br>26<br>27<br>28<br>29<br>30<br>31<br>32<br>33<br>34<br>35<br>36<br>37<br>38<br>39<br>40
</div>
</div>
</div>
</div>
And all the CSS:
* {
box-sizing: border-box;
}
body {
margin: 0;
padding: 0;
overflow: hidden;
}
.fullscreen-overlay {
background-color: red;
display: flex;
justify-content: center;
align-items: center;
width: 100vw;
height: 100vh;
padding: 12px 12px;
}
.fullscreen-container {
background-color: orange;
display: flex;
justify-content: center;
align-items: center;
width: 100%;
height: 100%;
max-width: 100%;
max-height: 100%;
overflow: hidden;
}
.window-with-titlebar {
background-color: yellow;
max-width: 100%;
max-height: 100%;
}
.titlebar {
background-color: green;
display: flex;
align-items: center;
justify-content: space-between;
height: 30px;
}
.titlebar-left {
background-color: darkgreen;
}
.titlebar-right {
background-color: lightgreen;
}
.content {
background-color: blue;
overflow-y: scroll;
max-width: 100%;
max-height: 100%;
}
I believe I was able to achieve what you are looking for by making the parent container use flexbox:
.window-with-titlebar {
background-color: yellow;
max-width: 100%;
max-height: 100%;
display: flex;
flex-direction: column;
}

Exclude height of existing div when setting viewport height for another div

I'm working on a page that has a header nav, then two rows of banner images, then a couple more divs below the banners.
What I'd like to achieve is to have the nav div be a set height (90px) and then have the two rows of banners evenly split the remaining viewport height of the user's browser. Then, have the two divs below the banners also be fixed pixel heights.
Here's a snippet of my stripped down code:
html, body {
margin: 0;
padding: 0;
}
.nav {
background: red;
height: 90px;
display: flex;
justify-content: center;
align-items: center;
}
.banners-row-1 {
background: green;
display: flex;
justify-content: center;
align-items: center;
height: 50vh;
}
.banners-row-2 {
background: orange;
display: flex;
justify-content: center;
align-items: center;
height: 50vh;
}
.mailing-list {
height: 115px;
background: pink;
display: flex;
justify-content: center;
align-items: center;
}
.footer {
height: 117px;
background: lightblue;
display: flex;
justify-content: center;
align-items: center;
}
<div class="nav">
This is the nav
</div>
<div class="banners-row-1">
Banners Row 1
</div>
<div class="banners-row-2">
Banners Row 2
</div>
<div class="mailing-list">
Mailing List
</div>
<div class="footer">
Footer
</div>
As you can see, the two banner rows are set to 50vh, which is close to what I want - but, is there a way to somehow incorporate the 90px nav div when the banner divs calculate the viewport height?
Essentially, what I'm after is something along the lines of 50% of 'viewport height minus 90px'...?
Thanks
Wrap your nav and banners to wrapper and use following flex properties:
html, body {
margin: 0;
padding: 0;
}
.nav {
background: red;
height: 90px;
display: flex;
justify-content: center;
align-items: center;
}
.wrap {
display: flex;
flex-direction: column;
height: 100vh;
}
.ban {
flex: 1;
}
.banners-row-1 {
background: green;
display: flex;
justify-content: center;
align-items: center;
}
.banners-row-2 {
background: orange;
display: flex;
justify-content: center;
align-items: center;
}
.mailing-list {
height: 115px;
background: pink;
display: flex;
justify-content: center;
align-items: center;
}
.footer {
height: 117px;
background: lightblue;
display: flex;
justify-content: center;
align-items: center;
}
<div class="wrap">
<div class="nav">
This is the nav
</div>
<div class=" ban banners-row-1">
Banners Row 1
</div>
<div class="ban banners-row-2">
Banners Row 2
</div>
</div>
<div class="mailing-list">
Mailing List
</div>
<div class="footer">
Footer
</div>
It works, because space in .wrap is splitted like:
.nav has fixed 90px
.bans have equal left space (100vh - 90px) / 2

Flexbox "align-items : center" shrinks a child's max-width

I have a flexbox div container with align-items: center, with three childs. One of them has max-width: 200px (in the code, second-ch), and it's also a flex with two childs distributed with justify-content: space-between, but second-ch is not following its max-width. If I remove align-items: center from container, second-ch takes again the width desired but the remaining elements are not in the center anymore. How can I solve that?
.container {
display: flex;
flex-direction: column;
justify-content: space-between;
align-items: center;
}
.first-ch {
width: 70px;
height: 70px;
background-color: grey;
}
.second-ch {
max-width: 200px;
height: 80px;
background-color: red;
display: flex;
justify-content: space-between;
}
.square {
width: 50px;
height: 50px;
background-color: yellow;
margin: 5px;
}
.third-ch {
width: 50px;
height: 50px;
background-color: blue;
}
<div class="container">
<div class="first-ch"></div>
<div class="second-ch">
<div class="square"></div>
<div class="square"></div>
</div>
<div class="third-ch"></div>
</div>
Citing the comment of Jason Deppen:
I solved it by also setting width: 100% along with my max-width value.
max-width: <your max width>;
width: 100%;
Why is this happening ?
It's not really the effect of align-items: center. It's the omision of the default value, align-items: stretch , that makes the child grow.
.container {
display: flex;
flex-direction: column;
justify-content: space-between;
align-items: stretch; /* default */
}
.first-ch {
width: 70px;
height: 70px;
background-color: grey;
}
.second-ch {
max-width: 200px;
height: 80px;
background-color: red;
display: flex;
justify-content: space-between;
}
.square {
width: 50px;
height: 50px;
background-color: yellow;
margin: 5px;
}
.third-ch {
width: 50px;
height: 50px;
background-color: blue;
}
<div class="container">
<div class="first-ch"></div>
<div class="second-ch">
<div class="square"></div>
<div class="square"></div>
</div>
<div class="third-ch"></div>
</div>
If you want the child to grow until it reaches the width-max, do as bolverin says and set the width explicitly
I know this is old but for anyone reading this:
Using align-self: stretch; on the child element will also work :)
So in this case:
.container {
display: flex;
flex-direction: column;
justify-content: space-between;
align-items: center;
}
...
.second-ch {
max-width: 200px;
align-self: stretch;
...
}
...
why do you use max-width: 200px;? try width: 200px;
when you use align-items : center the .second-ch has minimal needed width.
max-width limits max width of the block but doesn't set minimal width
