Make flex element ignore child element
CssHtmlFlexboxCss Problem Overview
Is it possible to make a flex element ignore a child element so it's size does not affect the other elements?
For example, I have a wrapper with display: flex
. It has a header, content, and footer.
<div class="wrapper">
<header></header>
<article></article>
<footer></footer>
</div>
I want the wrapper to ignore the header tag (the header will be fixed to the top of the window). The article will be set to flex: 1
so it takes up the rest of the space, forcing the footer to the bottom of the page. Here is some sample CSS:
.wrapper {
display: flex;
flex-direction: column;
height: 100%;
padding-top: 50px; /* Accounts for header */
}
header {
height: 50px;
position: fixed;
top: 0;
width: 100%;
}
article {
flex: 1;
}
footer {
height: 50px;
}
I know I could just move the header outside of the wrapper but I have a lot of existing code that will make that a bit more difficult. Is what I am asking even possible?
Css Solutions
Solution 1 - Css
In your .wrapper declare flex-wrap: wrap
. Then for your header, you can add the style flex-basis: 100%
which will force everything else down below the header.
Solution 2 - Css
Use position: absolute
for the child element to exclude it from the flex calculations
Solution 3 - Css
You can use flex-shrink: 0
on the child elements to keep them from shrinking to fill the container. And use flex-wrap: wrap
on the container/wrapper so your children will wrap down.
Solution 4 - Css
Use flex: 0 0 100%;
to the child you want to be in a new line and add flex-wrap: wrap
on the wrapper.
Solution 5 - Css
If trying to use flex-direction:column
, the only thing that I found helpful for that is absolute positioning / with the corresponding padding.
Solution 6 - Css
Add flex-wrap: wrap
on the wrapper where you're having display: flex
on.
That did the trick for me.
