<div style="height: 100%; background: red">
<div style="height: 100px; background: green">
</div>
<div style="background: blue;">
<h1>Content</h1>
</div>
</div>
Is there a way to center the content of the blue box in the free space of the red block, with the parent block maintaining a height of 100%?
Similar to this:
One solution for this problem is to utilize flexbox.
* {
margin: 0px;
padding: 0px;
}
.h {
height: 100px;
background: green;
}
.m {
background: blue;
color: white;
display:flex;
flex-direction: column;
align-items: center;
justify-content: center;
height: calc(100vh - 100px);
}<div class="w">
<div class="h">header</div>
<div class="m" >
<h1>Content</h1>
</div>
</div>Learning about the flex-box layout can greatly simplify your alignment tasks and will not disappoint you. Make sure to check out these resources: (https://www.w3schools.com/css/css3_flexbox.asp) (Another helpful resource on flex-box, which is a personal favorite of mine: https://css-tricks.com/snippets/css/a-guide-to-flexbox/)
If this doesn't meet your needs, please let me know so I can adjust accordingly.
