100% height for a div in jQuery

Question

I would like to put a <div id="design"> (in red on the picture) with a height of 100%. But I didn't manage to. This is possible in CSS or it's better in jQuery ?

Can you help me please ?

#design {
    width: 100%;
    height: 100%; /* Don't work */
    margin-top: 40px;
    background: red;
    border: 2px solid black;
}

Answer 1

height: 100%; works when an a height is set on the parent element. Since you have not shared your markup I cannot point out exactly what element might be the parent of #design . Either set a height on the parent element of #design , using whatever units you'd like, or use a unit other than a percentage value on #design .

Working Example:

.outer {
    height: 250px;
}
.inner {
    height: 50%;
}

<div class="outer">
    <div class="inner">I will be 125px tall.</div>
</div>

NON Working Example:

.outer {
    height: 250px;
}
.inner {
    height: 50%;
}

<div class="outer">
    <div class="middle">
        <div class="inner">I will only be as tall as the space this text takes up.</div>
    </div>
</div>

You need to add overflow : auto; in #design and overflow : hidden; in 'aside' class.

aside, main {
    padding: 40px 0;
    background-color: #7d7d7d;
    border: 2px solid black;
    overflow : hidden;
}

#design {
    width: 100%;
    height: 100%;
    margin-top: 40px;
    background: red;
    border: 2px solid black;
    overflow : auto;
}

Actually, setting an element in a column to have same height as some other column using CSS is pretty painful. You can use tables for that, but that's pretty 90's-ish.

If you can rely on that your users will use modern browsers ( IE10+ ), I recommend you use CSS3 Flexbox - you'll achieve what you need quite easily. See https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for tutorial and explanation of possible options.

See this altered fiddle (use Firefox or Chrome, I didn't use all necessary vendor prefixes): https://jsfiddle.net/1htd7pbt/1/

Basically, I just added this:

#content .row {
    display: flex;
    align-items: stretch;
}

#content aside {
    width: auto;
    display: flex;
    flex-direction: column;
    padding-bottom: 0;
}

#design {
    flex-grow: 1;
}

A little bit of tweaking here. I removed the row class from your header and put the padding in your form and design separately. But it works. Here is the fiddle result (just removed the embedded/result to see the fiddle)

 html, body { height: 100%; } .mw1140p { max-width: 1140px; margin: 0 auto; } .row { clear: both; } .row { display: table; table-layout: fixed; width: 100%; height: 100%; } .row > *, .col { display: table-cell; vertical-align: top; } aside .w25 { width: 25%; height: 100%; } .w75 { width: 75%; height: 98%; overflow-y: hidden; } header { height: 70px; background-color: #7d7d7d; border: 2px solid black; } #logo { height: 40px; } main { padding: 40px 0; background-color: #7d7d7d; border: 2px solid black; } label { color: white; } input { width: 98%; margin: 10px 0; } aside form { width: 100%; height: 18%; background-color: #7d7d7d; border: 2px solid black; padding: 40px 0; overflow: hidden; } #design { width: 100%; height: 82%; padding-top: 20px; background: red; border: 2px solid black; overflow: hidden; } h3, p { color: white; }

Answer 5

You should use CSS for these purposes. Jquery is hard. Just use only vh instead of %.

#design {
  width: 100%;
  height: 100vh;
  margin-top: 40px;
  background: red;
  border: 2px solid black;
}

You can find more explanation of vh in this link .
