How to make a div 100% height of the browser window

Percentage Height HTML 5/CSS
(7 answers)
Closed 4 years ago.
So I am just starting to learn some basic CSS and now I have come across some behavior I don't understand. I have a <div> inside an <article> and the <div>s height is set to 100%. Now if all the parents parents of the <div> have their height specified then the height is equal to the parents height, however when it is not the case then <div>s height is smaller.
Here is a simple example when not all heights are specified:
html {
height: 100%;
}
article {
background-color: red;
height: 100%;
}
#side-nav {
background-color: blue;
float: left;
min-width: 10%;
height: 100%;
padding: auto;
margin: 0;
}
#main-content {
margin-left: 10%;
width: 90%;
}

</ul>
</div>
</article>
</body>
</html>
note that the <div>(colored in blue) is smaller than the direct parent <article>(colored in red).
So now my question is if there is a reason for this behavior and if there is some workaround to avoid specifying all heights?

You don't specify a height for your <body>, as such the rest of the height is stuck trying to figure out what it's 100% of.

Please set body{height: 100%}, will set the height of both blue and red to 100%, as shown in the below working snippet, hope it helps :)
html, body {
height: 100%;
}
article {
background-color: red;
height: 100%;
}
#side-nav {
background-color: blue;
float: left;
min-width: 10%;
height: 100%;
padding: auto;
margin: 0;
}
#main-content {
margin-left: 10%;
width: 90%;

Instead of floating the side-nav element to the left, you need to use flex.
Then you don't need to specify height on every element, as requested.
html {
height: 100%;
}
body {
height: 100%;
margin: 0;
}
main {
height: 98%;
display: flex;
flex-direction: row;
flex: 1 1 auto; /* grow shrink amount */
}
article {
background-color: #ffeeee;
flex-direction: column;
flex: 1 1 auto;
padding: 0.5em;
}
#side-nav {
background-color: #eeeeff;
flex-direction: column;
flex: 1 1 auto;
min-width: 11%;
padding: auto;
margin: 0;
}
#side-nav ul {
list-style-type: none;
margin-left: -2.5em;
}
#side-nav li a {
display: block;
white-space: nowrap;
padding: 0.25em;
}
#side-nav li a:hover {
display: block;
background-color: #0000ff;

Problem with figure caption in responsive image gallery using HTML+CSS

I'm currently making a (static) website from scratch (so code the HTML and CSS stuff myself), and I want to have a responsive "image gallery" that changes the width of the pictures according to your screen width, so I followed this tutorial: CSS Image Gallery - responsive
However, changing it to my own likings I encountered an issue I could not fix with my current HTML/CSS skillset (it is not that much, I'm quite new in this). My problem is when I have (in my example three) images of the same size in my gallery, but the captions of the image have different length, this negatively affects the text that is followed by the gallery (see example and image below). I tried to fix this with the tutorials available at W3 and stuff, but nothing worked yet.
Does any of you how to (easily) fix this? And if so, please explain what you changed, because I want to truly understand what is going on at my website (that is why I didn't want to use these static site generators).
Note: I have made 3 types of galleries, one for two, three and four images, which explains the ".responsivethree" etc classes

The float:left property you gave to the responsivethree class aligns the images to the left. Since you did not reset the left justification feature afterward, you are having a problem with the text scrolling. The clear:both command is used to reset the float:left property.

Can I change how Flexbox shrinks?

I'm trying to replicate the sections on the following page
I'm using flexbox in my version, however my version using flexbox seems to adjust to smaller screen sizes differently. For example the original that I'm trying to copy eats into the margin first as the screen gets smaller before adjusting the size of the text and images. When it does adjust the size of the the text and image it seems to do it a way that's a lot more asthetically pleasing. Once the screen size hits 960px wide I'm going to use media queries to set flexbox to block. However I'd like the text and images to adjust the same was the originally between 1440px and 960px. I've recorded a video to show what I mean - https://youtu.be/1pKq_UW-3Hk
And here's my code...
.section3-h1 {

I've observed that you have written so much redundant code in here. I have reframed you code.
please refer the code below. I have changed all classes and structure to reduce stylesheet overhead.

Also note that you should not use more than one h1 on one single page. This affects the SEO of your website. Instead use p or similar element with font-size to achieve large fonts.

Assign divs be exactly 100% height

My problem is the following: I have a website with a header, left navigation and a footer (not in the code right now). The header and the left navigation have to be static and only the rest of the page should move, that's why I started with making my left navigation menu 100% width. But height: 100%, doesn't seem to be working.
Could someone give me a tip or maybe anybody knows why I have this problem?
edit: that space under the footer and the left navigation shouldn't be there. That was a fail from when I took the screenshot.

You need to set height in "vh" instead of "%".
But you also need to calculate the height.. see example below
height: calc(100vh - height of header); If header height = 100px;
.leftnav {
height: calc(100vh - 100px);
}
Assuming height of navbar 70px and footer 100px and assuming width of sidebar 250px
.fullheight {
height: calc(100vh -170px);
width: calc(100vh - 250px);
overflow:auto
}
Also good to know, building layouts with flexbox CSS gives you some more freedom to play with elements shrinking and growing automatically instead of defining the height and width of the elements.
This can help you in the future to make better decision on to how to structure your HTML templates.
I coded you a quick example provided with your screenshot.

Div refuses to center

The problem should be able to be seen live at this link (on every page, as the main content of the page is contained by my "content" div): http://tucsonbagley.com/index.html
The "content" class (a container div) has a much larger margin on the left than on the right and, after going over my CSS ad nauseum, I just cannot figure out why. I've broken something for sure (it was working not long ago!), but I just can't figure out what.
If I remove my id Navbar or id Header divs, the Content div will default back to the left... yeah, at this point I'm lost.
The CSS in question:
.content{
display:inline-block;
margin:0 auto;
width: 68%;
overflow:hidden;
text-align: center;
padding: 10px;
background-color: #FFFFFF;
font-size: 12px;
border-radius: 10px 10px 10px 10px;
}
Example HTML:
<body>
<div class="header">
<p>Tucson Bagley</p>
</div>
<div id="socialmedia">
<img src="images/Twitter_logo_blue.png"/>
<img src="images/linkedin.png"/>

<div id="header">

<div id="navbar">

<li><span>Contact me</span></li>
</ul>
</div>
<div class="content">
<div class="thumbleft"><h2>This is some content.</h2>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Proin non varius metus. Pellentesque eu nunc tortor. Aliquam id lectus orci. Sed id consectetur eros. Curabitur semper nisl nibh, rhoncus lacinia nibh volutpat at. Pellentesque sollicitudin vitae ipsum ut dictum. Proin ac risus ac nisi interdum hendrerit. Pellentesque sodales mauris ac eleifend vehicula. Nulla convallis aliquet urna varius auctor. Donec eget ipsum ut mauris consequat auctor eget sit amet odio. Nullam sed lorem erat. Praesent consequat porttitor magna, sit amet feugiat odio tincidunt ut. Fusce congue eros vel quam condimentum, vel consectetur quam imperdiet. </p>
</div>
</br>
<div id="copyright">

</div>
</body>
Some help would be appreciated. Thanks in advance!
Add a <div style="clear:both"></div> before .content div and apply display:block to .content instead of display:inline-block and that's it
change the css of your .content to look like this
.content{
position: absolute;
left:0px;
right:0px;
display:inline-block;
margin:10px auto;
width: 68%;
overflow:hidden;
text-align: center;
padding: 10px;
background-color: #FFFFFF;
font-size: 12px;
border-radius: 10px 10px 10px 10px;
}
the magic is the left:0px combined with right:0px and margin:10px auto which will only work in absolute mode.
Edit - updated css as per comments.

Why is my aside at the bottom of this page?

I'm wondering why my aside is at the bottom of the page instead of next to the main content when I apply (float:right;) in the css. I've tried to float it on the left and the main content on the right but had the same problem.

You haven't accounted for the padding in your widths. If you reduce your widths to those below, the aside will move back to the side.
article {
background-color: #CBE86B;
float: left;
padding: 0 20px 40px;
width: 560px; /* 560px + 20px + 20px = 600px */
}
