I have a header and a content div inside a container div. I want the header's height to be fixed and the content div to occupy the rest of the container div. The easy solution is to set the height of the content div as (container-header) pixels. Is there an alternate way of doing it ?
div.container { height: 300px; width: 100%;}
div.container h2 { height: 15px }
div.container div.content { height: ?? }
I do not believe you can do this with simple CSS. However, it is trivial to implement when using a CSS preprocessor like LESS or Sass. Both less and sass have support for variables, so you can do something like this:
#total-height: 300px;
#h2-height: 15px;
div.container { height: #total-height; width: 100%;}
div.container h2 { height: #h2-height}
div.container div.content { height: #total-height - #h2 }
Note: I have not compiled / tested this code. But you get the idea.
In the first place, you don't need to set the div.container's width to 100%. You get that for free.
Second, if you have a fixed height for the container, it's simple arithmetic to subtract the header (15px) from the container (300px). Simple is good.
If your container's height is not fixed, you can try absolute or relative positioning to nail the bottom of the content div to the bottom of the parent (e.g., bottom: 0px). But you apparently have no need of that here.

I am trying to put a div on the left side of my webpage that has not to be fixed and has to be 100% of the height and 30% width. I mean, that if you scroll, it will be scrolled also and it will not be fixed in the same position all the time.
The problem that I am having it is that when I put height: 100%; it does not cover the height that I am indicating to him. It only covers the full height when I set position:fixed but never when I set it to static, absolute or relative.
What I though it is that it could be that I had to set width: 100%; and height: 100%; to the <html> tag but it does not seem to have any difference if I compare it with <body> tag (I know there are differences between both tags but I do not know if in this case they will be aplied, I think no).
Here is my html code:
<html>
<head>
</head>
<body>
<h1>This is a prove</h1>
<div id="proveDiv">
<h1>Hello</h1>
</div>
</body>
</html>
Here is my CSS code:
html{
/* position: relative; I comment these lines because I saw that there are not any effect
width: 100%;
height: 100%; */
}
body{
position: relative;
width: 100%;
height: 100%;
}
#proveDiv{
position: fixed;
width: 30%;
height: 100%;
background-color: red;
}
Here is the fiddle in which you can see the effect. Just try to change the position attribute on proveDiv id css and you will se what I refer to.
I am stuck here and I cannot find any solution by myself or in SO. Am I missing something?
Thanks in advance!
Set the min-height of the div to view-port height like min-height: 100vh;. Updated fiddle
#proveDiv {
width: 30%;
min-height: 100vh;
background-color: red;
}
Based on your description, this is the working demo that I came up with.
http://codepen.io/BenCodeZen/pen/JXLbjN
The solution is based on a display: flex; on a parent container and defining the height of the element using height: 100vh; instead of 100%. By using flexbox, it will allow you more control over the layout for responsive design.
Let me know if you have any questions.
The reason why this happens is because, when you use the attribute fixed, for some reason, the div's height will increase because it's inherited by default from its container. In this case, when your div is fixed and its height is set to 100%, the div takes the full height of its container which is the body.
PS: In case you want the div to have its initial height, you can use position:initial.
On the other side, using position:relative is your best option.
By default, the div will have its own initial height which depends on its content. When you have more text inside your div, it will automatically increase its height.
To solve your problem, use a relative position and set the height as you want. (100% will make the div take the height of the body)
Note that it is important that you set both the body & html tag's height otherwise it won't work. (If you need further explaination, just comment below)
This is how your CSS should be:
html,body{
width: 100%;
height: 100%;
}
#proveDiv{
position: relative;
width: 30%;
height: 100%;
background-color: red;
}

I've created the following demo to show my issue:
http://francisbaptiste.com/nov17/
Each div is 33.33% wide. Within the div is an image with 100% width. I want it to be a perfect grid of images, but the height of the div is always a little more than the height of the image.
Shouldn't the height of the div be set by the height of the image within it? So why is there that little bit of space at the bottom?
The gap is coming from the actual whitespace after the image tag. You can use this to fix it:
.card img {
display: block;
}
Fiddle
Or a more hacky solution:
.card {
font-size: 0;
}
Fiddle
I thinks the problem is the height of outer div, you cannot use auto since the browser may have some default action for the div and its inside content. Instead, I specify the percentage of height and solved the problem
.card {
width: 33.333%;
height: 50%;
overflow: hidden;
float: left;
background: black;
color: white;
}
Does that make sense to you?
Is there a way that I could set a DIV element to take up all the height on the page. Something like:
div.left {
height: 100%;
width: 50%;
background-color: blue;
position: absolute;
top: 0;
left: 0;
}
I've Google'd it a few times but they all seem like really really complicated work arounds for what is probably a really really simple problem with a simple solution.
If the div is a direct child of body, this works:
body, html {height: 100%; }
div { height: 100%; }
Otherwise, you have to keep adding height: 100% to each of it's parents, grandparents,... untill you've reached a direct child of body.
It's simple. For a percentage height to work, the parent must have a specified height(px, %... whichever). If it does not, then it's as if you've set height: auto;
Another way to do it is as you have in your answer: it's to give it an absolute position value, relative to the element that defines the page's height.
This is the simplest way to make a div take up the full height of a page.
height: 100vh;
vh is Viewport Height, and 1vh is equal to 1% of the height of the viewport. See here for more details on this and other units of measurement in CSS.
Make sure you set height: 100% to html and body so that the div has a context for height! Hope that helps.
Pretty sure you need to set the html and body to 100%:
html {
height: 100%;
}
body {
height: 100%;
}
div.left {
height: 100%;
}
Fiddle here.
This problem can be solved using CSS flexbox.
Go through the w3schools documentation of flexbox here and another helpful link css-tricks here
In this scenario.
put display: flex; in the parent div container
div.container{
height: 100%;
display: flex;
}
then in the child div put display: 1;
div.left{
height: 100%;
display: 1;
}
note that if the height of the parent div container is set dynamically, the child div will always have the same height as the parent.
I'm trying to get a simple solution for this layout.
This is the simplified html.
<div class='wrapper'>
<div class='header'></div>
<div class='middle'> TEXT </div>
<div class='footer'></div>
</div>
Header and footer have a fixed height in pixels.
middle can have a variable height, depending on the content.
I want wrapper to have a minimum height of 100%. So if the text inside middle is small, the middle div should expand to fill the browser page. And if it's too long, the whole page should be scrollable.
Is this possible easily? Maybe changing something in the layout?
here's your solution: http://jsfiddle.net/S4akv/1/
You do NOT want to set a hard height for the .middle. If your content is only a few lines then you will end up with scrollbars where none are needed.
With a header and footer, you also don't want height: 100% on your .middle class because it will push your footer down, forcing a scrollbar no matter what. You also don't want a clear-cut height:100% because most browsers will interpret this as 100% of the browser height, so when you resize your browser to be larger, either the height won't change or the footer won't move.
The best solution here is to have your wrapper and any associating backgrounds attached to that. Depending on the content within your .middle div this answer could change, but given the simple parameters this is the most elegant way to do it.
the secret is to make sure that all containing elements have a height set. reason being, any block element with height: 100% will only be 100% of the area containing it. in this case you need to set height for middle, wrapper and body, html
body,html { height: 100%; margin:0; padding:0; }
.wrapper { min-height: 100%; width: 100%; background-color: red; position:relative; padding-bottom: 200px; }
.header { height: 200px; width: 100%; background-color: blue; }
.middle { }
.footer { height: 200px; width: 100%; background-color: green; position:absolute; bottom: 0; }
If you have nested content within .middle that also needs to be 100% height there is a better way, using a combination of height, absolute positioning and negative margins. There are a million ways to skin a cat. Well, a handful at least :)
edited to add padding to .wrapper to make room for footer. The bottom padding of wrapper must be the same height as the footer
I have a website with two columns, within a wrapper div.
The wrapper has the same height as the tallest div by giving floating everything and giving the wrapper height:100%.
Here's my problem: one of the columns is a div with overflow:scroll and several images in it. I tried to set its height to 100%, thinking that it would take up the full height of the wrapper. Instead, it became the height of all the images on top of each other.
If I set the height of the column with images (#rightbox) to a specific height in pixels, this happens.
I want it to have the same height as the other div with text, so I set its height to 100%. Then this happens.
How can I make the two columns have the same height?
EDIT: I forgot to mention that the amount of text varies, so I can't define a specific height for the wrapper.
You cannot define height as 100% unless your parents provides an actual heights.
#wrapper {
height: 800px;
}
/* Now you can make the columns inside take the full height of its parent *?
#wrapper .columns {
height: 100%;
overflow: auto;
}
Note: if the wrapper sits inside the body element then you will need to set html,body { height: 100%; } before the wrapper can be set to 100%
Given the limited amount of code provided... here is a pure css solution.
http://jsfiddle.net/rlemon/Q7MvS/
.wrapper {
height: 600px;
width: 800px;
}
.panel {
float: left;
width: 400px;
height: 100%;
}
.panel.right {
overflow: scroll;
}
