I have a lot of space under the footer, and this is something that I would really like to get rid of. For some reason, this space only appears in Google Chrome and not in Firefox.
Heres an image showing it.
http://puu.sh/a6XQI/ec07f0ba31.jpg
What I would like to have happen is my content resize according to the screen size. I am not sure if I can do that because I dont have much content, just a few images.
Any suggestions would be appreciated.
Since you didn't provide any code, I would assume this has to do with the height of you page content being shorther than your window height. Many people who come from a print design background are often perplexed by the concept that a footer doesn't automatically appear at the bottom of a page. The position of dynamically sized elements depends on their content, which as you may come to find out, is very frustrating when a client wants a website built BEFORE providing any content. But I digress.
Assuming the root problem is caused by my former assumption, to achieve what is known as a sticky footer, implement the following to your existing page structions:
jsFiddle: http://jsfiddle.net/63mp6/
HTML
<div class="primary">
<div class="header">
Header Content
</div>
<div class="content">
Main body Content
</div>
<div class="footer">
Footer content
</div>
</div>
CSS
*{
box-sizing: border-box;
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
}
html, body {
position: relative;
width: 100%;
height: 100%;
background: #eee;
}
.primary {
position: relative;
width: 80%;
height: 100%;
margin: 0 auto;
}
.header{
min-height: 100px;
min-width: 100%;
background: #aaa;
}
.content {
min-width: 100%;
min-height: 200px;
background: #fff;
}
.footer {
position: absolute;
bottom: 0;
left: 0;
width: 100%;
min-height: 100px;
background: #666;
}
What's happening here is you're resetting default styling to the parent containers, forcing them to 100% height of the window and then telling the footer position about of the default page flow to the bottom of it's parent container. Notice the position: relative; attributes on the primary and html, body definitions. Those set the tone for their child elements to be relative to them instead of the window. Without the position declarations, the child elements would position themselves to the highest element with a relative position, which would be the window itself.

I have been tasked with styling a banner, however the banner itself is a third party tool with severely limited styling options. It's probably easier if I share an example of what I'm working with and then talk through the limitations and what I'm trying to achieve.
body {
margin: 0;
}
.main {
height: 200vh;
min-height: 250px;
width: 1200px;
background: #cdcdcd;
margin: 0 auto;
padding: 20px;
}
<div class="main">
Main website content
</div>
<div class="banner" style="position: fixed; width: 100%; max-width: 600px; height: 80px; background: gray; bottom: 20px; right: 20px; color: white; padding: 20px;">Banner content</div>
Here is a version in Codepen if that's easier.
As you can see, the main website content is centered and is responsive up to (in this case) 1200px, after which the width becomes fixed. The banner needs to always sit at the bottom right, but it should remain within the constraints of the main website content. When the viewport is less than 1200px this solution works fine, the issue I have is of course that on viewports wider than 1200px, the banner breaks out of the constraints of the site.
Generally this wouldn't be an issue, it's easily fixed with calc() and a media query to get the viewport width, but now come the limitations of the banner tool:
I can only add inline CSS via the tool to the element banner, there is no wrapper or inner element I can target
I cannot add CSS to the site that the banner will appear on
I cannot use JavaScript, either on the site or in the banner tool
I can't affect the HTML mark-up in any way (e.g. I can't put the banner inside main
Sorry for the long introduction but hopefully that explains my dilemma. My question is this: is it possible, using CSS calc(), to determine when my viewport is above 1200px and to add (half) that amount to my right offset without affecting the offset when the viewport is less than 1200px, or is there just no solution to this?
Here is one idea that rely on the use if min() in order to define the max-width. You make it either 600px (for bigger screen) or 50% (for small screen) and then adjust the position using translate after centring the element:
body {
margin: 0;
}
.main {
height: 200vh;
min-height: 250px;
width: 1200px;
background: #cdcdcd;
margin: 0 auto;
padding: 20px;
}
* {
box-sizing:border-box;
}
<div class="main">
Main website content
</div>
<div class="banner" style="position: fixed; width: 100%; max-width: min(50%,600px); height: 100px; background: gray; bottom: 20px; right: 0;left:0;margin:auto;transform:translate(50%);border:1px solid red; color: white; padding: 20px;">Banner content</div>
The support is still not good (https://caniuse.com/#feat=mdn-css_types_min) but shortly it will be available on Firefox and all the major browser will be covered.
is there any way to make single page website without position absolute? Because when I want to variable height of containers, absolute position is little bit awkward. I mean when I insert more content to one container, the other above it should move down. I've tried position static and relative, but it didn't work for me.
Now my css looks like:
<style>
#header {position: absolute; top: 0; left: 0; width: 100%; height: 20%;}
#main {position: absolute; top: 20%; left: 0; width: 100%; height: 80%;}
#about {position: absolute; top: 100%; left: 0; width: 100%; height: 100%;}
#contact {position: absolute; top: 200%; left: 0; width: 100%; height: 50%;}
</style>
<body>
<div id="header">
content....
</div>
<div id="main">
content...
</div>
<div id="about">
long content which is covered with next div, because its "top" atribute settings
</div>
<div id="contact">
div which covers previous one's end
</div>
But when some container needs to be longer, problem is here..
Thanks for any help!
That depends on the style of your website. Of course you can set up anchors and have a one-page scrolling website, but I don't think that answers your question.
My suggestion is to try using absolute positioned elements as containers, and have your actual template inside them.
It would help if you provided some actual code or a specific issue you're having, as it's currently too vague.
I'll provide an answer to what I think you might be asking, though it isn't clear. I hope this isn't too basic.
Ditch the position property altogether.
Just have a div (which is by default 100% width) as your header at the top of your html. The content should be in another div below that.
Divs by default have 100% width, and their height is dependent on the height of their content. They will grow to accommodate taller content. These behaviors are because they have the property display:block .
You've used % which, if I remember correctly, is relative to the parent element. vh (viewport height) is relative to the height of the screen (100vh is the full height of the screen).
I added the background-color just so it's easier to see.
<style>
#header {
background-color: #777;
height: 20vh;
}
#main {
background-color: #999;
height: 80vh;
}
#about {
background-color: #777;
height: 100vh;
}
#contact {
background-color: #999;
height: 50vh;
}
</style>
In the following fiddle:
http://jsfiddle.net/6qF7Q/1/
I have a yellow content area that has a min-height set to 100% - it's the background div to all pages and should take up at least 100% of the available height. If there's overflow, it expands vertically.
Then, within that yellow container, I have another child div (red) that I would like to take up as much vertical space as its parent. It seems I can't set height because the parent element only has min-height, and setting min-height on the red element doesn't work either.
So right now, the yellow is behaving as I'd like, but the red is not expanding. How can this be achieved with CSS only?
CSS:
.browser {
background-color: blue;
height: 600px;
width: 200px;
position: relative;
}
.innercontent {
min-height: 100%;
background-color: red;
width: 100%;
color: white;
padding: 2px;
}
.content {
background-color: yellow;
width: 100%;
min-height: calc(100% - 30px);
}
.footer {
position: absolute;
bottom: 0px;
left: 0px;
width: 100%;
background-color: orange;
height: 20px;
}
HTML:
<div class="browser">
<div class="content">
<div class="innercontent">
This is the problem - I need this to take up 100% of the remaining yellow space, without setting the parent element's 'height' - only min-height is specified in the parent because I need to make sure that it takes up 100% of the height at least, but allow it to extend vertically if there's any overflow.
</div>
should not see any yellow
</div>
<div class="footer"></div>
</div>
Take a look at this
I added this
*{
box-sizing: border-box;
}
html, body {
/* Make the body to be as tall as browser window */
height: 100%;
}
and changed some attributes u can see at fiddle
If thats what you want you should read this article
http://css-tricks.com/a-couple-of-use-cases-for-calc/
I made that based in this use-cases
I think this might solve your issue?
I have changed the innercontent to position: absolute
http://jsfiddle.net/6qF7Q/7/
If you have text in the yellow section it will always show.
Also, you're going to have to do a bit of fiddling to get your footer positioned correctly since you are going to have an overflowing absolute element. I think a full body position: relative wrapper will solve it.
P.S I don't see why you would need a .content AND a .innercontent if you don't want the .content to show?
This works much better and doesn't give you footer grief: http://jsfiddle.net/6qF7Q/9/
I want to have a site that is 100% of the height of the browser at all times, with the width scaling with an aspect ratio when the height is changed.
I can achieve this using the new vh unit: http://jsbin.com/AmAZaDA/3 (resize browser height)
<body>
<div></div>
</body>
html, body {
height: 100%;
width: 100%;
margin: 0;
}
div {
height: 100%;
width: 130vh;
margin: 0 auto;
background: #f0f;
}
However, I worry about fallback for IE8 and Safari, as it this unit is not supported there.
Are there any other CSS only methods of achieving this effect?
I have a solution that works also with IE8 (using Pure CSS 2.1), but not perfectly.
because I need the browser to recalculate things when he get resized, and apparently it doesn't do that unless he has to (and I cant find a way to make him think he has to), so you will have to refresh the page after resizing.
as far as I know, the only element that can scale reserving his ratio is an <img>, so we will use the <img> to our advantage.
SO, we are going to use an image with the ratio that we want (using the services of placehold.it), lets say we want a 13X10 ratio (like in your example), so we'll use <img src="http://placehold.it/13x10" />.
that image will have a fixed height of 100% the body, and now the width of the image scales with respect to the ratio. so the width of the image is 130% height of the body.
that image is enclosed within a div, and that div has inline-block display, so he takes exactly the size of his content. witch is the size you want.
we remove the image from the display by using visibility: hidden; (not display:none; because we need the image to take the space), and we create another absolute div, that will hold the actual content, that will be right above the image (100% width and 100% height of the common container).
That works perfectly when you first initiate the page, but when you resize the page, the browser doesn't always measure the right width and height again, so you'll need to refresh to make that happened.
Here is the complete HTML:
<div class="Scalable">
<img class="Scaler" src="http://placehold.it/13x10" />
<div class="Content"></div>
</div>
and this simple CSS:
html, body, .Content
{
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
body
{
text-align: center;
}
.Scalable
{
position: relative;
display: inline-block;
height: 100%;
}
.Scaler
{
width: auto;
height: 100%;
margin-bottom: -5px;
visibility: hidden;
}
.Content
{
position: absolute;
top: 0;
background-color: black;
}
Here's a Fiddle (don't forget to refresh after resizing)
I recommend you to copy this code to your local machine and try it there rather then within the fiddle.
In this similar SO question a CSS technique was found and explained on this blog entry that allows an element to adjust its height depending on its width. Here is a repost of the code:
HTML:
<div id="container">
<div id="dummy"></div>
<div id="element">
some text
</div>
</div>
CSS:
#container {
display: inline-block;
position: relative;
width: 50%;
}
#dummy {
margin-top: 75%; /* 4:3 aspect ratio */
}
#element {
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
background-color: silver /* show me! */
}
Demo Here
If this is sufficient for you, I'd recommend this technique. However, I'm unaware if the technique can be adapted to handle scenarios where you must have an element adjust its width depending on its height.
You can do it with the help of padding on a parent item, because relative padding (even height-wise) is based on the width of the element.
CSS:
.imageContainer {
position: relative;
width: 25%;
padding-bottom: 25%;
float: left;
height: 0;
}
img {
width: 100%;
height: 100%;
position: absolute;
left: 0;
}
I have a page with a variable-height header, content area, and footer. I want the content area to always fill the viewport, and grow vertically to fit content as necessary. I've found lots of examples of doing this with fixed-height headers, but none where the height is unknown.
Any solution needs to work in IE 6, 7 and 8, Firefox 3.x and Safari 4. Can this be done with pure CSS? Do I have to give in and resort to table-based layout?
EDIT:
An additional requirement is that I can place elements inside the content area and get them to expand to the full height of the content area (be it viewport height - header height - footer height or larger than that). Some of the content we want to display has "header" and "footer" sections of their own, so what I'm really looking for is a nestable solution.
Ok so the min-height CSS property doesn't work :)
I played around with an actual HTML file now and I believe I found a way.
.header-footer
{
height: 10%;
background-color: lightYellow;
display: table;
width: 100%;
}
.container
{
margin-left: auto;
margin-right: auto;
height: 80%;
width: 100%;
display: table;
}
.inner
{
background-color: lightPink;
height: 100%;
}
We use the display: table property to make sure each <div> sits nicely under and over the other ones.
NOTE: You have to set a height property for each of the elements on the page. It doesn't have to be as large as 10% that I chose, but at least something. Once the content is inserted into the element that is larger than the height value it should expand.
I've created two seperate HTML pages for you to examine to see if this suits you:
Content not larger than the viewport
Content larger than viewport
Hopefully this is what you're looking for.
Thanks
if you want the header to change size, use a relative height. The content will already fill the viewport vertically.
You can try using the min-height CSS property on the header, content and footer.
e.g.
.header-footer
{
min-height: 20%;
}
.content
{
min-height: 80%;
}
Make sure that you set both <html> and <body> tags to have a min-height: 100% that way you can fill up the entire viewport.
This should allow for the page to expand as needed but stay at a minimum of 100%.
Thanks
I spent a day experimenting with this option and hit so many odd dead-ends that my professional advice is now this:
You designed it wrong.
Skip the variable height header entirely. It's a dumb idea anyway. I did. Worked great for me. Now I am the proud owner of a significantly simpler DOM cobweb and no hurdles that lead me to stackoverflow.
