Full height sidebar over content inside a wrapper - html

I have a project using Bootstrap 3 where I need to place a sidebar over the sections with content, but respecting the width of the .container wrapper. The sidebar must fill the full page height and be scrollable.
This JSFiddle (link in comments because I can't post more than 2 links yet) shows the structure I have, with their styles. You can see the issue by playing with the height of the HTML frame on JSFiddle, making it smaller than the page height.
To better illustrate, these images show the sidebar in blue, filling all the page height, in all cases:
Case 1: the sections are taller than the viewport; the sidebar follows the body height
Case 2: the sections doesn't fill all the page, but the sidebar does
Note: it's important that the sidebar follows the width of .container. The content below doesn't, it is full width and partially visible.
Bonus: in Case 2, the section should be full height as well
I tried to give the more details I could, but I can provide any additional info.
I know it's possible through script, but I'd prefer using just CSS

It's kind of hard to help with out more details. But I went ahead and made this fiddle that has a 100% height colored background using your markup: https://jsfiddle.net/stevenng/8xdfosf6/
.container {
width: 100%;
}
.sidebar {
background: #bada55;
float: left;
width: 25%;
height: 100%;
position: absolute;
top: 0;
bottom: 0;
}
.sections {
background-color: #b000b5;
width: 75%;
height: 100%;
position: absolute;
top: 0;
bottom: 0;
right: 0;
}
Hope this helps!

How can I give full width of this element?

I have this site:
http://dl.dg-site.com/functionmentes/
There is a div with color #D9D9D9
Code CSS:
#full_bar{background:#D9D9D9;width:100%;height:100px;}
I want to my div to be the full width site and to be glued to footer.
How can i make this?
I use a theme in Wordpress.
Thanks in advance!
By making the position fixed, this will ensure that it will follow the user as they scroll up and down your website.
#full_bar {
background: #d9d9d9;
width: 100%;
height: 100px;
position: fixed;
bottom: 0;
left: 0;
}
If you add position:absolute; left: 0; to the css, the bar will more or less do what you're trying to do, but it's a dirty hack.
The real problem is that you're adding your 'full_bar' in the wrong place (inside a div which restricts the width). Personally I would opt for placing the full-bar in your <footer> tag.
You should placed your gray bar outside the section, between section and footer or on footer on html.
But if you want a css solution, you need to put your section parent to position relative and set your gray bar on absolute bottom with full width:
section {
position: relative;
padding-bottom: 100px; // Your bar height
}
#full_bar{
background:#D9D9D9;
width:100%;
height:100px;
position: absolute;
bottom: 0;
left: 0;
}
You are putting #full_bar inside class="container". container is the parent of div id #full_bar, that's why its not taking full width.
Do your code outside contaner class and you can see the changes.
See the attachment, i think you want this as per i understand your question.

Extend div height to document height

I'm trying to make extensible sidebars to the full document height without Javascript. I started to wrote some code to make this happen, but however, both div height are not extending after the viewport size.
Here is a small codepen of what is my problem http://codepen.io/anon/pen/bpAzo. As you can see, if you scroll down, height of both sidebars are just set to viewport size which is weird because i set both body, html, #sidebars to height: 100%;.
Is there a way to extend to full page height without using Javascript ?
Thank you.
You just set your sidebar height to 100% which gives it just a 100% of current browser size. Remove the height of your sidebar and remove also the html and body code.
#sidebar {
position: absolute;
top: 0;
width: 100px;
color: green;
color: #FFFFFF;
}
.left {
background-color: blue;
left: 0;
}
.right {
background-color: red;
right: 0;
}
DEMO HERE
http://codepen.io/anon/pen/jfEhH
If you set html and body to 100% height it will just be 100% of the window ( it's parent ) size. You need to set a specific height ( 3000px ) or 200% for example, which will be 2 times the windows height.
Body tag on codepen by default have margin. Without margin all looks good.
http://codepen.io/suez/pen/zJhne
But in the future, i will reccomend you to use overflow: hidden; on body (combined with margin: 0), this will provide 100% confidence that all of your content always will be inside viewport (without any scrolling).
Edited: if you want to use more than 100% of viewport height for your site, then you need to use position: fixed; on sidebar.
Just make the "height" attribute in your CSS style sheet to "auto", like as follows,
sidebar {
position: absolute;
top: 0;
height:auto;
width: 100px;
color: green;
}
Don't worry about "sidebar.right" ,as u will see no red color on right side of your page. It will automatically show up when you add up some content to it or just add few <br /> tags.

Prevent div from overflowing

I'm creating a horizontal animated page transition system where the screen scales to accomodate the incoming page. The problem I have is when moving to a smaller page size, the previous (larger) page overflows out of my content wrapper and consequently causes my overall page to extend past the footer. This screen capture shows my problem.
You can see how the current page exits on the left, after the screen has shrunk to accomodate the incoming smaller page. (the yellow is the footer, the white the unwanted screen extension).
Currently my "page" css is
.myPage
{
width: 100%;
max-width: 100%;
margin-left: auto;
margin-right: auto;
position: absolute;
top: 0;
left: 0;
display:none; /*Pages are displayed once called*/
opacity: 1;
}
I've attempted fiddling with overflow-y:hidden which I thought might work but no such luck.
What can I do to keep my page class from extending out of my content and screwing up my page?
EDIT:
Here's the page wrapper.
.pageWrapper
{
background: #FF0000;
position: relative;
width: 100%;
height: 100%;
-webkit-perspective: 1200px;
-moz-perspective: 1200px;
perspective: 1200px;
-webkit-transform: translateX(0%);
}
Edit2: A jsfiddle thats broken but features all my code
overflow-y won't work without a fixed height. Try setting the height to 100% or some other value that looks right.
In this case you could also set bottom instead of height to give the element a fixed height.

Overlapping dynamic fixed header

My fixed header is overlapping my content.
Much like here (Position fixed content overlapping problem)
but my header is dynamic so not always 50px in height sometimes 52, 100 ...
Try to position it in your box better.
When you create a fixed element, it requires an exact position:
Example:
#header{
height: 95px;
width: 640px;
position: fixed;
top: 30px;
right: 30px;
}
So, this is how your browser will read this: I will place a fixed element in the top-right corner of the screen: 30 pixels from the top, and 30 pixels from the right of my screen.
THE REASON those fixed elements are one on top of another it's because he didn't define a top/bottom and left/right position correctly. Add more text and you will see if you can scroll on the fixed elements (you can't..).
Put everything in a div and ID'it #bigBody. Give the #bigBody an exact width and height, let's say 1000 width and 600 height.
Now add these:
#header {
height: 50px;
width: 600px;
position: fixed;
top: 30px;
right: 30px;
}
#footer {
background: #fff;
bottom: 0;
right: 0;
height: 30px;
width: 600px;
position: fixed;
}
min-width is irrelevant here... you use this only if you design big websites that require multiple devices access like iPhones, Tablets etc... if your just playing with the code just stick with the basics.
You can do that via JavaScript, updating both the size of the header and the margin of other widgets. See my fiddle for an example (with CoffeeScript, tested on Firefox and Chrome), or this other fiddle that uses jQuery. Basically it's changing the CSS together for more than one element.
header { height: value + "px"; }
.contents { margin-top: anotherValue + "px"; }
If the size change isn't done by JavaScript/CoffeeScript, you'll have to put a event listener to update the .contents CSS.

Website layout advice

I'm working on a website that fits perfectly in the browser window. Below is a basic blueprint of the website layout:
So far, the Red area is just display:block. The Green area is also display:block with margin-right:200px. The Blue areas(nested in a div) is float:right.
So I've got the width sorted. It's the height I need advice on. The Red and Dark Blue areas are a set height, but I need the Green and Light Blue areas to fit the height of the browser window view.
I'm trying to use box-sizing, but it exceeds the height of the window view because it's extending to the max height of the window. Sorry for my poor explanation. Any advice if would be excellent. Thank you!
For green div set height: calc(100%-{red-div-height}); and for the light blue div set height: calc(100%-{dark-blue-div-height}-{red-div-height});
This is kinda the legacy version of C-Link's answer.
jsFiddle and fullscreen
This has the limitation of any content falling below one page-full falling outside of its container (you can see if you scroll down in the fiddle, but not on the fullscreen).
Make sure our page stretches to its full height.
body, html { height: 100%; width: 100%; margin: 0; padding: 0;}
Set a static-height header.
header {
height: 101px;
background: red;
}
Create a box for everything under the header. You were on the right track with the box-sizing. We can add padding to it, in the same amount as our header. Then percentages inside it work nicely.
.content {
position: absolute;
box-sizing: border-box;
padding-top: 111px;
padding-bottom: 10px;
top: 0; left: 0;
height: 100%; width: 100%;
}
We float our aside (may or may not be the correct element, depending on contents) and set some styles on it.
aside {
float: right;
width: 20%;
height: 100%;
padding-bottom: 111px;
box-sizing: border-box;
}
.top {
height: 100px;
background: blue;
}
.bottom {
margin-top: 10px;
height: 100%;
background: skyblue;
}
This is our main, large, content area, which we float to the left. The width could be specified exactly if we wanted exact padding at the cost of additional HTML.
[role="main"] {
width: 78%;
background: limegreen;
height: 100%;
float: left;
box-sizing: border-box;
}
You can also set overflow-y: auto on our main or aside elements, to have them scroll when they run out of space. There should also be mobile styles for this page that remove the floating, absolute positioning, absolute styling, and widths should be nearly 100%.
you can always set the green box height to the window height minus the red box height.
accordingly the light box height to the window height minus the (red box height + the dark blue box height)
Edit 1: I haven't mentioned that has to be done with javascript.
Edit 2: Consider any paddings and margins too.
Could you not just give the divs a max or min height depending on their purpose?
I use a main container or wrapper div that the others would be contained in, that div is then my effective page or screen area.
<div id="wrapper">
<div id="content">
<div id="sidebar">
</div>
</div>
</div>
#wrapper{
min-height: Whatever value you want here;
max-height: Whatever value you want here;
}
It might be a good idea to set up your page using main container divs, hot only for the content but for the header and footer as well.
As an example, I have a main wrapper that is the whole page, within that is the header div, the content div, the nav div and the footer div. These are the main ones. Everything else can then be contained within them.
So, you can set the layout out using percentages so you have a fluid design that'll react to each browser size. The other elements will then 'fit' inside the main divs and be constrained to them. You may need to look into positioning etc but this is certainly the direction you should head towards.
<div id="wrapper">
<div id="header">Header Here including any divs to be contained within this space</div>
<div id="content">All content etc here</div>
<div id="nav">This is your sidebar</div>
<div id="footer">Footer, as per header</div>
</div>
Then use the css to re deisgn the above layout focusing only on those main divs. Use % instead of px to maintain fluidity.
#wrapper{
width: 100%;
height: 100%
}
#header{
width: 100%;
height: 20%
}
#content{
width: 70%;
height: 60%;
float:left;
}
#nav{
width: 30%;
height: 60%;
float:left;
}
#footer{
width: 100%;
height: 20%
}
A pretty common trick is to give the green (and light blue) box absolute positioning, a padding AND a negative margin. Because 100% width is relative to the containing box (could be a parent div, or just the window itself) this is not suitable. When the header was a relative height, say 10%, it would've been easy. The padding makes sure the content will not disappear behind the header, the negative margin puts the box back in place. Don't forget the z-index (otherwise the content (green part) will overlap the header).
The css looks like this:
.header { position: absolute; width: 100%; height: 100px; background: red; z-index: 1; }
.content { position: absolute; width: 100%; height: 100%; padding: 100px 0 0; margin-top: -100px; background: green; z-index: 0; }
