How make a sticky header that stays in the page when zooming? - html

Here is a basic example of sticky header:
#header {
position:fixed;
background-color: #CCE;
width: 500px;
}
...
#content {
background-color: #EEE;
width: 500px;
}
The header is fixed, and the content underneath scrolls. One problem with that is that if you zoom the page (you do it often on a mobile browser), the right part of the header is no longer accessible, even if you scroll right.
Fiddle with my example here: http://jsfiddle.net/76haM/ (zoom to see it in action)
How to make a sticky header that "behaves" well on zoom?

This will not work since you specified a fixed width:
#header {
width: 500px;
}
Because of the zooming, the width of the header will be wider than the screen, causing the text to fall off.
When you have a percentage-based width, you'll get better results with the right element since the width will resize properly according to the screen:
#header {
width: 100%;
}
JSFiddle.

Footer of a web page not extending to very bottom of page

My problem is that I have a web page with a footer. I would like the page to extend the footer to the bottom of the browser window if there is not enough content to fill the entire page. I would also like the footer to go to the very bottom of the page when the content exceeds the height of the browser and there is a vertical scroll bar.
For some reason I cannot get this to work, I followed the tutorial on this page: http://matthewjamestaylor.com/blog/keeping-footers-at-the-bottom-of-the-page
and the tutorial specifically says it does what I want-
"On long pages with lots of content the footer is pushed off the visible page to the very bottom. Just like a normal website, it will come into view when you scroll all the way down. This means that the footer isn’t always taking up precious reading space."
When I follow the tutorial it successfully puts the footer on the bottom of the page when there is not enough content to fill the page, but when there is more than enough content the footer is prematurely placed where the browser window initially ends because the body's and the everything container's heights are set to the height of the window as opposed to the height of the entire page (height of page with with scrolling).
the div organization is as follows:
<div class="everything">
<div class="main_content"></div>
<div class="template_footer"></div>
</div>
My CSS code:
html, body {
margin:0;
padding:0;
height:100%;
}
.everything{ //main container
width:100%;
min-width:960px;
max-width:1450px;
margin-left:auto;
margin-right:auto;
min-height:100%;
position:relative;
}
.main_content{ //body container
width:100%;
position:relative;
float:left;
}
.template_footer{
width:100%;
height:44px;
background-color:rgba(0, 0, 0, .5);
position:absolute;
bottom:0;
}
I've also tried a bunch of different variations with height and nothing works correctly, I've searched through other questions and they don't seem to answer this problem specifically.
The footer is absolute positioned to the bottom of the .everything container.
So no matter the content, the footer will be covering the bottom 44 pixels of your container.
html {
margin: 0;
padding: 0;
height: 100%;
}
body {
min-height: 100%;
position: relative;
}
.main {
padding-bottom: 60px;
}
.footer {
position: absolute;
text-align: center;
bottom: 0;
width: 100%;
height: 60px;
}
the main section padding-bottom should be bigger than the height of the footer. The footer section has to be position absolute. The whole page should be min-height 100%.

Vertical Scroll Bars in specific DIV containers only

I'm building a page that has a list on the left, and a container showing a single item's details on the right. Here is a sample image showing the page layout and the parts I want to scroll.
In both the left container and the right container, I need to scroll when the data exceeds the container's viewport height. I only want the red-highlighted containers to scroll--the outer blue container is fixed, and the yellow portion inside the blue container is fixed. Only the red containers' contents should scroll, only when applicable.
I've put up a codepen where I'm playing around with it and can share it with you (the app itself is behind firewall, codepen is the best I can do). What you'll see on the codepen is that I can get the container to scroll when I set it's height (in this case, 380px, which is loosely about how much space is there on screen). If you move the sample codepen's container up, you'll see the scroll area stays fixed (duh), and if you increase the height of the scrollable container beyond 380px, once you go below viewport, scrolling starts to go away--at around 800px or so it completely goes away.
What the heck am I missing here? The blue containers should size themselves to the bottom of the viewport, whether it's 800px high or 1600px high. Then The red container's height would fill that available height inside the blue container, and scroll if necessary.
I'm really stumped on what I'm missing here.
Edit: jQuery and javascript sizing are not options. This is achievable by CSS only, I'm just missing some property somewhere and am stumped.
Edit 2: I tried the suggested html (html: height:100%, etc). It works in codepen, but when I attempt it on my full version of the site, it doesn't work. In the screenshot here, you can see the blue high-lighted area is the scroll container in question, and the white bar on the right is the scrollbar (custom-styled background) but no actual scroll--just the bar background.
I have implemented a basic version which should help you out.
You can find the code over at https://codepen.io/hunzaboy/pen/aWmMeJ .
Here is the CSS
body,
html {
overflow: hidden;
}
.wrapper {
display: flex;
height: 100vh;
}
.sidebar {
width: 20%;
background: blue;
color: white;
overflow-y: scroll;
}
.content {
background: yellow;
color: brown;
overflow-y: scroll;
}
with css just use overflow-y:scroll and define the max height, or just height
.that-box {
overflow-y:scroll;
height: ###px;
}
--edit: and hide the scroll bar at a certain width
#media screen and (max-width: 1024px)
{
.that-box {
overflow-y:hidden; //this will cause clipping on content outside of the box
height: ###px;
}
}
--edit2: a CSS solution
html {
min-height:100%;
position:relative }
body {
height:100%}
.box {
position:fixed;
height:100%;}
The solution I like to use is through use of the view width (vw) and view height (vh) units. Using 100 respectively for each is the equivalent of your viewport's current size.
HTML
<div class="dashboard">
<div class="left-panel v-scroll">
<!-- the stuff on your left nav -->
</div>
<div class="right-panel v-scroll">
<!-- the stuff on your right nav -->
</div>
</div>
CSS
.dashboard{
width: 100vw;
}
.left-panel{
height:100vh;
width: 20%;
float:left;
margin-left: 20px;
}
.right-panel{
height:100vh;
width: 76%;
display: flex;
}
.v-scroll{
overflow: scroll;
}
This will ensure that they will scale according to how your screen size changes.

CSS Fixing divs in place and hiding overflows

So, I've been stuck with this problem for a while now and I can't seem to find a solution.
I'm trying to make a layout consisting of (for now) 4 different content areas like so:
What I'm trying to do
I'm trying to do the following things:
Simple explanation: Content should be the only scrollable thing on the page, with the footer following right behind it if content fits on the page, fixed on the bottom otherwise.
Detailed explanation:
Fix banner and mainMenu so that they never move when page is scrolled.
Make the content scroll with a page so that:
If the content (and footer) fit on a page, no scroll is displayed.
If the scroll is needed, content goes behind the banner (not being shown) and does not appear again above it.
If the scroll is needed, content can scroll until the bottom line of it and the footer are in the visible area.
The footer should do two things:
If content and footer fit on the page, footer should stick at the bottom of the content
Otherwise, footer should be fixed on the bottom.
What I have tried
Fixing banner,mainMenu and the footer are fixed using position: fixed (and positioned accordingly). Parent div has overflow: hidden (which doesn't seem to work).
<div id='main'>
<div id='banner'>banner</div>
<div id='mainMenu'>mainMenu</div>
<div id='content'>.. some long content ..</div>
<div id='footer'>footer</div>
</div>
And
#main {
width: 960px;
height: auto;
margin: 40px auto;
overflow: hidden;
}
#main #banner {
width: 960px;
height: 100px;
position: fixed;
}
#main #mainMenu {
width: 230px;
height: auto;
display: inline;
float: left;
position: fixed;
top: 140px;
}
#main #content {
width: 720px;
height: auto;
display: inline;
float: right;
margin-top: 100px;
}
#main #footer {
width: 960px;
height: auto;
clear: both;
position: fixed;
bottom: 0;
}
The Problem
Footer does not follow content if it fits within the area
Content overflows on the top of banner
I would really prefer to do this just in CSS (if possible) and as compatible as possible (IE7+, all other major browsers).
It's really getting frustrating now.. Any help would be appreciated.
There is no conceivable way I can think of that would solve your problem by just using css. Once you have set your elements to a fixed position they are out of the flow and thus your other elements cannot conform around them.
However I did find a solution by doing two different things. For the header issue I simply added another fixed element above the main banner and set it to the color of the background. This way the content will scroll behind it and look as if it is hidden. For the footer, I set up some javascript using jQuery to see if the content overflows or not. If it does then the footer's position is set to fixed, otherwise the position is set to relative.
You can check it all out here in this demo: http://jsfiddle.net/mrQGh/4/
To test out the javascript simply delete the text until there is no more overflow and run it again.

Footer Background image shrinks when changing width of window

I have a footer i created for a website, but for some reason when i change the width of the window the background image seems to just disappear throughout the right side as i'm shrinking the width of the window.
The footer is supposed to stretch 100% accross the bottom of the screen and does so until i start shrinking the width of the window to a certain point.
You can see an example of my issue Here
Any ideas how to fix this? I am totally stumped. Maybe i did something wrong with width?
The width of #footer is set to auto, and the content within (#content-wrapper) has a fixed width.
This is causing the horizontal bars to appear.
To solve this, you can set overflow:hidden to the parent div (#footer).
Try this:
#footer {
background-image: url("images/footer-bg.png");
background-repeat: repeat-x;
height: 451px;
margin: auto 0;
width: 100%;
overflow: hidden; //What you're looking for.
}
If you also want the inner div (#content-wrapper) to dynamically resize itself, use a percentage, instead of a pixel dimension for width:
#footer #content-wrapper {
height: 451px;
margin: auto;
width: 83%;
}
Hi i have check to your demo page you have define your footer width 1265px and now
than your define min width your html or body as like this
body, html {
min-width: 1265px;
}
because your max width is 1265 define to your footer so that you define same width your body or html

Centering a position: fixed div When Viewport Reaches a Designated Width

I am looking to create a layout for my site where a sidebar is fixed at the right side of the viewport with a 30% width (content is to the left of it) until the browser window reaches a certain width, at which point I want the content and sidebar to be centred and no longer grow with the browser window (since it becomes hard to read at extremely large widths). Here is an idea of the html being used:
<body>
<div id=sidebar>sidebar content</div>
<div id=content>articles, images, etc</div>
And here is some of the basic HTML being used to format it:
#sidebar {
width: 30%;
position: fixed;
right: 0;
top: 0;
background-color: gray;
}
#content {
width: 70%;
margin-right: 30%;
max-width: 49em;
}
At this point, when the content gets wider than 49em, it sticks to the right side of the page creating an ever-increasing gap between it and the fixed sidebar. What I would like is to have it reach a max width of 49em, have the sidebar reach 21em (so they are still 70:30) and remain fixed, but have that whole 70em worth of width centered in the viewport.
I also want the background colour of the sidebar to span the entire way from the edge of the content to the right-hand side of the screen (i.e. a containing div that centers both the sidebar and content with a max width of 70em doesn't work since the background of the sidebar would only go to the edge of the containing div instead of the viewport). That one isn't as important because it might look fine to put some sort of textured background on the body element to make it look like as though the page is "sitting" on some textured surface (not ideal, but fine). I just haven't been able to center the sidebar and content while maintaining the sidebar's fixed positioning.
Thanks!
Update: here's a very rough schematic of what I am looking for:
|A|B|C|D|
B is the content area with a max width of 49em. C is the sidebar with max width of 21em AND it has to have fixed positioning. A and D would be the margins (each half of the difference between the viewport width and 70em). Background of D must be the same colour (gray) as the sidebar. Background of A must be white.
This solution meets most of your requirements, but you need to provide the width of the content+sidebar (in this case, I put 70em)
HTML:
<div id="container">
<div id="content">articles, images, etc</div>
<div id="sidebar">sidebar content</div>
</div>
CSS:
#sidebar {
width: 29%; background-color: gray; border: 1px gold solid;
float: left;
position: fixed; right: 0; top: 0;
}
#content {
width: 69%; max-width: 49em; border: 1px silver solid;
float: left;
}
#container {
max-width: 70em;
margin: 0px auto;
}​
jsFiddle here. (You can test by just dragging the middle frame left and right)
​
Something like this:
<body>
<div id="wrapper">
<div id="sidebar">sidebar content</div>
<div id="content">articles, images, etc</div>
</div>
</body>
With CSS that is similar to this:
body { background:url(imageForSidebar.png) right top repeat-y; }
#wrapper {
max-width:1000px;
margin:0 auto;
background:#FFF url(imageForSidebar.png) -66% top repeat-y;
position:relative;
}
#sidebar {
width:30%;
float:right;
position: fixed;
}
#content { margin-right:30%; }
The background image on the body would take care of it going all the way to the edge of the screen. You would use a background image that was large enough to do this, but small enough so that it gets covered by the #wrapper background. The background image on the wrapper works in a similar way, but in this case it is just making sure that the sidebar image always extends to the bottom of the content.
You can add media queries into your css
//your normal css
#sidebar {
width: 30%;
position: fixed;
right: 0;
top: 0;
background-color: gray;}
//media query (you can add max and min width of the sceen or one of both)
#media screen and (min-width:500px) {
#sidebar{
//css you want to apply when when width is changed
}
}
