How to have fixed width on window resize? - html

I have a body background and I have a div in that body.On window resize, I want to have the application as such. To maintain the width,if I give fixed width to the body,on window resize I am not getting the scroll bar and as a result full page is not displayed. If I dont give fixed width, the page alignment changes and it the elements inside the body gets collapsed on window resize. Here is my code.Thanks in advance.
body.background
{
background: url(../images/common/header/Background_color.png);
background-repeat:repeat-x;
background-attachment:fixed;
background-position:top center;
height: 100%;
width: 100%;
border: 0;
background-size:contain;
position:fixed;
overflow:auto;
}
div.emptybody
{
height:100%;
width:97%;
background-color: rgb(255, 255, 255);
margin: 0px 25px 25px 25px;
height:470px;
background-position:center;
background-repeat:no-repeat;
background-attachment:fixed;
}
<body class="background">
<div class="emptybody">
-------------other elements and contents---------------
</div>
</body>

To maintain the width,if I give fixed width to the body.
You're not using a fixed width in your code, using '%' is dynamic.
On re-sizing your window it will always calculate in '%' from every border of the screen.
You need the page to 'overflow', to exceed the borders of the screen.
There are two ways of doing that:
Give your div a fixed width in pixels
div.emptybody { height: auto; width: 900px;}
Give the 'children' divs within their parent (div.emptybody) a fixed width.
div.emptybody { height: 100%; width: 97%;}
div.emptybodyChild {height: auto; width: 900px; }

try this
body {
height: 100%;
bottom: 0px;
width: 100%;
background-color: black;
}
div {
position:absolute;
height: 10px;
width: 200px;
margin:10px;
background-color: red;
}
also you can specify div posicion by providing margin-top/left/, or just using top/left/ values

You were on the right track, but you applied the overflow wrong. The overflow needs to be for the div with your content, and it needs to be set to scroll, find it here:http://jsfiddle.net/msbodetti/EWwJA/
You also gave two heights for the div. It applied the 100% height before the other height of 470px.
You can also add divs or spans within the main div to get fixed widths and heights if you need it for your content.
HTML:
<body class="background">
<div class="emptybody">
<span class="fixedText">-------------other elements and contents----------------------------other elements and contents----------------------------other elements and contents----------------------------other elements and contents----------------------------other elements and contents----------------------------other elements and contents----------------------------other elements and contents----------------------------other elements and contents----------------------------other elements and contents----------------------------other elements and contents----------------------------other elements and contents----------------------------other elements and contents----------------------------other elements and contents---------------</span>
</div>
</body>
CSS:
body.background
{
background: #000;
background-repeat:repeat-x;
background-attachment:fixed;
background-position:top center;
height: 100%;
width: 100%;
border: 0;
background-size:contain;
position:fixed;
}
div.emptybody
{
width:250px;
background-color: rgb(255, 255, 255);
margin: 0px 25px 25px 25px;
height:200px;
background-position:center;
background-repeat:no-repeat;
background-attachment:fixed;
overflow:scroll;
}

Set parent width to width of child aligned to bottom

I am trying to set the width of a div element to the width of it's longest child element, which in this case happens to be a div that I want locked to the bottom of the parent div. I am also not using a fixed height for the parent, because I do not know how big the children will need to be
Here is my html/css:
HTML:
<div id ="header-right">
<div id="content1"></div>
<div id="footer"></div>
</div>
CSS:
#header-right{
background-color: red;
position: relative;
display: inline-block;
height: 300px; /*The actual width is unknown, this is just for example*/
}
#content1{
background-color: blue;
width: 200px;
height: 100px;
}
#footer{
background-color: cyan;
position: absolute;
bottom: 0;
width: 300px; /*Also an unknown value*/
height: 25px;
}
You can have a look at this jfiddle to see what happens:
https://jsfiddle.net/rkdqp9m5/2/
You can see the container div ignores the footer, since it is absolutely positioned.
However, if I do not use absolute positioning for the footer, then I cannot lock the footer to the bottom of the div, as you can see in this jfiddle
https://jsfiddle.net/rkdqp9m5/3/
I want to lock the footer to the bottom of the container, but I also want the parent's width to be based off the footer. I do not want to use tables for this, and I do not wan to used fixed widths or heights, as the container's and the footer's dimensions will be based off of images whose widths I do not know.
Edit: I would also like to keep this strictly in HTML/CSS, if possible
If you're OK with browser requirements of flexbox, you could do:
#header-right {
background-color: red;
padding: 20px 0px 0px 0px;
height: 300px;
display: inline-flex;
flex-direction: column;
justify-content: space-between;
}
#content1 {
background-color: blue;
width: 200px;
height: 100px;
align-self: flex-start;
}
#footer {
background-color: cyan;
width: 300px;
height: 25px;
align-self: flex-end;
}
<div id="header-right">
<div id="content1"></div>
<div id="footer"></div>
</div>

Does this help: Relative parent DIV to inherit the width of absolute child DIV
What it suggests is that you can't use pure CSS, but you can use Javascript to achieve what you're trying to do.

Need to force 100% height of child DIV with z-index

I am trying to force a child DIV to 100% height within a parent DIV.
The parent div contains an image at z-index:1
The child div is z-index: 9999
I can;t get the child DIV to force 100% height.
#protect_wrap { width: 100%;
float: left;
background: #FFFFFF;
margin-top:0px;
text-align: center;
height: 100%;}
#protect_wrap img { z-index:1;}
#protect_col1 { width:200px;
margin: 0 auto;
background: yellow;
z-index:999;
position:relative;
min-height: 100%;}
img.responsive-fill { width: 100%;
float: left;
height: auto;}
<div id="protect_wrap">
<img src="img/protect.jpg" class="responsive-fill">
<div id="protect_col1"></div>
</div>
You can change #protect_col1 position to absolute and set it parent #protect_wrap to relative, the child will follow the parent height & width.
min-height is different from height. You can only min-height: 100% if the parent has some value in min-height. Can you use height for the child div?
Can you have this have these changes?
#protect_wrap {
position:relative;
.......
}
#protect_col1 {
..........
position:absolute;
}

Relative div height

I want to split up the view in four parts. A header at the top, using full page width and fixed height.
The remaining page is split up in two blocks of the same height, the upper of them contains two same-sized blocks next to each other.
What I tried is (without the header):
#wrap {
width: 100%;
height: 100%;
}
#block12 {
width: 100%;
max-height: 49%;
}
#block1,
#block2 {
width: 50%;
height: 100%;
float: left;
overflow-y: scroll;
}
#block3 {
width: 100%;
height: 49%;
overflow: auto;
/*background: blue;*/
}
.clear {
clear: both;
}
<div id="wrap">
<div id="block12">
<div id="block1"></div>
<div id="block2"></div>
<div class="clear"></div>
</div>
<div id="block3"></div>
</div>
Apparently, using a percentage value for the height won't work that way. Why is that so?
add this to you CSS:
html, body
{
height: 100%;
}
working Fiddle
when you say to wrap to be 100%, 100% of what? of its parent (body), so his parent has to have some height.
and the same goes for body, his parent his html. html parent his the viewport..
so, by setting them both to 100%, wrap can also have a percentage height.
also:
the elements have some default padding/margin, that causes them to span a little more then the height you applied to them. (causing a scroll bar)
you can use
*
{
padding: 0;
margin: 0;
}
to disable that.
Look at That Fiddle
When you set a percentage height on an element who's parent elements don't have heights set, the parent elements have a default
height: auto;
You are asking the browser to calculate a height from an undefined value. Since that would equal a null-value, the result is that the browser does nothing with the height of child elements.
Besides using a JavaScript solution you could use this deadly easy table method:
#parent3 {
display: table;
width: 100%;
}
#parent3 .between {
display: table-row;
}
#parent3 .child {
display: table-cell;
}

Example 1: Not working
Example 2: Fix height
Example 3: Table method
But: Bare in mind, that the table method only works properly in all modern Browsers and the Internet Explorer 8 and higher. As Fallback you could use JavaScript.
add this to your css:
html, body{height: 100%}
and change the max-height of #block12 to height
Explanation:
Basically #wrap was 100% height (relative measure) but when you use relative measures it looks for its parent element's measure, and it's normally undefined because it's also relative. The only element(s) being able to use a relative heights are body and or html themselves depending on the browser, the rest of the elements need a parent element with absolute height.
But be careful, it's tricky playing around with relative heights, you have to calculate properly your header's height so you can substract it from the other element's percentages.
Percentage in width works but percentage in height will not work unless you specify a specific height for any parent in the dependent loop...
See this :
percentage in height doesn’t work?
The div take the height of its parent, but since it has no content (expecpt for your divs) it will only be as height as its content.
You need to set the height of the body and html:
HTML:
<div class="block12">
<div class="block1">1</div>
<div class="block2">2</div>
</div>
<div class="block3">3</div>
CSS:
body, html {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
}
.block12 {
width: 100%;
height: 50%;
background: yellow;
overflow: auto;
}
.block1, .block2 {
width: 50%;
height: 100%;
display: inline-block;
margin-right: -4px;
background: lightgreen;
}
.block2 { background: lightgray }
.block3 {
width: 100%;
height: 50%;
background: lightblue;
}
And a JSFiddle
Basically, the problem lies in block12. for the block1/2 to take up the total height of the block12, it must have a defined height. This stack overflow post explains that in really good detail.
So setting a defined height for block12 will allow you to set a proper height. I have created an example on JSfiddle that will show you the the blocks can be floated next to one another if the block12 div is set to a standard height through out the page.
Here is an example including a header and block3 div with some content in for examples.
#header{
position:absolute;
top:0;
left:0;
width:100%;
height:20%;
}
#block12{
position:absolute;
top:20%;
width:100%;
left:0;
height:40%;
}
#block1,#block2{
float:left;
overflow-y: scroll;
text-align:center;
color:red;
width:50%;
height:100%;
}
#clear{clear:both;}
#block3{
position:absolute;
bottom:0;
color:blue;
height:40%;
}

Create three divs such that the top and bottom ones have fixed height, and the middle one has dynamic height?

I want to create three, stacked divs. The top and the bottom ones will be of fixed height, whereas the one in the middle will have a dynamic height that expands to fill the remaining space:
I've tried numerous things, such as setting the height to auto. I do have a solution, but it involves JavaScript (i.e., calculating the remaining height) but I was wondering if there was a pure CSS solution.
There's a CSS solution, but it won't work in older browsers. You need to use the calc "function" that is new to CSS, combined with height: 100%. If you've never used height: 100% before, you know that every parent element of the one you want to be 100% tall must also be set to height:100%. calc can take a percentage value and subtract pixels from it, so you just need to set it to be 100% minus however tall the top and bottom divs are.
Supported by: IE9+, Firefox 4+, Chrome 19+, Safari 6+

height: 100%;
}
#top, #bot

height: 50px;
background: red;
}
#mid
{
height: calc(100% - 100px);
}
FIDDLE: http://jsfiddle.net/jakelauer/9cYUB/
One solution is to do it with position absolute.
The downside of this approach is that if the total height of surrounding is smaller then the sum of the fixed heights the container will not be visible anymore.
Another thing to be noted is that this is probably a bad solution if you want to target mobile devices. It always depends on the exact situation if this solution is suitable.
If i remember right you will only have problems with IE 6 (on desktop) which does not support the top bottom combination for the position absolute.
HTML

You can do it with a HTML table if you need older browser support, or if you need to support IE8+ or higher you could use the CSS table layout.
Here's a jsFiddle using CSS table layout.

}
body > div {
display:table;
width: 100%;
height:100%;
}
body > div > div {

Center a button in a tiny div

I have a div with unknown height, though in this example I'm using 3px. I want to center the button but it seems to always offset by some arbitrary amount. I could do an absolute positioning trick dynamically once I know the height but I would prefer a css solution if possible.
<div style="width: 100%; height: 3px;">
<div class="special">
<input type="button" />
</div>
</div>
div{
height: 100%;
overflow: visible;
}
.special{
position:relative;
text-align: center;
padding: 1px;
border: 1px solid red;
}
input{
height: 100%;
width: 100px;
min-height: 8px;
}
The idea is that with the min-height the button will overflow evenly over the top and bottom of the div.
jsfiddle
You can get this to work by doing the following:
CSS:
div {
height: 100%;
overflow: visible;
}
.special {
text-align: center;
border: 1px solid red;
position:relative;
}
input {
position:absolute;
margin-top:-4px;
margin-bottom:-4px;
top:0px;
bottom:0px;
width:100px;
min-height:7px;
}
Note the input declaration in particular. Instead of height:100% I used position:absolute with top:0px and bottom:0px. This will set the height to 100%. It needs to be position of absolute so that you can do margin-top:-4px and margin-bottom:-4px to get the overlap. You can see that it works for any height of the outer <div/>.
The JSFiddle below has some added controls so you can change the height of the .special <div/> without needing to refresh.
