Let's say I have a CSS DIV that holds formatted syntax code. The DIV is set to a min-width:100; and a max-width:100;
This same DIV has another CSS declaration for when the DIV is Hovered, max-width: 135% !important; and min-width: 135%;
So if the DIV holding the formated code is wider then the DIV's width, it shows a scroll bar and when you hover over the DIV it expands the DIV to the width of the code not to exceed 135%, if the DIV's code does not exceed the width of the DIV then the DIV stays the same width.
My problem, is that when a div exceeds the 100% width, it expands to the width of the code inside but stays LESS then 135%, is there a way to make it expand to 135% even if the code is not 135% but is over 100%?
Hopefully this makes sense
I almost need some kind of conditional statement that says...
If DIV contents are > 100% then make DIV 135% on Hover otherwise leave DIV at 100%
Is this even possible?
Here is my full CSS
.syntax {
min-width: 100%;
max-width: 100%;
margin: 1em 0 1em 0;
position: relative;
overflow-y: hidden;
overflow-x: auto;
font-size: .9em;
display:inline-block;
}
.syntax:hover {
max-width: 135% !important;
min-width: 135%;
}
I'm not sure I'm getting waht you mean, but if I'm not mistaken, all you're leaving aside is this:
min-width: 135% !important;
you may need to adjust overflow depending on what you need
A better option would be to use fixed sizes, but if you're working on adaptive layout environments guess that is a no go

I have a layout like this one. I need the green element to be always centered, whatever the screen size. It works, unless the scrollbar appears.
I've seen in chrome there is 'overflow-y: overlay' css attribute, but I can't find a way to reproduce the same behaviour on other browsers, unless with some javascript (which I would like to avoid for something like this)
IMPORTANT: always hiding or showing the scrollbar is not an option!
Is there a way to achieve the wanted result?
I've just created a fiddle for this. Just remove padding from .body and set width as 100% - padding, like I did.
If you don't want only green div to be scrollable, just move overflow-y: auto; to .container
.container .body {
overflow-y: auto;
max-height: 300px;
width: calc(100% - 200px);
margin-left: auto;
margin-right: auto;
}
I am trying to set the width of the .full_height_div element using pure css, based on its height. It has to be width-relative-to-height, and not height-relative-to-width. The reason for this is that the parent container (.set_rectangle_height) is already a div with height relative to the page width. Obviously, as the page is resized the divs on the page will resize, so i cannot set a fixed width in px for the .full_height_div child.
So .rectangle and .set_rectangle_height make up the parent container which has a width as a percentage of the page and a height relative to this width. See here for an explanation for this method.
But the problem is that then I want to place a div inside the parent with height: 100% and width relative to this height. The aim is then that I will be able to alter the browser window size and everything will keep its aspect ratio.
here is my failed attempt:
.rectangle
{
position: relative;
width: 30%;/*the outermost div is always a % of the page
width, even while resizing*/
display:inline-block;
background-color: green;
}
.set_rectangle_height
{
padding-bottom: 30%;/*this sets the height of the outermost div
to a ratio of 1:3*/
position: relative;
float: left;
width: 100%;
height: 100%;
}
.full_height_div/*this is the div that i want to have a width relative
to its height*/
{
height: 100%;
width: 20px;/*i will delete this once .square_set_width is working*/
position: absolute;
background-color: red;
}
.square_set_width
{
display: inline-block;
padding-left: 100%; /*i want to use something like this line to set
the width of this div to be equal to .full_height_div's height - ie a 1:1 aspect
ratio, but padding-left does not work :( */
position: relative;
height: 100%;
background-color: blue;
}
<div class='rectangle'>
<div class='set_rectangle_height'>
<div class='full_height_div'>
<div class='square_set_width'></div>
</div>
</div>
</div>
So, this is what the above incorrect markup looks like:
And this is what i want it to look like:
I know I could find the blue square percentage height in javascript, then set the width to be equal to this height, but it would be really handy if there is a pure css fix for what I am trying to do. I will be using this structure a lot and I don't really want to go writing code to resize all the divs on my page.
you have to use javascript for that. If I understood you, you want a perfect blue square. Use
var height = $('.square_set_width').height();
$('.square_set_width').css('width',height);
here is a jsfiddle: http://jsfiddle.net/a8kxu/
Edit: instead of doing padding-bottom: 30% do height: 70% instead. Here is another fiddle: http://jsfiddle.net/a8kxu/1/
Edit #2: Sorry, but you cant use css to do this. Its not powerful enough
If i understand you correctly
you can do
#divID {
width: 75%;
margin-left: auto; // this is used to center the container
margin-right: auto;// this as well
}
I've created a really simple modal that allows the content to decrease or expand without running off the page - always leaving 10% margin on the top and bottom. When the page isn't tall enough to contain all the modal content, the entire modal becomes scrollable.
See jsfiddle here
Is it possible, using only CSS, to replicate this behavior but only have the modal body be scrollable, so the header is always fixed. I've tried a few things, but haven't come up with the solution yet. Making the header position: fixed almost works, I have to reposition it over the modal box and then try to add padding to the body so the content is visible under the header, which doesn't budge the scrollbars down. I always prefer to exhaust all the css alternatives before I bind some js to window resize and manually manipulate the body height.
This might be late, but I had to solve a similar issue of fixed header, fluid height, fluid width.
This is how I tackled the issue:
Give your elements a border-box box-sizing. Use a wrapper to center and create a bounding box. This can be a fluid one with min-width and max-width + percentages.
Give your content element an overflow-y of auto and a max-height of 100%;
Use box-sizing:border-box;
The complete code should be something like this:
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
.modal {
position: fixed;
width: 100%;
height: 100%;
background-color: rgba(0,0,0,0.8);
}
.wrap {
position: relative;
margin: 0 auto;
display: block;
width: 90%;
/* Change the max-width value on a media query breakpoint to make this example more "responsive" */
max-width: 500px;
height: 90%;
padding: 30px;
}
.modal header {
height: 30px;
padding: 0;
color: #FFF;
background-color: #007;
}
.modal .body {
background-color: #FFF;
max-height: 100%;
overflow-y: auto;
}

Applying the max-height and overflow-y settings to .body rather than to .wrap...?
Edit 1:
Nothing's turned up so far within the constraints, which suggests either JavaScript or straying from the constraints (using % for the header height or px margins).
Edit 2:
Here's an initial demo using % for the header height. I added a px min-height to the header tag to prevent the header from almost disappearing on very small screens, at the expense of the top margin (which is reduced on very small screens).
On a screen >= 400px tall, it should work exactly as per the requirements (40px header with 10% height). If the header were reduced in height, it would support slightly-smaller screens (a 30px header with 10% height would support >= 300px screens). Here's a demo with a 30px header.
It's a clumsy solution, but it's the only one that turned up without using JavaScript.
Also, note that I added an h2 and a .content tag and moved the padding:10px; there, to avoid combining % height and padding in the same elements (which leads to a taller height than the % value specified).
Id like to know why my inner wrap of the desktop css for this site is not working.
Basically if set innerwrap to margin:0 auto; and width: auto; there is no problem, but it's not centered on the footer or main div
When I have innerwrap as it's currently set margin:0 auto; and width:960px; you'll notice that the page presents a horizontal scroll bar after resizing the window a bit, and all the content is squished to the left with a white background starting to become visible.
Is there anyway to have it transition fluidly to the next tablet size layout without have a scroll bar appearing and content getting squished?
It shows Scrollbar because of the padding you apply in .innerwrap
Read this article about the Box Model
Use of padding on the sides of certain elements when applying 100% width to parent element its not recommendable because it adds width to the whole group, and since you,re using the browsers width it shows the scrollber to see the extra space you added.
My humble advice is that if you want a block element to appear centered apply an margin:auto style rule whenever is possible, the same also has to be displayed as a block element with no float.
Remove this:
.innerwrap {
margin-left: auto;
margin-right: auto;
padding-left: 10%;
padding-right: 10%;
width: 80%;
}
Keep This
.innerwrap {
margin: auto;
width: 960px;
}
Since you are applying fixed margins for you social icons they will show misplaced, so don't use fixed margins for centering them, use percentage width instead.
you may want use a common class for aligning them
.social {
background-position: center center;
background-repeat: no-repeat;
display: block !important;
float: none;
height: 150px;
margin: auto;
padding-top: 50px;
width: 30% !important;
}
For a.twittersocial and a.twittersocial:hover and the rest of the social links just keep the background properties.
Create a determined class if you need to apply common style rules to several elements (if there are many of them) and avoid usage of ID selectors whenever is possible, use classes instead (.daclass).
Use a web inspector like Firebug to track down styling errors.
Good luck Developer!
I'm trying to build a quick overview that shows the upcoming calendar week. I want it arranged horizontally so it can turn out to be quite wide if we show a full calendar week.
I've got it set up right now with an inner div with a fixed width (so that the floated "day" divs don't return below) and an outer div that's set to width: 100%. I'd LIKE for the outer div to scroll horizontally if the page is resized so that the inner div no longer fits in it, but instead the outer div is fixed larger at the width of the inner div and the page itself scrolls.
Gah I'm not good at explaining these things... Here's a bit of code that might clear it up..
The CSS:
.cal_scroller {
padding: 0;
overflow: auto;
width: 100%;
}
.cal_container {
width: 935px;
}
.day {
border: 1px solid #999;
width: 175px;
height: 200px;
margin: 10px;
float: left;
}
and the (simplified) structure:
<div class="cal_scroller">
<div class="cal_container">
<div class="day">Monday</div>
<div class="day">Tuesday</div>
<div class="day">Wednesday</div>
<div class="day">Thursday</div>
<div class="day">Friday</div>
</div>
</div>
So to try again - I'd like the cal_scroller div always be the page width, but if the browser is resized so that the cal_container doesn't fit anymore I want it to scroll WITHIN the container. I can make it all work if I set a fixed width on cal_scroller but that's obviously not the behavior I'm going for. I'd rather not use any javascript cheats to adjust the width of the div if I don't have to.
Your cal_scroller class is 100% + 20px (padding) wide. Use a margin on cal_container instead, like so:
.cal_scroller {
padding: 10px 0;
overflow: auto;
width: 100%;
}
.cal_container {
margin: 0 10px;
width: 935px;
}
See here for a description of how the box model works (in short, the everything is outside the width/height of an element).
Also, block elements (like <div>s) are 100% width by default, making your 100% width declaration redundant.
One problem I see is your width: 100% rule. div.cal_scroller is already a block-level element, so it'll default to filling the entire page width. (Not to mention that padding is added on top of width, so you end up with that div being bigger than the page.)
Just get rid of that width rule, and you should be golden. (I just tried myself, and it worked like a charm.)
I didn't read your question very carefully, but when you have width: 100% and padding, that's generally not what you want.
100% + 20px > 100% - that might be the problem.
I struggled with this a lot but the simplest solution I found was adding:
.cal_container { white-space: nowrap; }
This way you don't have to give it a width at al. It just makes sure everything stays in one line.
