On my site I am using the theme Newspaper. I have modified it a bit with css. I am trying to get my sidebar (instagram, most popular, newsletter sign up) to have a width of 26% so it would be on the same row as the editor's picks.
The problem is that I can not get the sidebar to have a width of 26% without affecting the 3 blocks above editor's picks. Since both of them are .td-pb-span4. I have tried to solve this issue by using a more specific code just for the sidebar (code down below) and it still will not work. It is weird because the code I am trying to use will apply in chrome developer, however once I add it to my css it doesn't apply to my site. I would really appreciate any solution, I have been trying to figure this out for a few days and can't seem to find the problem.
code I first tried to add but it affected both the sidebar and the 3 blocks above editors picks (and I only want width:26% to apply to the sidebar)
.td-pb-span4 {
width: 26%;
}
more specific code I am trying to add that only applies to the sidebar (it will work in chrome developer, but will not work if I apply it to my site css)
.vc_column.td_uid_70_5976097f07941_rand.wpb_column.vc_column_container.td-pb-span4 {
width: 26%;
}
Don't do this:
/* index ~line 2817 */
.td-pb-span8 { /* WHY */
width: 70%;
float: left;
margin-right: 4%;
}
you're touching a well defined grid system that has to work out of the box:
.td-pb-span8 {
width: 66.66666667%; /* yep. There's no reason on earth you should set to 70% */
}
Grids are 12 based so do the math: 100 / 12 * 8

I would like to use media queries to resize elements based on the size of a div element they are in. I cannot use the screen size as the div is just used like a widget within the webpage, and its size can vary.
Yes, CSS Container Queries are what you're looking for. The CSS Containment Module is the specification that details this feature.
You can read more about the decade of work, including proposals, proofs-of-concept, discussions and other contributions by the broader web developer community here! For more details on how such a feature might work and be used, check out Miriam Suzanne's extensive explainer.
Currently only Chromium 105+ supports Container queries out of the box, though Safari 16 will include support as well. Hopefully it won't be much longer before we see a robust cross-browser implementation of such a system. It's been a grueling wait, but I'm glad that it's no longer something we simply have to accept as an insurmountable limitation of CSS due to cyclic dependencies or infinite loops or what have you (these are still a potential issue in some aspects of the proposed design, but I have faith that the CSSWG will find a way).
Media queries aren't designed to work based on elements in a page. They are designed to work based on devices or media types (hence why they are called media queries). width, height, and other dimension-based media features all refer to the dimensions of either the viewport or the device's screen in screen-based media. They cannot be used to refer to a certain element on a page.
If you need to apply styles depending on the size of a certain div element on your page, you'll have to use JavaScript to observe changes in the size of that div element instead of media queries.
Alternatively, with more modern layout techniques introduced since the original publication of this answer such as flexbox and standards such as custom properties, you may not need media or element queries after all. Djave provides an example.
I've just created a javascript shim to achieve this goal. Take a look if you want, it's a proof-of-concept, but take care: it's a early version and still needs some work.

From a layout perspective, it is possible using modern techniques.
Its made up (I believe) by Heydon Pickering. He details the process here: http://www.heydonworks.com/article/the-flexbox-holy-albatross
Chris Coyier picks it up and works through a demo of it here: https://css-tricks.com/putting-the-flexbox-albatross-to-real-use/
To restate the issue, below we see 3 of the same component, each made up of three orange divs labelled a, b and c.
The second two's blocks display vertically, because they are limited on horizontal room, while the top components 3 blocks are laid out horizontally.
It uses the flex-basis CSS property and CSS Variables to create this effect.
.panel{
display: flex;
flex-wrap: wrap;
border: 1px solid #f00;
$breakpoint: 600px;
--multiplier: calc( #{$breakpoint} - 100%);
.element{
min-width: 33%;
max-width: 100%;
flex-grow: 1;
flex-basis: calc( var(--multiplier) * 999 );
}
}
Demo
Heydon's article is 1000 words explaining it in detail, and I'd highly recommend reading it.
Update 2021/22
As mentioned in other answers, container queries are coming. There is a full spec for it, and its usage is detailed on MDN:
https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Container_Queries
and there is a polyfill to get browsers that don't yet support it up to speed:
https://github.com/GoogleChromeLabs/container-query-polyfill
There is a nice little overview video of it here:
https://www.youtube.com/watch?v=gCNMyYr7F6w
This has now shipped to Chrome (05 September 2022)

A Media Query inside of an iframe can function as an element query. I've successfully implement this. The idea came from a recent post about Responsive Ads by Zurb. No Javascript!
This is currently not possible with CSS alone as #BoltClock wrote in the accepted answer, but you can work around that by using JavaScript.
I created a container query (aka element query) polyfill to solve this kind of issue. It works a bit different than other scripts, so you don’t have to edit the HTML code of your elements. All you have to do is include the script and use it in your CSS like so:
.element:container(width > 99px) {
/* If its container is at least 100px wide */
}

I ran into the same problem a couple of years ago and funded the development of a plugin to help me in my work. I've released the plugin as open-source so others can benefit from it as well, and you can grab it on Github: https://github.com/eqcss/eqcss
There are a few ways we could apply different responsive styles based on what we can know about an element on the page. Here are a few element queries that the EQCSS plugin will let you write in CSS:
#element 'div' and (condition) {
$this {
/* Do something to the 'div' that meets the condition */
}
.other {
/* Also apply this CSS to .other when 'div' meets this condition */
}
}
So what conditions are supported for responsive styles with EQCSS?
Weight Queries
min-width in px
min-width in %
max-width in px
max-width in %
Height Queries
min-height in px
min-height in %
max-height in px
max-height in %
Count Queries
min-characters
max-characters
min-lines
max-lines
min-children
max-children
Special Selectors
Inside EQCSS element queries you can also use three special selectors that allow you to more specifically apply your styles:
$this (the element(s) matching the query)
$parent (the parent element(s) of the element(s) matching the query)
$root (the root element of the document, <html>)
Element queries allow you to compose your layout out of individually responsive design modules, each with a bit of 'self-awareness' of how they are being displayed on the page.
With EQCSS you can design one widget to look good from 150px wide all the way up to 1000px wide, then you can confidently drop that widget into any sidebar in any page using any template (on any site) and
The question is very vague. As BoltClock says, media queries only know the dimensions of the device. However, you can use media queries in combination with descender selectors to perform adjustments.
.wide_container { width: 50em }
.narrow_container { width: 20em }
.my_element { border: 1px solid }
#media (max-width: 30em) {
.wide_container .my_element {
color: blue;
}
.narrow_container .my_element {
color: red;
}
}
#media (max-width: 50em) {
.wide_container .my_element {
color: orange;
}
.narrow_container .my_element {
color: green;
}
}
The only other solution requires JS.
The only way I can think that you can accomplish what you want purely with css, is to use a fluid container for your widget. If your container's width is a percentage of the screen then you can use media queries to style depending on your container's width, as you will now know for each screen's dimensions what is your container's dimensions. For example, let's say you decide to make your container's 50% of the screen width. Then for a screen width of 1200px you know that your container is 600px
.myContainer {
width: 50%;
}
/* you know know that your container is 600px
* so you style accordingly
*/
#media (max-width: 1200px) {
/* your css for 600px container */
}
You can use the ResizeObserver API. It's still in it's early days so it's not supported by all browsers yet (but there's several polyfills that can help you with that).
This API allows you to attach an event listener when resizing a DOM element.
Demo 1 - Demo 2
I was also thinking of media queries, but then I found this:
http://www.mademyday.de/css-height-equals-width-with-pure-css.html
Maintain the aspect ratio of a div with CSS
Just create a wrapper <div> with a percentage value for padding-bottom, like this:
div {
width: 100%;
padding-bottom: 75%;
background:gold; /** <-- For the demo **/
}
<div></div>
It will result in a <div> with height equal to 75% of the width of its container (a 4:3 aspect ratio).
This technique can also be coupled with media queries and a bit of ad hoc knowledge about page layout for even more finer-grained control.
It's enough for my needs. Which might be enough for your needs too.
For mine I did it by setting the div's max width, hence for small widget won't get affected and the large widget is resized due to the max-width style.
// assuming your widget class is "widget"
.widget {
max-width: 100%;
height: auto;
}
I'm looking for a simple, effective and modern way to implement the following layout for a website:
- header: 100% width
- below header
- sidebar with fixed width
- content area that fills up till 100%
I've found a good example here, but this is all based on 'em' sizing, we have quite some backgroundpixels so we rather need an example with 'px'.
We thought that we could switch easily to 'px' in that specific example, but apparently it's not that easy to get this perfect.
Thanks in advance for all the tips!
You can use flex to have a sidebar on the left with a fixed width whereas the content on the right takes up the remaining space. Be aware that flex was added with CSS3 and older versions of Internet explorer may not support it (http://caniuse.com/#search=flex)
.contentContainer {
display:flex;
flex-direction: row;
}
.left {
background-color: #ffaa00;
min-width:200px;
}
.right {
background-color: #00aaaa;
flex:1;
}
https://jsfiddle.net/nrv5p70q/1/
However some simple googling could have solved the issue too. You may want to check this cheat sheet:
https://css-tricks.com/snippets/css/a-guide-to-flexbox/
The example you are using will allow you to achieve this.
You can use a em to px conversion to convert the values from em to px. Once you have the correct values you can replace them in the css. Thus.
#nav {
margin-left: -352px; //was -22em
margin-left: expression((-(document.getElementById("wrapper").clientWidth))+"px");
left: 208px; //was 13em;
}
Using this method will allow you to continuing w3schools tutorial which is a great way to get up to speed with html and css.
I'm trying to customize a Joomla template, which is based on Bootstrap. Specifically, I'm trying to make a "hardcoded" .span4 have the width of a .span3. Sure, it would be much easier to change the markup, but I think that's what css is for, despite the way most of us use Bootstrap for defining layout and visual appearance. Besides, where would be the fun of learning?
For that, this is what I'm trying in the my_css.less provided with the template:
.row-fluid #top1.span4 {
.row-fluid .span(3);
background:red;
}
Actually, the "background" bit is only to make sure that I'm not getting the selector wrong. So, I get that element with a red background, but the rest of the properties aren't applied. This is what I get instead:
.row-fluid .span4 {
width: 31.623931623932%;
}
Am I doing anything wrong? Is what I'm trying even possible?
Thank you!
* Edit *
This is the template I'm using in my page:
Perty by SmartAddons
The bit I'm trying to customize is the one at the right of the logo, the one holding the language selector and the social icons.
My client's logo is wider than the one in the template example, so it pushes #top1 to the right, and it pushes the following element (the one containing "galleries", "my account" and the search box) below.
Answering #Harry's question about selectors not matching, mine is ".row-fluid #top1.span4" because I only want my modification to apply to the .span4 contained in #top1. The other piece of code I pasted below is what is being applied instead of what I intend. Also, I wanted my customization to take preference over the default css, so my selector tries to be more specific. It doesn't seem to be wrong, because the background of the element becomes red.
#Harry:
Also, are you using any mixins to generate the width?
I'm not experienced in Less and I wasn't able to find the mixin in bootstrap documentation, but according to #freejosh at this post:
In mixins.less there's a mixin called .span(#columns) that's used to calculate the width, depending on #gridColumnWidth and #gridGutterWidth along with the argument.
Actually, that example is the one I'm trying to adapt to my needs.
I hope my edition made things clearer (or at least not more obscure, english is not my native language).
Thank you again!
* Edit 03/09/2014 *
Ok, I think I'm gettin closer. New code:
.row-fluid #top1.span4 {
#grid > .fluid > .span(3);
background:red;
}
Resulting css:
.row-fluid #top1.span4 {
width: * 3 * 2;
background: red;
}
Of course, the browser complains of an invalid property value. But at least that is a step (forward?)
#grid > .fluid > .span(3);
gives me:
.row-fluid #top1.span4 {
width: 23.40425532%;
*width: 23.35106383%;
background: red;
}
and NOT width: * 3 * 2;
Tested with less.php, less v1.4, v1.7.3. Notice that Less v2 do not compile BS2 at all.
Less v2 fails on #grid > .core > .span(#gridColumns); in navbar.less
tldr: I want to create simple theme, based on 2 columns with just pictures, that fill the whole screen, like this - http://half-way.precrafted.com/
Hello.
I started learning html/css yesterday, because i want to create rather simple theme that would fit my needs.
However, it turned out to be harder than i thought, unfortunately.
I post only pictures, without any captions or tags. All i want is theme based on 2 grids, where whole screen is occupied with pictures (except header on top). This is the best, almost exact example of what i want - http://half-way.precrafted.com/
However, the issue is that tumblr allows photoset with maximum width of 700px. This may be overriden with javascript - and i found such scripts, but it uses fixed values, so it won't really fit to any screen - just mine.
Set the photosetrow class to:
<div class="photoset_row photoset_row_2">
The CSS for this:
width: 400px;
white-space: nowrap;
overflow: hidden;
margin-top: 10px;
.photoset .photoset_row .photoset_photo:first-child {
margin-left: 0 !important;
}
.photoset .photoset_row .photoset_photo {
display: inline-block;
vertical-align: top;
margin-left: 10px;
}
I literally pulled that CSS from looking at the source code of that page you posted.
It seems the most important one is the photoset_row_2
Here's a fantastic CSS menu:
The only disadvantage its not stretched to 100%... if it has 2 elements, it should be 50%/50%, if 4 items then 25%/25%/25%/25% just like they were table cells. How to do that? I'm new to CSS.
Use display: table/table-cell (for modern browsers and IE8+) and display-table.htc (for IE6/7).
Modify its width as 100% will make the menu span to full width.
#myfantasticmenu { width: 100%; }
I simulated the change with firebug and the needed Style defination was
#nav {
overflow: hidden; /* To clear the div */
width: 100%;
}
And about the part, where you need 50/50 for two and 25 each when the item are 4, you will require some javascript to do so.
If you consider using jQuery then it will something like
childs= $("#myfantasticmenu").children('a'); //grab the list items
childs.css('width', (100/childs.length)+%);
If avoiding scripting is your MAJOR target, then bring tables into the games, they automatically do the behavior you need.
