I know there are a ton of answers on :hover effecting other classes. What I'm trying to do is change the font color of itself (.footer_status_tex) and background-color of another class (.footer_status_gear)
Simplified CSS - Something like this:
CSS
.footer_status_tex {
cursor: pointer;
color: #fff;
}
.footer_status_gear {
width: 36px;
height: 36px;
background-color: #000;
}
.footer_status_tex: hover {
color: #81aaf3;
}
.footer_status_tex:hover .footer_status_gear {
background-color: #aba51e;
}
HTML
<div class="footer_status_tex" style="">Hello</div>
<div class="footer_status_gear"></div>
Current setup only changes font color.
Thanks
First, you need to fix the selector .footer_status_tex: hover, remove the gap after :.
Second, the selector .footer_status_tex:hover .footer_status_gear only works if the latter one is a child of the former one.
What you need is .footer_status_tex:hover + .footer_status_gear or ~ if the latter one is a sibling of the former one, also the latter one must be placed next to the former one in the DOM.
.footer_status_tex:hover {
color: #81aaf3;
}
.footer_status_tex:hover + .footer_status_gear {
background-color: #aba51e;
height: 20px;
}
<div class="footer_status_tex">Hello</div>
<div class="footer_status_gear"></div>
You can use ~ adjacent selector to target the adjacent elements
Stack Snippet
.footer_status_tex {
cursor: pointer;
color: #fff;
}
.footer_status_gear {
width: 36px;
height: 36px;
background-color: #000;
}
.footer_status_tex:hover {
color: #81aaf3;
}
.footer_status_tex:hover ~ .footer_status_gear {
background-color: #aba51e;
}
<div class="footer_status_tex" style="">Hello</div>
<div class="footer_status_gear"></div>
When posting CSS problems, please also include the associated HTML code as without it, we're can only assess half the problem.
I'm assuming this is your structure: https://codepen.io/barrymcgee/pen/vdGOra?editors=1100#
The reason why the background of .footer_status_gear doesn't change is because it's the parent element of the link. A :hover pseudo-class can only direct the children of the element to which it is applied.
If the assumption I made about your HTML structure is wrong, please provide it and I'll look again.

Presentation
I'm trying to build a web site available in multiple cultures, with different reading direction.
To do so, I simply add the dir="rtl" attribute on my root HTML element.
My issue is that I have some CSS rules that are specific to one direction or the other (margins or paddings, most of the times).
Unsuccessful try with attribute selector
I though that I could simply use the attribute selector but the dir attribute is only set on the root element, so this wouldn't work :
selector {
&[dir="ltr"] {
// LTR specific
}
&[dir="rtl"] {
// RTL specific
}
}
For instance, on this demo, the title should have a margin of 5px on the right if the application is in rtl or on the left if it's in standard ltr.
Other idea
I've noticed that the direction is rightfully set at rtl, is there a way to use that rule within a CSS or Sass selector ?
Edit and precisions
It seems that I've forgotten an important point. I'm building the web site using Vue.js, the dir attribute is bind in the main component (App) and the RTL/LTR specific CSS rules can be in the same component or in other self-contained component.
Following your css code you could do this with SASS at-root directive DEMO. So this:
#app {
width: 300px;
height: 100px;
border: 1px solid red;
h1 {
#at-root {
[dir="rtl"]#{&} {color: green}
}
#at-root {
[dir="ltr"]#{&} {color: red}
}
}
}
It will compile to this css.
#app {
width: 300px;
height: 100px;
border: 1px solid red;
}
[dir="rtl"]#app h1 {
color: green;
}
[dir="ltr"]#app h1 {
color: red;
}
You could style everything LTR, and only adjust some elements styling for RTL. Might this work for you?
[dir="rtl"] {
&selector {
// RTL specific
}
&selectorN {
// RTL specific
}
}
Use below scss to get expected output
#app {
width: 300px;
height: 300px;
background: red;
&[dir="ltr"] h1{
margin-left: 10px;
}
&[dir="rtl"] h1 {
margin-right: 10px;
}
}
Probably you are going a little in the wrong direction.
Most of the time, you can achieve this automatically, no need for specific selectors.
Margin, for instance:
Just set it both for left and right margin. The browser will choose the correct one for you
#app {
width: 300px;
background: tomato;
margin: 10px;
}
h1 {
margin-left: 15px;
margin-right: 5px;
}
<div id="app" dir="ltr">
<h1>
margin left 15
</h1>
</div><div id="app" dir="rtl">
<h1>
margin right 5
</h1>
</div>
I understand CSS basics, but I keep running into trouble with conflicting styles. Consider the following styles.
First, the default font color in my style sheets is black. I want that color applied to all picture captions - unless they're contained in divs with a class CoolL or CoolR...
.CoolL .Caption, .CoolR .Caption { color: #900; }
Now all the captions in the Cool series have brown text. But there are situations where I want the captions to have a black background with white text, so I created this rule:
.Black { background: #000; color: #fff; }
Now consider the following HTML. Class Caption by itself should have black text. However, this is inside a div with a class CoolR, so it displays brown text instead. But I added the class Black to the last div, which should change the background to black and the text color to white...
<div class="CoolR Plus Max300">
<div class="Shadow2">
<img src="">
<div class="Caption Black">Text</div>
</div>
</div>
In fact, the background is displaying black, but the text color is still brown.
I get these problems all the time, and the only way I can fix them is to write long, detailed styles, like this...
.Black, .Caption .Black, .CoolR .Caption.Black, .EverythingElseThatCouldBeBlack .Black { background: #000; color: #fff; }
What am I missing? Thanks.
I think you are over complicating things. This will become a maintenance issue as you add more styles. I would define separate classes and keep things simple. It's also important to understand CSS specificity.
.caption {
color: #000;
}
.cool-caption {
color: #900;
}
.caption-with-background {
background-color: #000;
color: #fff;
}
You could try :
.Black { background: #000 !important; color: #fff !important; }
There are a few fixes, but as previously recommended you should mark all of the settings you want to override previous ones with !important. With that, your code would look like this:
.Black {
background: #000;
color: #fff;
}
Also, not sure if you asked this, but you can apply CSS to all components by using the *, like so:
* {
//blahblahblah
}
you are defining the first case with a descendant selector which overrides the second class, which is merely a class. every answer given already will work but are entirely unnecessary. just add this to your style sheet:
.CoolR1 .Black, .Black{ background: #000; color: #fff;}
/** you could also chain your classes for specificity power **/
.Black.Caption{color:#fff}
that should do it. you can read more about selectors here:
http://docs.webplatform.org/wiki/css/selectors
I think that generally a more specific rule overrides a more general one, thus the more specific '.CoolR .Caption' is overriding the more general .Black. You'll probably be able to override this with !important, but a better style might be to reduce the complexity of your rules:
.Cool .caption { color: #900; }
.Cool .caption.black { color: background: #000; color: #fff; }
And put .L and .R in separate classes
.Cool.L { . . . } /* For things specific to CoolL, but not CoolR */
.Cool.R { . . . } /* and vice-versa */
If I would like to format an element that has a given class, sometimes (very rare) I use:
.beigeButton[class~="enabledButton"] {
}
What if I want to give properties to an element only when it does NOT contain the given string?
This does not work:
.beigeButton[class!="enabledButton"] {
}
How can I do that?
Use :not:
.beigeButton:not(.enabledButton)
In general you would style the basic button and overwrite the style with additional classes, somehow like this:
.beigeButton {
background-color: beige;
cursor: pointer;
}
.beigeButton.disabled {
background-color: grey;
cursor: not-allowed;
}
.beigeButton.enabled {
background-color: green; //or just keep the basic color
}
you could also define a more general 'disabled class' which can be applied to any other Element this way:
.disabled {
background-color: red;
pointer: not-allowed;
}
A button with the class 'disabled' will get a grey background, though the rule .beigeButton.disabled is more specific as the general .disabled rule.
Any other element (or if the more specific rule doesn't exist or apply) will get a red background-color.
edit:
To answer your initial question, you can style the other way round too, like marcinjuraszek already described:
.beigeButton:not(.enabled) {
background-color: grey;
cursor: not-allowed;
}
Note: check browser compatibilty here
Hope this helps :)
I have following html:
<div class="red placeholder"></div>
<div class="blue placeholder"></div>
<div class="green placeholder"></div>
and CSS:
.placeholder {
width: 100px;
height: 100px;
margin: 10px;
border: 1px solid black;
}
.placeholder:hover {
background-color: gray;
}
.red {
background-color: red;
}
.blue {
background-color: blue;
}
.green {
background-color: green;
}
I should not change initial placeholder declaration(s) and I don't want DIVs to change colour on hover.
Is there any way I can override placeholder class to "cancel" or turn off that hover property?
jsFiddle: http://jsfiddle.net/8QJEq/4/
That was really a good question, since am not able to work out any easier way than this, you can check out my solution
div[class="red placeholder"]:hover {
background-color: red;
}
div[class="blue placeholder"]:hover {
background-color: blue;
}
div[class="green placeholder"]:hover {
background-color: green;
}
Demo
Explanation: What we are doing here is, we are selecting the elements having a combination of 2 classes, and than we use the same color on hover, which is their default background-color, so inshort, this won't take out the hover, it does hover, but because of the same background color, you won't see any change.
I would recommend to avoid targeting the elements in the first place if at all possible.
If that's not possible, you could just declare the hover state with each color. As long as .color:hover is declared after .placeholder:hover it will override it since they share the same specificity.
jsfiddle 1
CSS
.color, .color:hover { background-color: color; }
Though I wouldn't recommend it, but it sounds like you don't want divs with color classes to not change background-color you could also just declare the rules as !important. But this would only be a last resort option since you wouldn't be able to easily override the background-color again.
jsfiddle 2
CSS
.color { background-color: color !important; }
So I am providing the resources for my celllist via the constructor. Everything seems to work, I have provided my own style sheet:
.cellListWidget {
color: #021650;
background-color: #021650;
}
.cellListEvenItem {
cursor: pointer;
zoom: 1;
background: red;
}
.cellListOddItem {
cursor: pointer;
zoom: 1;
background: blue;
}
.cellListKeyboardSelectedItem {
background: #ffc;
}
.cellListSelectedItem {
background-color: green;
color: white;
height: auto;
overflow: visible;
}
I must not understand it quite right because the background color I tried to set for the widget does not seem to take any effect. The rest of the styles work though, even item, odd item, selected item, etc.
Just to clarify, I want to change the color of the whole column this list is on, it items in the list are obviously styled, but the list takes up more vertical space than there are items, so where there are no items, is just a grey color which I want to change.
The solution I found was to not style the cell list, but the flowpanel that the cell list was on.
