I am fairly new Less and have been trying to get a jQuery plugin to work with my custom CSS generated via Less. Basically, what I have is the following html generated by a plugin:
<div class="classA class B" ....>
<div class="classC classD" ....>
<div class="classE classF" ....>
..........
I am not sure how to structure my Less file in order to generate CSS that matches the above.
I have tried:
.classA {
......
&.classB {
.....
&.classC {
....and so on
but it generates the following CSS:
.classA {...}
.classA.classB {....} /*This does not include the CSS of classA */
.classA.classB.classC {.....} /*This does not include CSS of classA or classB*/
...
The plain CSS is fairly easy to write :
.classA {.....}
.classB {.....}
and when I write
how do I achieve the above using Less? Is there a simple way to achieve this without using functions or extends?
Nesting elements in less has the result you're describing when adding the & : you specify the selector that uniquely matches with that parent and child class (.classA.classB in CSS ),
to do what you're asking
.classA {.....}
.classB {.....}
you simply shouldn't nest_
If your goal is to inherit styles of one class by another one, you can use mixins:
.foo() {
background: #ccc;
}
.bar {
.foo;
color: #000;
}
Output CSS:
.bar {
background: #ccc;
color: #000;
}

I have these elements on the HTML:
<div id="td-status" class="icongb-cancelled"></div>
<div class="ticket-header-text">
<span class="bet-text">TEXT1</span>
<span>TEXT2</span>
</div>
and I want to apply a certain style using LESS to TEXT1 ('bet-text' class) whether its uncle has a cercaion class (in this case icongb-cancelled). I'd like to apply it also to TEXT2 (no class). Would it be possible?
I'm using this code, but it doesn't work:
.icongb_cancelled ~ .ticket-header-text {
& .bet-text {
color: #959595;
}
}
NOTE: I don't want to use JQuery to add or remove any class.
I want to make it just using LESS wihtout any modifying on the HTML.
Thanks in advance.
EDIT: The code was fine, the problem was that I was using an underscore instead of a dash. so you can use that code to apply a style to a nephew element.
You're using .icongb_canceled in the selector, but the class is icongb-canceled.
Dash vs underscore. They need to match.
You can write .icongb-cancelled ~ .ticket-header-text .bet-text, which is valid in CSS, but also is LESS compatible:
.icongb-cancelled ~ .ticket-header-text .bet-text {
color: blue;
}
.icongb-cancelled ~ .ticket-header-text span {
color: green;
}
<div id="td-status" class="icongb-cancelled"></div>
<div class="ticket-header-text">
<span class="bet-text">TEXT1</span>
<span>TEXT2</span>
</div>
To select all the links that have not yet been visited we can use a:link. Suppose we used a class based implementation to style links like this:
.Link {
...
}
And we then apply this to anchor elements to style them like this:
<a class="Link">..</a>
Would it make sense to also implement .Link:link {}, while also implementing .Link:visited {}, .Link:hover {}, .Link:active {}. In seems that in this context .Link:link {} and just plain .Link {} do the same thing?
I recently encountered a.. "thing" in the land of SASS. And maybe you guys know a trick or something alike to "fix" it.
I've got this class .icon. It contains some basic styling for my icons (Used for an iconfont). These icons can then be placed in the markup whereever I want. For example in a button. But inside the button this icon needs some extra styling. So I do the following:
.icon {
// Basic styling
}
button {
.icon {
// Additional styling
}
}
It compiles to this css:
.icon {
// Basic styling
}
button .icon {
// Additional styling
}
Everything OK so far. But now I want to extend the .icon to an after-element inside of all my .foo elements like so:
.foo:after {
#extend .icon;
}
Now it compiles to this css:
.icon, .foo:after { // This is good, exactly what I want
// Basic styling
}
button .icon, button .foo:after { // But I don't need the second half of this line
// Basic Additional
}
Now the foo-element isn't just extending the "root" icon-class but also the icon-class under button and all its additional stylings. But I don't need that. I don't want that element to have that additional styling. It doesn't result in problems yet. But maybe that could happen later. So I was curious if it is possible to extend only the .icon from the root, omitting the nested .icon in the button, and possibly more nested icon-classes in other elements later on.
My first thought was to use an abstact class like %icon and extend from that, but the above mentioned icon-class, and the file that it is placed in, is generated by grunt-webfont. So I can't just change the icon-class styling 'cause its overwritten all the time.
What can I do? Is there some more to the extend function of SASS that I don't know of? Or is there a totally different way?
Thanks for any help.
SOLUTION:
Using all the awesome help and tips I found a way to avoid this problem:
Grunt-Webfont suggests to use the i-tag to display the icons. Font-Awesome does the same. So, I'm doing exactly that. And I usually don't use it for anything else.
This allows it to use the i-tag under the button for my extra styling, and not the .icon class. This way the .icon class is used only once in the generated file and then never again.
.icon {
// Basic styling
}
button {
i { // <= Previously '.icon'
// Additional styling
}
}
Have you tried doing something like this?
.icon {
//some styles from external (ie: grunt webfont)
color: red;
}
%icon {
#extend .icon;
}
button {
.ico {
#extend %icon;
//add some additional styles
}
}
.foo:after {
#extend %icon;
//add some more
}
You would then avoid generating the foo:after rule for the .icon inside the button.
EDIT2 - you'll need to create an additional class which you can use inside your styles, so there's only one .icon class defined (in your grunt-webfont generated css). Then just use the .ico class inside your styles and extend the %icon placeholder like shown above.
EDIT - have you considered solving this problem in your grunt-webfont generator?
From the documentation, it seems you can set the output to scss like so:
options: {
stylesheet: 'scss',
mixinPrefix: 'mixin-'
Then just use the mixin to define the styles of your desired classes?
I think this gets the result you're looking for? Albeit, slightly messily.
The method: make a placeholder style and extend that into .icon to begin with.
%icon-styles{
basic: styling;
}
.icon {
#extend %icon-styles;
}
.foo:after {
#extend %icon-styles;
}
button .icon {
#extend %icon-styles;
additional: styling;
}
It compiles into:
.icon, .foo:after, button .icon {
basic: styling;
}
button .icon {
additional: styling;
}
You can also use custom template with grunt-webfont. It’ll give you much more control on generated CSS.
I've got a jquery slider function on a page, and when the slide rotates I need the style of a LI tag to change.
So when the slider goes onto a li the class looks like this:
<li class="first sliderkit-selected">
And when it moves off it looks like this:
<li class="first">
But when the class goes to "first sliderkit-selected" I need it to be referenced from the style sheet but not sure how it is constructed, so far I've played around with:
li.sliderkit-selected li.first {
background-color: red;
}
But it doesn't seem to pick it up.
I know you could use a comma inbetween each class, but I want a style to be referenced exclusively when those two class's are together, if that makes any sense.
Thanks.
You're looking for li.sliderit-selected.first:
li.sliderkit-selected.first{
background-color: red;
}

CSS Selectors Level 3: Class selectors
The following rule matches any P element whose class attribute has been assigned a list of whitespace-separated values that includes both pastoral and marine:
p.pastoral.marine { color: green }
This rule matches when class="pastoral blue aqua marine" but does not match for class="pastoral blue".
To select a DOM element with multiple classes, concatenate the classes in the selector:
li.sliderkit-selected.first {
background-color: red;
}
If you want to select an element with multiple classes, you simply append the classes with a dot, like this:
li.first.sliderkit-selected { /* your rules */ }
This means "a li tag with the class first and the class sliderkit-selected".
You can write like this:
.sliderkit-selected.first {
background-color: red;
}
OR
.first.sliderkit-selected {
background-color: red;
}
This is probably a case of trying to run before I can walk, however... I have the following code:
<div class="hidden" id="repair_complete">
// some code
</div>
I was under the impression that if my CSS file contained:
#hidden {
display: none;
}
... then the div content wouldn't display. However, it seems to only adopt this behaviour if the CSS file contains a reference to the div id:
#repair_complete {
display: none;
}
In a book I'm working through the opposite seems to be true - the style sheet refers to the class name, not the id.
Any ideas where I'm going wrong?!
Your CSS syntax is incorrect.
If you want to access this div, you can do it like this:
/* By class: */
.hidden {
display: none;
}
/* By ID: */
#repair_complete {
display: none;
}
Note that to access an element by class you use a dot before the class name. You use a hash before the ID.
The other answers have the technical stuff right: you need .hidden, not #hidden.
Now you have to decide whether you want to attach CSS to divs by class or id. I find classes are better in the long run, unless you are really certain that there will ever really and truly be one of the thing you are making.
Also, don't forget that you can attach more than one class to an element:
<div class="red fat shallow">blah blah</div>
Then you can style this element with any of these selectors:
.red {...}
.fat {...}
.shallow {...}
.red.fat {...} /* Applies only to things that are both red and fat */
.red.fat.shallow {...} /* Very specific */
/* etc. */
A "." before the name will refer to classes, and a "#" will refer to ids:
.hidden
{
display: none;
}
You need:
.hidden{
display:none;
}
period is a class specifier, pound sign is for id's.
To use class name use the dot.
i.e.
.hidden refers to the class name
#repair_complete refers to the id.
To refer to an element's ID you use the # selector, to refer to it's class name you use the . selector.
So in your example you would use
#repair_complete {
display:none;
}
or
.hidden {
display:none;
}
