Can I add a mixin to a variable in LESS?
Something like this
#input-border-radius: .rounded();
or
#h1: .font-size(46) // This pulls from the rem calculator mixin.
Looked at the LESS Docs but can't see a way to do it.
There is a way.
You can define properties of a (possibly immaginary) class and recall the properties of that class in the style of a different class. For example:
.fontstyling {
font-weight: bold;
color: black;
}
h1 {
font-size: 46px;
.fontstyling;
}
h2 {
font-size: 38px;
.fontstyling;
}
(thats not the best way to format the headings - but for other exemples it is really useful!)

I am making a theme editor for WordPress, and would like to use less to build the CSS file.
I have put a string in a variable like this:
#banner-separation-style: 'thick_border';
Then I'm trying to use when() like this:
when (#banner-separation-style = 'thick_border') {
header {
... some style
}
... and some css selectors
}
I've also tried combinations without quoting the variable.
How do I properly create something similar to if-blocks with less?
Guards (when statement) can only be used along with a mixin or a CSS selector. We can't write a when statement without using one of those. So, either write it with a mixin like below:
#banner-separation-style: 'thick_border';
.border-styles() when (#banner-separation-style = 'thick_border') {
header { border: 2px solid red; }
nav { border: 2px solid green; }
}
.border-styles;
or directly with the CSS selector like below:
#banner-separation-style: 'thick_border';
header when (#banner-separation-style = 'thick_border') {
border: 2px solid red;
}
nav when (#banner-separation-style = 'thick_border') {
border: 2px solid green;
}
or atleast using an unnamed selector (&) like below:
#banner-separation-style: 'thick_border';
& when (#banner-separation-style = 'thick_border') {
header { border: 2px solid red; }
nav { border: 2px solid green; }
}
The first version (with mixin) is the one that I prefer because (a) you don't have to repeat the condition multiple times like in the CSS selector version and (b) giving the mixin a name makes it more readable than using an unnamed selector. It is just my choice and some other user could actually prefer the last because it doesn't need that extra mixin call statement.
Is it possible in Less to setup mixin informations that can read phpStorm?
I write a Mixin like this:
.action-btn(#size: 32px, #color: #fff, #bgColor: #overlayStyleBlack, #bgColorHover: #red) {
a {
width: #size;
display: block;
color: #color;
text-align: center;
line-height: #size;
background-color: #bgColor;
&:hover {
cursor: pointer;
background-color: #bgColorHover;
}
}
}
What i want now is, that when i use this mixin in another less file: ".action-btn();" then i want to see that i have in this Mixin 4 Settings that i can Setup. In php Classes i can do this with:
/**
* #param string $xxx
* function to check and change user is_online flag in sphinx and in mysql
*/
But this dont work in the Less Mixin File.
And how can i Skip some settings? Here a example to explain what i mean. (This ry dont worked)
.action-btn(64px, , , #fff);
Is there a way to use property names as variables in LESS?
For example:
h1 {
font-size: 16px;
line-height: font-size * 2;
}
The above snippet doesn't work, and I wonder how to get this effect?
I don't think it's possible.
A workaround is creating a variable and assign the font-size to it. Then you can use this to multiply the value:
#fontsize: 16px;
h1 {
font-size: #fontsize;
line-height: #fontsize * 2;
}
I have a common.less file, that implements the basic CSS for different skins:
#textColor: black;
#iconSize: 16px;
.container: {
color: #textColor;
background-color: white;
}
.icon: {
width: #iconSize;
height: #iconSize;
}
// note that #iconSize is also used in this file inside mixins
The plan is to use it like so skin_1.less:
#iconSize: 32px; // override the icon size
// but leave #textColor as default
#import "common.less";
.container: {
color: red;
}
// I would now have big icons and red text
So I would like to have a common style, that I can reuse and selectively override variables.
This does not ssem to work however. I think it's because imports are always moved to the top, so variables cannot be pre-defined.
(I also read that variables are rather constants, so that may be another problem.)
Anyway: is there a better pattern to solve my use case?
You don't need to split the files up, just override the variable after the import. Variables are always resolved as the last definition, even if it is after where it is used.
I'm using the LESS CSS module 7.x-2.4 in Drupal 7.8
I would like to use style mixins which pass arguments to another mixin. In the example passing the color as a string "#CC00CC" works ok, but not as an variable like that "darken(#col, 10%)".
#bg(#colBg){
background-color: #colBg;
}
#style(#col){
border: 2px solid lighten(#col, 10%); // ok
#bg(#CC00CC); // ok - color is passed
#bg(darken(#col, 10%)); // Color is not being passed to #bg
}
.buttonSubmit{
#style(#FF00FF);
}
How can I achieve cascading variables from the css-class to a mixnin which passes the argument to another mixin?
Your syntax is incorrect. Check the docs on mixins. The code you have should be written like this:
.bg(#colBg){
background-color: #colBg;
}
.style(#col){
border: 2px solid lighten(#col, 10%);
.bg(#CC00CC);
.bg(darken(#col, 10%));
}
.buttonSubmit{
.style(#FF00FF);
}
