I want to do a text mixin, but idk how to pass optional properties to the font-family.
In this example, it takes two values (if the first one is not supported by the browser it will use the second one)
This wont work: $fontFamily: "Montserrat SemiBold" | sans-serif
#mixin text($fontSize: 20px, $fontFamily: "Montserrat SemiBold" | sans-serif, ...) {
font-size: 16px;
font-family: "Montserrat SemiBold", sans-serif;
...
}
You can use parentheses:
#mixin text(
$fontSize: 20px,
$fontFamily: ('Montserrat SemiBold', sans-serif)
) {
font-size: $fontSize;
font-family: $fontFamily;
}

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;
}
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 new to bootstrap, and I added bootstrap 3 into my project and it shrunk all the font sizes, I never had any font size specified in these classes. I thought bootstrap 3 had the default size to 14.. is there something else I need to do?
Thanks
It appears to be happening, at least as of version 3.3.6, due to this block on line 1097:
html {
font-size: 10px;
-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
}
You can restore your font-size by adding this to your stylesheet:
html
{
font-size: 100%;
}
You can customize/override anything - if, for example, you load YOUR css file AFTER the bootstrap file, then your settings will override it. Whatever you can dream:
p {
font-size 18px;
}
and so on...
I strongly recommend digging into the source code: https://github.com/twbs/bootstrap/blob/master/dist/css/bootstrap.css
html {
font-size: 62.5%;
-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
}
body {
font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
font-size: 14px;
line-height: 1.428571429;
color: #333333;
background-color: #ffffff;
}
UPDATE: TO clarify, "No" you shouldn't have to do anything else. It sounds like there is another problem. The linked source code has changed since the original answer date... as of Feb 2015, it looks like this:
html {
font-size: 10px;
}
body {
font-size: 14px;
}
Assuming we've set our project up correctly, (bower install bootstrap is pretty easy)... attempting to echo text outside of the body should result in 10px text, inside body should be 14px.
If you don't see 14 point text inside the body, then something else might be stepping on it. I'd next inspect in in Chrome (for example) to confirm where the font-size was coming from.
I'd like to add that I think it's helpful to understand how these values we see in this /dist/css file are derived from less variables... the defaults should work out of the box, but you have easy control over everything, including the body text size: see http://getbootstrap.com/css/#less-variables.
