referencing multiple mixins not picking the correct property values - variables

I have the following 2 mixins with different names in the same scope and defining the same variables - #width and #height:
.myMixin1 {
#width: 100%;
#height: 400px;
}
.myMixin2 {
#width: 75%;
#height: 200px;
}
I reference both the above mixins from within the same style rule:
.myClass {
.myMixin1;
.myMixin2;
width: #width;
height: #height;
}
This compiles to:
.myClass {
width: 100%;
height: 400px;
}
instead of
.myClass {
width: 75%;
height: 200px;
}
My question is:
Since .myMixin2 is referenced last, shouldn't the class pick up the property values from this mixin?

I figured this out:
Variables are not copied if the caller of the mixins contains variables with the same name defined by another mixin call. LESS Docs
After .myMixin1 is called, the caller already contains the variables #width and #height. Hence, a reference to .myMixin2 does not copy over the variables with the same name.

passing from specific class to props function sccs and vuejs

I want to pass a class according to a props without having to duplicate the scss code
indeed if I duplicate the code by putting the class it works but I would only like to modify certain value by adding the appropriate class
components
``` :class="[
theme === 'darkModeTheme'
? 'darkModeTheme'
: theme === 'toggleLanguage'
? 'toggleLanguage'
: ''
]"
// props
theme: { type: String }
```
here is an example of the scss
```
&:checked {
background: color(menu);
background-repeat: no-repeat;
background-size: 80px 40px;
.darkModeTheme { //class to be taken into account if defined on the component to call
background: url("../../../assets/img/sky-stars.jpg");
}
&::before {
.toggleLanguage {
background-image: url("~#/assets/img/en.png");
}
// background-image: url("~#/assets/img/en.png");
left: 40px;
}
}
&:before {
content: "";
position: absolute;
width: 30px;
height: 30px;
border-radius: 50%;
left: 0;
background-size: 30px;
background-repeat: no-repeat;
box-shadow: 0 2px 5px rgba(0, 0, 0, 0.8);
#include easeOut;
cursor: pointer;
// background-image: url("~#/assets/img/fr.svg");
.darkModeTheme { //class to be taken into account if defined on the component to call
background-image: color(toggleTheme);
}
.toggleLanguage { //class to be taken into account if defined on the component to call
background-image: url("~#/assets/img/fr.svg");
}
}```
In your template, the dynamic class should be defined like
:class="{
'darkModeTheme': theme === 'darkModeTheme',
'toggleLanguage': theme === 'toggleLanguage'
}"

Changing size of Dojo Filtering Select via CSS in XPages

I just want to change the size of Dojo Filtering Select design element via CSS.
I tried manual or CSS File. It did not work.
<xe:djFilteringSelect id="djselect1" value="#{document1.Language}" style="min-height: 8px;height:8.px;"></xe:djFilteringSelect>
Any suggestion is important

You just need to override the dijitTextBox CSS class.
You might need to use CSS specificity to make sure that the CSS is picked up (instead of using !important).
Here's a simple example:
.dijitTextBox {
width: 40px;
height: 8px;
}
As you are using Bootstrap theme you need to adjust the arrow button too.
This works for me:
.dbootstrap .dijitTextBox {
height: 24px;
}
.dbootstrap .dijitComboBox .dijitButtonNode.dijitArrowButton {
height: 22px;
}
.xsp.dbootstrap .dijitInputContainer {
padding-top: 0px;
}
.dbootstrap .dijitComboBox input.dijitArrowButtonInner {
margin-top: -3px;
margin-left: -5px;
}
.dbootstrap .dijitMenuItem {
padding: 0px 10px;
}

Using Less, can I not output a base class for extend?

Using Less, I can not output a mixin class by putting parens after the class name
.my-mixin()
{
color: red;
}
That way it must be used as a mixin and a developer can't accidentally use it as a class like <div class="my-mixin">something</div>.
If I do something similar with extend instead:
.my-base
{
color: red;
}
.my-class:extend(.my-base)
{
background-color: grey;
}
The generated CSS is:
.my-base, .my-class
{
color: red;
}
.my-class
{
background-color: grey;
}
How can I change my Less so that the .my-base class isn't output so that it can't be accidentally used?

Using rulesets in LESS for media queries

When using Sass I would do something global like this (which I got from CSS-tricks btw)
// Variables for MQ's
$mq-mobile-portrait : 320px !default;
$mq-mobile-landscape : 480px !default;
$mq-tablet-portrait : 768px !default;
$mq-tablet-landscape : 1024px !default;
$mq-desktop : 1382px !default;
Then I would create mixins for the media queries like this (I'll only include a few to give you an idea
// Mixins
// Both portrait and landscape
#mixin mobile-only {
#media (max-width : $mq-mobile-landscape) {
#content;
}
}
// Everything up to and including the portrait width of the phone
// Since it's the smallest query it doesn't need a min
#mixin mobile-portrait-only {
#media (max-width : $mq-mobile-portrait) {
#content;
}
}
So Sass has this #content which is great because it means that I don't have to declare the content within the mixin but can do an #include mixinName and it creates the parent wrapper for any CSS properties I need to put into it across different files. I discovered that this worked well for my work flow.
So here's an example of that in a partial .scss file:
section.footer {
height: 90px;
padding: 0 10px;
#include mobile-portrait-only {
padding-top: 10px;
background: $gum;
div.ftrLogo {
display: inline-block;
margin: 0;
height: 70px;
width: 45%;
div.smlLogo {
display: block;
background: url('../images/svg/small-logo2.svg');
width: 106px;
height: 49px;
margin: 0 auto;
padding: 0;
}
p.footer {
font-size: .375em;
color: $white;
text-align: center;
}
}
}
So as you can probably gather the #content allows you to just call an empty media query wrapper anywhere in your files (obviously you have to import all of your partials into one main file) but this is great.
Today I'm using LESS on a project and I like it a lot the problem is I can't seem to find an equivalent solution in LESS-land.
I was reading up on passing rulesets http://lesscss.org/features/#detached-rulesets-feature which looks like it's close to what I want but my brain is not understanding it today; I'm optimistic about tomorrow.
If anyone has tried anything like this or can immediately see the error in my ways; please provide your two cents. I really want to figure it out and thought to ask this gifted community of SO'ers.
Thank you in advance you're a baller!
// Variables for MQ's
#mq-mobile-portrait: 320px;
// Mixins
.mobile-portrait-only(#rules) {
#media (min-width: #mq-mobile-portrait) {
#rules();
}
}
Now you can use the following code:
div {
color: white;
.mobile-portrait-only({
color: white;
width: 100%;
max-width: 500px;
});
}
The above will compile into CSS code as follows:
div {
color: white;
}
#media (min-width: 320px) {
div {
color: white;
width: 100%;
max-width: 500px;
}
}
So detached rules are rules between {} assigned to a variable:
#detached: {};
Detached rules can be used as an argument for a mixin:
.mixin(#detached){}
You as call the above mixin with a detached rule as a parameter:
.mixin({color: red;});
or
#detached: {color: red;} // watch out for the last declaration wins rule for variables
.mixin(#detached);
Inside the mixin you should call the detached rules set to copy its properties and selectors (in fact you don't copy but insert them read for processing):
.mixin(#detached-rules) {
#detached-rules(); // parenthesis are required here
}
Finally for your example your code should look like that shown below:
#gum: url();
#white: white;
// Variables for MQ's
#mq-mobile-portrait: 320px;
// Mixins
.mobile-portrait-only(#rules) {
#media (min-width: #mq-mobile-portrait) {
#rules();
}
}
section.footer {
height: 90px;
padding: 0 10px;
.mobile-portrait-only( {
padding-top: 10px;
background: #gum;
div.ftrLogo {
display: inline-block;
margin: 0;
height: 70px;
width: 45%;
div.smlLogo {
display: block;
background: url('../images/svg/small-logo2.svg');
width: 106px;
height: 49px;
margin: 0 auto;
padding: 0;
}
p.footer {
font-size: .375em;
color: #white;
text-align: center;
}
}
});
}
I hadn't thought of doing it like Bass Jobsen suggested (although I've now seen that his approach is basically how the less docs do it), but I invented a mixin which I think is a bit more flexible. Though they are similar in result, I think the following solution allows for more customization and is easier to implement on the fly.
First I define the different sizes I want to use - to keep it simple, I'll just do two using a 'mobile first approach' (meaning if I don't include a media query, the rules will apply to all sizes and I should only include queries for sizes larger than mobile).
#tablet:~"(min-width:768px)";
#desktop:~"(min-width:1100px)";
Then the mixin:
.respond(#_size;#_rules){
#media #_size {
#_rules();
}
}
And Used Like the following:
.selector {
background:green;
.respond(#tablet,{
color:red;
background:blue;
});
}
And That Outputs:
.selector {
background:green;
}
#media (min-width:768px){
.selector{
color:red;
background:blue
}
}
With only two sizes to remember, it is easy enough just to do it the way Bass Jobsen suggested, but in practice, depending on how fine-grained I want my control to be, I may define up to 8 different media sizes (though I rarely use them all), and my approach above makes the process like calling one function rather than defining 8 different functions ( as I would do were I using the alternate approach ).
Hope this helps someone. It saves me a ton of time.

Can I override global variables from the calling scope

I need to override some global variables used within a mixin. However I'm reluctant to just change the variables in global space (wouldn't be overriding then)
Consider this given mixin with the required variable defined.
// Mixin and adjust the regular image class
.thumbnail {
display: block;
padding: #thumbnail-padding;
margin-bottom: #line-height-computed;
line-height: #line-height-base;
background-color: #thumbnail-bg;
border: 1px solid #thumbnail-border;
border-radius: #thumbnail-border-radius;
.transition(all .2s ease-in-out);
> img,
a > img {
.img-responsive();
margin-left: auto;
margin-right: auto;
}
// Add a hover state for linked versions only
a&:hover,
a&:focus,
a&.active {
border-color: #link-color;
}
// Image captions
.caption {
padding: #thumbnail-caption-padding;
color: #thumbnail-caption-color;
}
}
Yep, from Bootstrap... Now I want that mixin to work with different variables, without changing the global scoped ones. Can this be done?
article.publications {
.news-thumb {
#thumbnail-padding: 10px;
#line-height-computed: 20px;
#line-height-base: 30px;
#thumbnail-bg : black;
.thumbnail();
}
}
