Static image path in sass - less

In less you could always do this. You make a variable for the image path, and than you can insert the image path in the background url. How can I make this in SASS?
#static-path: "../../static";
background: url("#{static-path}/img/bg-header.jpg") repeat-x left bottom;

In SASS we define variables with $.
So define variable called path $img_path: "../../static";.
Then use something called interpolation (sass docs):
background: url("#{static-path}/img/bg-header.jpg") repeat-x left bottom;
When you are using COMPASS in your project you may use image-url() instead of url(), which grabs your image path from COMPASS config file.

Conditionally set main color in Vue

I wrote a reusable app in Vue and I compiled it as a library. I set the global variable $brand-color in SCSS file which is a main color of the app (buttons, borders, font colors). I use this variable in other SCSS component files.
I've put my app to my client's website and everything is working fine. Right now I have another client who is willing to use my app. BUT... new client wants to have my app in different $brand-color than my old one. What would be the best way to approach this problem?
One thing which comes to my mind is to set store variable with value of $brand-color which depends on location.host and bind styles of all "branded" elements.
switch (location.host) {
case 'client1.com':
context.commit('setMainColor', '#ff0000');
...
case 'client2.com':
context.commit('setMainColor', '#16c100');
...
}
But this will be very painful. I would need to apply a lot of changes in all my components. Is there any better solution that style-binding all components?
By the way, I can't use CSS variables because code needs to be IE friendly.
You can have 2 files, each file definne scss variable for different customer:
customer1_variables.scss
$brand-color: green
customer2_variables.scss
$brand-color: red
And you can import it in javascript file
main.js
switch (location.host) {
case 'client1.com':
import './customer1_variables.scss'
...
case 'client2.com':
import './customer2_variables.scss'
...
}
Another solution is using vue-style-component. You can check this article for more detail
So finally I set store value depending on my client and prepared set of SCSS classess specified for each client, i.e.:
.btn-client1 {
background: red;
}
.btn-client2 {
background: blue;
}
...
and I binded classes for specific elements:
:class="`btn-${client}`"`

sass: overwrite one var with another

We've got our sass variables file set up like
scss\variables\_custom_variables.scss.
Which, of course contains things like
$link-color: $00f;
Then put to use in our sass files set up like this one for navigation as scss\main\_main_nav.scss where we have rules like
a {color: $link-color;}
Now we've got a new feature allowing for custom styling, which pulls in the variables as well as everything in scss\main\. In lieu of creating something like
scss\main_2\_main_nav.scss ad infinitum
I'd like to be able to redefine $link-color.
I was hoping I could simply create scss\new_file\_variables.scss and have a list of overrides like
$link-color: #36c;
but this is not working as expected. What could I be doing better?
Thanks, all
You can define your base-variables with the default-flag: $var1: lightblue !default;
and override them in the theme using $var1: red;
If you #import the variable-files in the right order, red overrides lightblue.

Complicated colour scheme definition in LESS / Joomla T3

I'm building a site in Joomla 3 on T3 framework.
I'm having to use LESS for the first time, but am experienced with CSS.
The site will have differently themed landing pages. These will all be identical except for the colour scheme.
I am attempting to set up a colour scheme in the T3 'variables' less file and then implement the colours - the colour will be different for many core components - such as H1, P, DIV Background Color, etc.
So if I set up, say, a master colour for Thailand's page, I create this rule in the variables.less file:
#thai: #e55092;
and then my knowledge of exactly how LESS compiles to CSS falls flat and I lose my entire train of thought.
Because I now want to be able to set up a landing page for Thailand in the T3 template. I need to be able to use the class 'thai' in various places in this page - for instance, the H1 text should be coloured #e55092, an aside background should be #e55092, an HR should be #e55092 ... for THIS page only.
I hope this isn't a too open question but what would be best practice for achieving this, keeping my code clean and fast? My current line of thought is that I create a whole bunch of rules in LESS along the lines of:
thai.h1 { color: #thai }
thai.button [ background-color: #thai }
(excuse syntax - very new to LESS and not sure what's possible or correct)
But isn't that defeating the whole purpose of using LESS in the first place?
I think your question is very broad indeed. Depending on your situation:
One CSS file for all pages. You can consider changing selector order The code for a button can then look like that shown beneath:
.button {
border: 1px solid white;
.thai & { background-color: red;}
.japanese & { background-color: yellow;}
}
In your HTML pages: <body class="thai"> and so on..
Compile different CSS files for each landing page
In Less you can override a variable by putting the definition afterwards
You should first define a main file, for the button example this button.less file should contain something like that shown below:
#button-background-color: orange;
button { background-color: #button-background-color; }
Now you can define you thai theme file (thai.less) as follows:
#import "button.less";
#button-background-color: red;
Or alternatively compile different CSS files using the modify-var option:
lessc button.less --modify-var="button-background-color=red" thai.css

getAttribute not returning complete value for style in selenium

I am using the selenium getAttribute("style") method on the following id element:-
<div id="ntsDiv_1" style="width: 250px; text-align: left; white-space: normal; top: 1090px; left: 131px; visibility: hidden;" class="mlt-pop-container">
but the API is returning only the half of the value. It is returning width: 250px; text-align: left; white-space: normal; and the remaning portion of the style is clipped.
I'm trying to extract the value of the visibility, but the method is not returning the complete value of style. Hence, i am unable to determine the correct value of visibility.
I executed System.out.println("Style is:- "+super.getElement(NEXTAG_STORES_DIV).getAttribute("style"));
NEXTAG_STORES_DIV corresponds to the xpath of the id element, and super.getElement extracts element by xpath
Please help me out!!
I just tried this with Selenium 2.30.0 and it works fine, the whole attribute is returned.
Try the following things (all the examples assume element is the WebElement you need to test):
Make really sure only a part of the attribute is returned. Aren't you just printing it into console? Many consoles have a limited line length. Try setting your console to show long lines. Check programatically the length of the returned value, or try evaluating
element.getAttribute("style").contains("visibility")
Try upgrading your Selenium library, if you can. I am not aware of any bug related to attribute getting, but there might have been some which is now (with version 2.30.0) solved.
Try it in a different browser / OS / architecture. If it works somewhere, you'll know it's an issue of a particular browser / driver / OS / architecture / whatever and you might be able to focus it down and either fix it or file a bug.
If you simply want to know whether an element is visible or not, the correct and generally preferred way is to call
element.isDisplayed()
This method takes care of all the rules you might need to inspect in order to determine whether it actually is visible or not.
If the style value changes dynamically on the page (i.e. it's not statically written in the source code of the page), WebDriver can't really see it as it doesn't pick up dynamic changes. Try accessing the value via JavaScript:
if (!driver instanceof JavascriptExecutor) {
throw new IllegalStateException("JavaScript not enabled for this driver!");
}
JavascriptExecutor js = (JavascriptExecutor)driver;
String styleAttribute = (String)js.executeScript("return arguments[0].style", element);
If you actually need to get the computed value of the CSS visibility attribute that is actually used by the browser and not the one in the style atribute (if there either isn't any or is somehow overridden), you need to use the JavaScript's getComputedStyle() method. One way (described by this article on quirksmode.org) is this:
var elem = arguments[0];
if (elem.currentStyle) {
var vis = elem.currentStyle['visibility'];
} else {
var vis = document.defaultView.getComputedStyle(elem, null).getPropertyValue('visibility');
}
return vis;
Again, this should be invoked via
String visibility = (String)js.executeScript(here_goes_the_whole_script, element);

Compass - Get width and height of generated sprite-map

I'm building a Sencha Touch mobile application and are using the functionality to create image-sprite-maps with Compass.
Is there any way to calculate the size of the image-map (width and height) and put it as a variable in your SCSS file?
In Compass, image-height and image-width are the functions to get image dimensions. Using them with your sprite map would look something like this (warning, untested):
// Assuming $my-sprites is your sprite map variable
$map-path: sprite-path($my-sprites);
$map-height: image-height($map-path);
$map-width: image-width($map-path);
In the latest version of Sass (3.4) sprite-path() returns the full filesystem path while image-width() expects a path relative to the images directory. But there is a simple solution:
sprite-width($sprite-map);
sprite-height($sprite-map);
You can get a unit value by using the magical dimension functions <map>-sprite-height and <map>-sprite-width.
// Note: "my-icons" represents the folder name that contains your sprites.
#import "my-icons/*.png";
$box-padding: 5px;
$height: my-icons-sprite-height(some_icon);
$width: my-icons-sprite-width(some_icon);
.somediv {
height:$height + $box-padding;
width:$width + $box-padding;
}
Check the official documentation for more details.
Ext.getBody().getSize() gets you height and width of the screen but i dont think you can write this in SASS
