Description
Variable scope specifies place of the available variable. The
variables will be searched from the local scope and if they are not
available, then compiler will search from the parent scope.
Example
The below example demonstrates use of namespaces and accessors in the LESS file:
<html>
<head>
<title>Less Scope</title>
<link rel="stylesheet" type="text/css" href="style.css" />
</head>
<body>
<h1>Example using Scope</h1>
<p class="myclass">LESS enables customizable, manageable and reusable style sheet for web site.</p>
</body>
</html>
Next, create file
style.less.
style.less
@var: @a;
@a: 15px;
.myclass {
font-size: @var;
@a:20px;
color: green;
}
You can compile the
style.less file to
style.css by using the following command:
lessc style.less style.css
Next execute the above command, it will create
style.css file automatically with the below code:
style.css
.myclass {
font-size: 20px;
color: green;
}
Output
Let's carry out the following steps to see how above code works:
- Save the above html code in scope.html file.
- Open this HTML file in a browser, an output as below gets displayed.
