Less.js is a simple CSS pre-processor that facilitates the creation of manageable, customizable, and reusable style sheets for websites. It is preferable since CSS is a dynamic style sheet language. Since LESS is flexible, it can be used with many different browsers. Web browsers can only use CSS that has been developed and processed using a computer language known as the CSS pre-processor. It is a CSS language extension that also offers features like variables, functions, mixins, and operations to aid in the creation of dynamic CSS while keeping backward compatibility.
In this article, we are going to discuss Misc image-width() Function, whose function is to determine the width of an image. This function returns the width in pixel value of the image whose name is passed into the image-size() function.
Syntax:
image-width("string")Parameters:
- string: This is the only compulsory parameter for this function. This parameter takes the string value of the name of the image.
Compile LESS code into CSS code.
Example 1: The code below demonstrates the usage and implementation of the Misc image-width() Function.
<!DOCTYPE html> <html>
<head>
<link rel="stylesheet" type="text/css" href="style.css" />
</head>
<body>
<h1 style="color:green;">

Syntax: To compile the above LESS code to CSS code, run the following command.
lessc style.less style.css
The CSS output of the above Less file was compiled into the following file.
style.css:
body { background-color: #eeeeee;
} .c1 {
width: image-width('1.png');

background-image: url("1.png");
background-repeat: no-repeat;
margin: 1rem;
margin-left: image-width('1.png');
} |
Output:
Example 2: The code below demonstrates the usage and implementation of the Misc image-width() Function and using the ispixel and boolean functions alongside it.
<!DOCTYPE html> <html>
<head>
<link rel="stylesheet" type="text/css" href="style.css" />
