How to use font-awesome: A step-by-step tutorial

Here are some ways you can manipulate them, including changing their size and colour, rotating and flipping them, and stacking them:

Changing the size: You can change the size of them by using the fa-xs, fa-sm, fa-lg, fa-2x, fa-3x, fa-4x, fa-5x, fa-6x, fa-7x, fa-8x, fa-9x, or fa-10x classes. It provides classes to adjust the size of them relative to their container. These classes can make them larger or smaller based on your needs. For example, if you want to make an icon twice as large as its default size, you would use the class “fa-2x”. Here’s how to do it:

<i class=”fas fa-camera fa-2x”></i>

Editing and pasting them

Modifying an icon can be done using the class names associated with each icon. To use an icon, you simply need to find the appropriate class name from the library, and then include it in your HTML. Here’s an example:

<i class=”fas fa-paste”></i> 

Icon names and icon library

Every icon has a unique name, and these names are used as class names to represent the symbol in your HTML. The entirety of these icons and their associated names make up the library. For example, the class name for a camera icon is “fa-camera”, and it is part of the larger Font Awesome icon library.

Icon fonts and free icons

Font Awesome is essentially an icon font, which means it’s a font that displays symbols instead of traditional letters or numbers. It includes both free and paid. Free icons can be used in any project without any cost, and are typically more than sufficient for most use cases.

CSS class and navigation

A CSS class is used to specify which icon you want to display, and sometimes to specify additional styling. For example, the class “fas fa-camera” is used to display a solid camera icon. When it comes to navigation, symbols can provide a visual cue to users. For example, an icon of a house might represent the home page.

Sizing and font-size

In addition to the specific sizing classes like “fa-2x”, “fa-3x”, etc., you can also adjust the size of them using the standard CSS “font-size” property. This is because Font Awesome behaves similarly to text. For example, to make an icon twice as large using “font-size”, you might do:

i.fas { font-size: 2em; } 

This would make all Font Awesome solid icons twice as large as the base font size.

Changing the colour: You can change the colour of them by using CSS. To do this, you need to target the icon element in your CSS code and use the color property to specify the desired colour. For example, to make an icon red, you would use the following code:

.my-icon { 
 color: red;
}

<i class=”fas fa-camera my-icon”></i>

Rotating and flipping icons: You can rotate and flip them by using the fa-rotate-* and fa-flip-* classes. These classes allow you to rotate icons by 90, 180, or 270 degrees, or flip them horizontally or vertically. For example, to rotate an icon by 180 degrees, you would use the following code:

<i class=”fas fa-camera fa-rotate-180″></i>

Stacking icons: You can stack multiple icons on top of each other by using the fa-stack class and nested fa-stack-1x and fa-stack-2x classes. This allows you to create more complex icon designs by combining multiple icons. For example, to stack a camera icon on top of a circle, you would use the following code:

<span class=”fa-stack fa-lg”>

  <i class=”fas fa-circle fa-stack-2x”></i>

  <i class=”fas fa-camera fa-stack-1x fa-inverse”></i>

</span>

In this example, we are using the fa-stack class to create a stack of icons, and then use the nested fa-stack-1x and fa-stack-2x classes to specify the size of each icon in the stack.
