How to use colors in editing

Or if you use Bootstrap, use one of the built-in contextual classes on your paragraph or heading tag.

<h2 class="text-danger">This heading is red</h2>

Bootstrap contextual classes:

• primary
• secondary
• danger
• success
• warning
• info
• light
• dark

Contextual colors come from your Bootstrap Theme (SASS, mixins & variables).

Font colors are set using CSS.

In your external style sheet, create a new class...

.redtext {

color:red;
}

Then, in your Code or Design View, highlight the text and hit Ctrl/Cmnd + T to wrap the text in a set of span tags...

<span>the text you want to turn red</span>

You then apply the redtext class to the span tag...

<span class="redtext">the text you want to turn red</span>
