Accent Colors & Highlighting

Part of the Practical Frontend section of Coddy's HTML journey — lesson 14 of 35.

Accent colors help important elements stand out, such as buttons, links, call-to-action sections, or highlighted text. You can define them as CSS variables (--primary-color, --accent-color, --highlight-color) and use them consistently throughout your site. Hover states and highlights can also use these variables, making it easy to create a visually appealing and cohesive theme while drawing attention to key content.

Create a CSS variable for your accent color:

:root {
  --accent-color: #ff6b6b;
}

Use the accent color for important interactive elements like buttons:

.button-primary {
  background-color: var(--accent-color);
  color: white;
}

Highlight active navigation items using the accent color:

.nav-item.active {
  color: var(--accent-color);
  border-bottom: 2px solid var(--accent-color);
}

Challenge

Easy

Your task:

Set the accent color using a CSS variable --accent-color.
Apply the accent color to all buttons on the page.
Change the hover state of the buttons to primary color.
Apply the accent color to links, highlighted text, and footer links for consistency.
