HTML-CSS : Exercise-6 with Solution

Using HTML, CSS create a custom hover and focus effect for navigation items, using CSS transformations.

Use the :before pseudo-element at the list item anchor to create a hover effect. Hide it using transform: scale(0).
Use the :hover and :focus pseudo-class selectors to transition the pseudo-element to transform: scale(1) and show its colored background.
Prevent the pseudo-element from covering the anchor element by using z-index.

HTML Code:

  list-style: none;

.hover-div li {
  float: left;
}

.hover-div li a {
  position: relative;
  display: block;
  color: #fff;
  text-align: center;

  background-color: #F68026;
  z-index: -1;
  transform: scale(0);
  transition: transform 0.5s ease-in-out;

HTML-CSS: Tips of the Day

What is the difference between id and class in CSS, and when should I use them?

Example:

#header_id {font-color:#fff} .header_class {font-color:#000}

(Note that CSS uses the prefix # for IDs and . for Classes.)

However color was an HTML 4.01 <font> tag attribute deprecated in HTML 5. In CSS there is no "font-color", the style is color so the above should read:

Example:

#header_id {color:#fff} .header_class {color:#000}

The text would be white.
