HTML-CSS : Exercise-5 with Solution

Using HTML, CSS create a list with floating headings for each section.

Use overflow-y: auto to allow the list container to overflow vertically.
Use display: grid on the inner container (<dl>) to create a layout with two columns.
Set headings (<dt>) to grid-column: 1 and content (<dd>) to grid-column: 2.
Finally, apply position: sticky and top: 0.5rem to headings to create a floating effect.

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.
