HTML-CSS : Exercise-7 with Solution

Using HTML, CSS create a scrollable container that will snap on elements when scrolling.

Use display: grid and grid-auto-flow: row to create a vertical layout.
Use scroll-snap-type: y mandatory and overscroll-behavior-y: contain to create a snap effect on vertical scroll.
You can use scroll-snap-align with either start, stop or center to change the snap alignment.

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.
