HTML-CSS: Zoom in zoom out animation
HTML-CSS : Exercise-45 with Solution
Using HTML, CSS creates a zoom in zoom out animation.
- Use @keyframes to define a three-step animation. At the start (0%) and end (100%), the element is its original size (scale(1 ,1)). Halfway through (50%) it's scaled up to 1.5 times its original size (scale(1.5, 1.5)).
- Use width and height to give the element a specific size.
- Use animation to set the appropriate values for the element to make it animated.

HTML-CSS: Tips of the Day
How to show multiline text in a table cell?
You want to use the CSS white-space:pre applied to the appropriate <td>. To do this to all table cells, for example:
td { white-space:pre }
Alternatively, if you can change your markup, you can use a <pre> tag around your content. By default web browsers use their user-agent stylesheet to apply the same white-space:pre rule to this element.
The PRE element tells visual user agents that the enclosed text is "preformatted". When handling preformatted text, visual user agents:
- May leave white space intact.
- May render text with a fixed-pitch font.
- May disable automatic word wrap.
- Must not disable bidirectional processing.
