HTML-CSS: Responsive image mosaic

HTML-CSS : Exercise-34 with Solution

Using HTML, CSS creates a responsive image mosaic.

  • Use display: grid to create an appropriate responsive grid layout.
  • Use grid-row: span 2 / auto and grid-column: span 2 / auto to create items that span two rows or two columns respectively.
  • Wrap the previous styles into a media query to avoid applying on small screen sizes.

HTML-CSS: Tips of the Day

A min-height for table, tr or td:

It's not a nice solution but try it like this:

<table>
    <tr>
        <td>
            <div>Lorem</div>
        </td>
    </tr>
    <tr>
        <td>
            <div>Ipsum</div>
        </td>
    </tr>
</table>

and set the divs to the min-height:

div {
    min-height: 300px;
}
