HTML-CSS: Triangle

HTML-CSS : Exercise-32 with Solution

Using HTML, CSS creates a triangular shape with pure CSS.

  • Use three borders to create a triangle shape.
  • All borders should have the same border-width (20px).
  • The opposite side of where the triangle points towards (i.e. top if the triangle points downwards) should have the desired border-color. The adjacent borders (i.e. left and right) should have a border-color of transparent.
  • Altering the border-width values will change the proportions of the triangle.

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;
}
