Ever since we revealed the borders of boxes, you may have noticed that the borders highlight the true shape of an element’s box: square. Thanks to CSS, a border doesn’t have to be square.
You can modify the corners of an element’s border box with the border-radius
property.
div.container { border: 3px solid blue; border-radius: 5px; }
The code in the example above will set all four corners of the border to a radius of 5 pixels (i.e. the same curvature that a circle with a radius of 5 pixels would have).
You can create a border that is a perfect circle by first creating an element with the same width and height, and then setting the radius equal to half the width of the box, which is 50%.
div.container { height: 60px; width: 60px; border: 3px solid blue; border-radius: 50%; }
The code in the example above creates a <div>
that is a perfect circle.
Instructions
In style.css, set the border radius of #banner .content h1
to 15 pixels.
Additionally, try experimenting with other border-radius values and running your code to see the result!
