Task 1

In this task, we want you to add a background, border, and some simple styling to a page header:

  1. Give the box a 5px black solid border, with rounded corners of 10px.
  2. Add a background image (use the URL balloons.jpg) and size it so that it covers the box.
  3. Give the <h2> a semi-transparent black background color, and make the text white.

Your final result should look like the image below:

Images shows a box with a photograph background, rounded border and white text on a semi-transparent black background.

Task 2

In this task, we want you to add background images, a border, and some other styling to a decorative box:

  • Give the box a 5px lightblue border and round the top left corner 20px and the bottom right corner 40px.
  • The heading uses the star.png image as a background image, with a single centered star on the left and a repeating pattern of stars on the right.
  • Make sure that the heading text does not overlay the image, and that it is centered — you will need to use techniques learned in previous lessons to achieve this.

Your final result should look like the image below:

Images shows a box with a blue border rounded at the top left and bottom right corners. On the left of the text is a single star, on the right 3 stars.
