15.6. Exercises: CSS

Note

We built a website for you to test your CSS knowledge! To allow you to view your work in its own browser tab, we saved the starter code in repl.it.

Complete the exercises, then follow your teacher’s instructions about how to submit your work.

Add the following style rules to the website. It’s OK to look back in the chapter, but try to complete as many of the tasks as possible before you check!

15.6.1. External CSS

Add element, class, and id selectors to the style.css file to do the following:

  1. Change the background color of the whole page to yellow.
  2. Change the text color to green for all paragraphs, and set font-family to Courier.
  3. Change all h1 elements to 48px font size and underline the text. (Bonus: Make it a wavy underline). Change all h2 elements to 36px font size. Also, decorate the text with both an overline and an underline.
  4. Align all text to the center of the page.
  5. Instead of aligning all of the text to the center, use a CSS class to align only the headings to the center of the page.
  6. Create a class called fancy-text with a font-family of cursive. What happens when you apply this class to a section, a paragraph, or a heading?
  7. Can you place more than one value in the class attribute, like class="class_name_1 class_name_2"? Try it to find out!
  8. Change the font color of the element with id="cool-text" to blue.
  9. Use a CSS id to change the items in the ordered list to a color and size of your choosing. Remember, you can only add that id attribute to ONE tag.
  10. Use a class or id to put an interesting border around one of the sections.

15.6.2. Internal CSS

  1. Add an internal p selector that sets the font-family to Helvetica and the text color to slategray.
    1. Does the internal element selector override the external one?
    2. Check <p class="fancy-script">. Does the internal element selector override the external class?
  2. In head, move the <link> element below the closing </style> tag. Does changing the order of the two elements matter?
