• If the element with a class of alert also has a class of stop, make the background red.
• If the element with a class of alert also has a class of go, make the background green.

In this example, try making the following changes without adding to the HTML.

• Style links, making the link-state orange, visited links green, and remove the underline on hover.

In this task try the following:

• Make any paragraph that directly follows an h2 element red.

You can practice these examples in the Interactive Editors mentioned above.

If you would like your work assessed, or are stuck and want to ask for help:

1. Put your work into an online shareable editor such as CodePen, jsFiddle, or Glitch. You can write the code yourself, or use the starting point files linked to in the above sections.

2. Write a post asking for assessment and/or help at the MDN Discourse forum Learning category. Your post should include:

   • A descriptive title such as "Assessment wanted for Selectors skill test 1".
   • Details of what you have already tried, and what you would like us to do, e.g. if you are stuck and need help, or want an assessment.
   • A link to the example you want to be assessed or need help with, in an online shareable editor (as mentioned in step 1 above). This is a good practice to get into — it's very hard to help someone with a coding problem if you can't see their code.
   • A link to the actual task or assessment page, so we can find the question you want help with.
