Lesson 1: Basic HTML Tags
(About the Exercises)

Common Mistakes
When building the exercises, here are some common mistakes to avoid:

1. Using an open tag when you meant to use a closing tag.
2. Omitting a closing tag.
3. Forgetting to end a tag with the ">" character.
4. Failing to save your file after you've made changes.
5. Forgetting to reload/refresh your page after you've updated the code.
6. Using an attribute as a tag. For example, <size="5"> is not a tag, but <hr size="5" /> is.
