HTML-CSS: Clearfix
HTML-CSS : Exercise-17 with Solution
Using HTML, CSS ensures that an element self-clears its children.
- Use the :after pseudo-element and apply content: '' to allow it to affect layout.
- Use clear: both to make the element clear past both left and right floats.
- For this technique to work properly, make sure there are no non-floating children in the container and that there are no tall floats before the clearfixed container but in the same formatting context (e.g. floated columns).
- Note: This is only useful if you are using float to build layouts. Consider using a more modern approach, such as the flexbox or grid layout.

HTML-CSS: Tips of the Day
How to get CSS to select ID that begins with a string ?
[id^=product]
^= indicates "starts with". Conversely, $= indicates "ends with".
The symbols are actually borrowed from Regex syntax, where ^ and $ mean "start of string" and "end of string" respectively.
