Summary of "HTML text formatting 💭 #3"

Main ideas / lessons

The video teaches basic text formatting in HTML (as a shorter lesson), focusing on common inline formatting tags.
It contrasts normal unformatted text with text wrapped in formatting tags to show how each tag changes appearance.
A key concept is that HTML formatting tags usually require closing tags. Forgetting to close them causes the formatting to continue for the rest of the page/text.
It also demonstrates that some formatting (like ) can apply to larger portions of text (even an entire paragraph) depending on where the opening/closing tags are placed.
