HyperText Markup Language
Concepts
- Why putting
<script> tag at the end?
- Put
<link> to CSS file in the <head>, to avoid FOUC (flash of un-styled content), so that users only see styled content.
- Put
<script> at the end so that page loads faster
- Attributes
- key and values.
class, name things after what they are instead of how they look likeid is unique
- Functionally
<div>, <article> and <section> <nav> are all the same, but try to be specific.
- Do two
<p> tags instead of using <br/>
- Opening/Closing/Self-closing/void tags
- Anchor tags
<a>
- Division
<div>, defined more by what is in it
<span> a container for small piece of text
Events
- A bi-direction process: event is first passing down to target (capturing), then “bubble” up (propagating )
