Why not place the targeted element inside the brackets?

For example why would this video use something like

header p { color: yellow; }

Rather than

header {

p { color: yellow; }

}

Surely the latter does the same thing? And allows for multiple elements to be targeted without keep declaring header everytime?

You can't nest rules in ordinary CSS, it is a syntax error and causes the entire rule to be ignored. It could certainly be handy, and is in fact implemented in popular pre-processors (like SCSS and Sass).

But for normal CSS, both tags are necessary to create a descendant selector.
