Hello jQuery Lesson 3

Using elements without declaring css beforehand

using id selectors for jQuery to grab

You can select children (immediate descendants), descendants (all grandchildren, etc , as well), parents, and grandparents

Item 1 - li:first-child
Item 2
Item 3
- A Hello from the nest - li li: first-child
- Been here a bit
- C

But usually, you will want to find all the li items, so you will use .find instead of .children, so it will search recursively through the tree:

Item 1 - li:first-child
Item 2
Item 3
- A Hello from the nest - li li: first-child
- Been here a bit
- C

jQuery also has its own custom selectors and DOM Traversal Methods that aren't provided by css, like

.first()
eq(x)
next()
prev()
.text('some_text')

Here we use some:

Item 1 - li:first-child
Item 2
Item 3
Item 4
But you really want to use css selectors in the jQuery if you can
