We've all created lists before.
0:00
Grocery list, a list of our
favorite restaurants and movies, or
0:02
a list of guest we want
to invite to a party.
0:05
Lists are an important component of web
design and front end web development.
0:07
Just about every website or
application on the web uses lists
0:11
to display navigation menus, shopping cart
items, movie listings and so much more.
0:14
HTML provides three elements for
creating list, <ul> for unordered list,
0:20
<ol> for ordered list, and
<dl> for description list.
0:25
The DL element is used to create groups of
terms in descriptions, like in a glossary.
0:30
It's not as common as the other two lists,
so
0:35
I'm not gonna cover it in this course,
but I've posted resources and
0:37
examples of description lists in
the teacher's notes of this video.
0:40
Now let's create a list of the different
sections that will make up our website,
0:44
Home, About, Articles, and Contact.
0:48
We'll mark up the list
using the UL element.
0:50
UL stands for unordered list.
0:53
So, back in our index.html file,
below the main heading and paragraph,
0:55
add a set of opening and
closing <ul> tags, and
1:01
inside the ul write Home,
then below that About,
1:05
Articles, and Contact.
1:10
When you think of a list, you imagine each
item in the list placed on its own line.
1:14
Well, the UL tag, by itself,
will not display a typical list.
1:19
As you can see here in the browser,
all items are placed on the same line.
1:23
So, to specify the individual
items of a list,
1:26
you place them inside LI tags,
which stands for list item.
1:29
So, back in our list,
let's add opening and
1:34
closing <li> tags around each menu item.
1:36
Each LI now represents an item in
the list, and LI tags, when placed or
1:54
nested inside a UL tag,
are displayed using bullet points.
1:59
Again <ul> stands for unordered list,
2:06
meaning the order in which the items
are displayed is of no significance.
2:08
So for example, if you're creating
a shopping list, the order in which
2:13
the items appear doesn't matter,
you just need to buy every item listed.
2:16
But if you need to list
items in a specific order,
2:20
like step by step instructions of a recipe
or a list of your top 10 favorite movies,
2:23
then you can use an ordered
list using the <ol> element.
2:28
So we'll change the opening
<ul> tag to an <ol> tag, and
2:32
we'll do the same for the closing tag.
2:37
We'll give it a save, and
as you can see in the browser,
2:38
the <ol> element uses numbers instead of
bullet points in order from one to four.
2:41
Ordered and
2:47
unordered list can also be nested inside
other lists to create multi-level lists.
2:48
So back on our list, I'll change
the <ol> tags back to <ul> tags.
2:53
Then I'll expand the contact list item,
and below the word contact
2:59
let's nest an unordered list by typing
a set of opening and closing <ul> tags,
3:05
and in this list I'll create three list
items but you can add as many as you like.
3:10
So, I'll start with Email.
3:16
Below that I'll create a list item for
Phone, and a list item for Address.
3:21
I'll give the file a save, and over in the
browser, notice how when you nest a list,
3:31
the browser adds indentation
to give the list structure.
3:37
So notice how now our list
resembles an outline.
3:42
So to recap, unordered lists display
bullets, ordered lists display numbers,
3:44
and you're able to nest
lists inside list items and
3:50
use a combination of <ul> and
<ol> tags to create a list.
3:53
Now I'm going to delete
the nested UL inside the main UL.
3:57
But to let you experiment with lists on
your own I've posted a tech snippet in
4:02
the teacher's notes about
the top VR resources.
4:06
So go ahead and add that text
below the blog entries here, and
4:10
turn it into an ordered list and
4:14
feel free to pause this video while
you grab the text and create the list.
4:16
So first, I'll paste the text into
the page just above the closing body tag.
4:20
So this new Top VR Resources
content is indirectly related
4:30
to the Latest VR Articles section.
4:34
So its heading shouldn't hold equal or
4:37
a more importance than
the Latest VR Articles h2.
4:39
So we'll mark up the resources heading
as a sub-heading of the H2 using an H3.
4:43
Then, we'll place the list inside
an ordered list by wrapping it
4:53
inside a set of <ol> tags, And
4:59
we'll place the items inside a <li> tags.
5:04
All right, let's save our file, refresh
the browser, and there you have it,
5:20
our top VR resources list.
5:25
So in the next video,
I'll teach you about links,
5:26
the most important feature of the web.
