all right let's talk about list elements that allow us to define uh lists in html so we have three different types we're going to talk about unordered ordered and description lists or like sort of data definition lists um so the first one we'll start with is an ordered list this is like you want a list of things that has a number a number next to it one two three four or whatever so the tag for the ordered list for um for both unordered and ordered lists the elements of each item in the list is going to be an li but for an ordered list the parent is going to be ol okay so we have ol is our ordered list and then inside we're going to have an li and we might have foo foobar baz baz quacks these are all sort of standard standard variable names for examples in computer science so we have foobar bazquacks um like with two use or whatever so now we have this ordered list note that i didn't have to add one two three four five here and it automatically just picked up the number and added that there's a couple cool things you can do with attributes on an ordered list you can say start you can set the attribute start value so if we want to start this at 1020 we could start there so that our ordered list started at 1020. um you can also set it so that it uses roman numerals or alphabet alphabetical numbers by setting the type so if we set the type to a lowercase i that'll use eyes or roman numerals if we send to it a capital i that'll use capitalized roman numerals we can also set it to an a which will use the alphabetical what's really cool is you can combine type with start value so we could say like start this at number three or something and then rather than starting from a we're going to start from c so that's that's kind of cool and those are those are all tricks that we can do with the ordered list let's take a look at the next kind of list that's an unordered list so if we have a ul tag inside again the items are going to be the same in fact i'm just going to copy and paste the same items here because we can use the same li tags within an unordered list now if we refresh the page we'll see the unordered list here and by default it's just kind of a bulleted list and the type of the bullet that we're seeing here is disk that's like the name of the that type of bullet but we can set the type to other things if we wanted we can set the type to like circle or square or none and that would just remove it completely and commonly like uh css resets or like css styles will just remove this remove the the style from an ordered list so that it just looks like this and then maybe might be styled differently with css so let's put it back to circle and take a look at the next type of list which is a description list so this one is the tag name is dl and a description list is generally used for like defining some sort of term right so if you have a maybe a dictionary right you want to define what each of the terms mean so let's try to define what foo means so we'll get we're going to have a tag called dt for the data term or the description term and we might say foo and then we'll have um dd which is the definition of foo foo is a common variable name in cs okay so then we might want to do the same thing with bar bar common second variable name and cs okay so we refresh the page we can kind of see what that would look like so this is what a um a data or a description list might look like so this is much less common so i've probably only used the description list like once or twice ever in in all of my time writing web applications but unordered list and order list super common definitely great to know i would say probably the most common of these three lists is the unordered list awesome so that wraps up lists in the next episode we're going to dig into forms how do we build form elements that can collect data uh from from the user so we're really just going to focus on the html for building a form and then in the future we can we can go down the road of actually collecting that data and storing it in a database and taking actions on it so let's look at forms next you
