IntroduCtIon
As we have already discussed in previous chapter about HTML. Hypertext Markup Language 
is used by web browsers that represents the data. In this chapter, we will cover advance 
formatting tags of HTML such as Lists, inserting images, videos, music and creating links 
between two or more webpages.
1. HtMl lists
Lists provide the information in a structured and easy to read format. The data item on 
the webpage can catalogued or indexed. The index that is formed using numbers like 
1,2,3,…or symbols like ?, b, 8 is called a List in HTML. These lists help in formatting 
the data and put them in a particular order. There are three types of lists that you can 
use in HTML. They are: 
 ? UL - creates an unordered or bulleted list 
 ? OL - creates an ordered or numbered list 
 ? DL - creates a definition or glossary list 
The first two are very similar in structure, while definition lists have a unique setup. To create 
either kind, first specify the start of a list and then identify each line item in the list
1.1 unordered list <ul> ….</ul>
It classifies the data items that have equal importance i.e. none of the data items are 
ranked. They are identified by a symbol. It may be a ? square, a ? circle or a ? disc. The

attribute TYPE helps in using the symbols to create a list. This attribute takes the value 
as the name of the symbol.
<ul type=”square”>
<ul type=” disc”>
<ul type=” circle”>
This is a container tag. It has both the opening and the closing tag. However the closing tag 
is optional. The listing is created under it using the <li> tag. Again <li> tag is a container 
tag. The data item to be listed is input between the opening <li> and the closing </li> tag 
as shown in the following example:
For Example1:
<body>
    <ul>
        <li>apples </li>
        <li>oranges</li>
        <li>guava </li>
    </ul>
</body>
In the above code the data item comprises of the fruits that have equal importance to the 
user. They are listed using unordered list. When you do not use the attribute named type, 
the default symbol is used i.e. disc. The output of the above code is:

Definition lists (<dl>) are the list elements that have an array of tags. The list prepared 
by <dl> tag is similar to a dictionary. The other tags used with this are <dt> to define the 
definition term and the <dd> for the definition of the list item.
