Getting Started with HTML 2

What is the ID attribute?

The ID attribute can be used to identify a particular

element. In addition to becoming the target of

links, IDs can also be used in CSS and JavaScript.

You can add an ID attribute to almost any tag in

your HTML document.

Are there restrictions on what I can use for an ID?

The value of the ID attribute cannot contain spaces,

but almost more important is that it must be unique

on a page. You cannot have two elements share the

same ID on the same page; if you do, you get

unpredictable results in various browsers. The ID

value is also case-sensitive, so be sure to stay

consistent in how you capitalize it.

4 Scroll in the document to the
point to which you want the
link to go when clicked.
5 In the existing tag at that
point, type id=”?”,
replacing? with the same
identifier you used in Step 2.
Note: The identifier is case-
sensitive, so be sure it matches
exactly.

Note: If no tag exists at the
point to which you want to link,
you can use ,
again replacing? with the
identifier from Step 2. Be sure to
add a closing tag.

● When viewed in a browser, the

link is blue and underlined.

Click it to have the browser

scroll to the other point in the

document.
