The HTML id attribute is used to specify a unique id for an HTML element.
You cannot have more than one element with the same id in an HTML document.
Using The id Attribute
The id attribute specifies a unique id for an HTML element. The value of the id attribute must be unique within the HTML document. The id attribute is used to point to a specific style declaration in a style sheet. It is also used by JavaScript to access and manipulate the element with the specific id. The syntax for id is: write a hash character (#), followed by an id name. Then, define the CSS properties within curly braces {}.
Difference Between Class and ID
A class name can be used by multiple HTML elements, while an id name must only be used by one HTML element within the page.
HTML Bookmarks with ID and Links
HTML bookmarks are used to allow readers to jump to specific parts of a webpage. Bookmarks can be useful if your page is very long. To use a bookmark, you must first create it, and then add a link to it. Then, when the link is clicked, the page will scroll to the location with the bookmark. This was previously implemented in PR #11!
