So that’s basically it for simple classes. But there’s another attribute very similar to a class that you should understand, and understand when to (and not to) use, called an id. Understanding id (vs. class) Similar Ids can be used to

Because a document can only have one element with a particular ID, any rule with an ID selector will apply only once. Depending on how your document is structured, just pick one and run with it. Nested Selectors. Your selectors do not have to consist of single HTML types, class names, or ID values.

. – is a class selector that target elements with the correct class attribute. # – is an id selector that styles the element with the specified id attribute. When I was initially learning HTML and CSS I was hit by this stumbling block a number of times and knowing this distinction between class selectors and id selectors can save you a lot of time.

En effet, l’id ne doit désigner qu’un seul objet du document. On peut bien sûr définir autant d’id que l’on veut dans la feuille de style, mais il faut qu’ils soient uniques dans la page html.

Get Element by Matching the Value of the “id” Attribute. document. getElementById(id_string) Return a non-live element object. Returns null if not found. const x = document. getElementById (“xyz”); x. style.color = “green”; Note: element id must be unique per HTML file.
