What is CSS selector syntax?

Answer 1

Let us say you have a div tag like this.

<div id="divId" class="divClass"></div>

This is the tag selector. This will affect all div elements.

div {

}

This is the id selector. This will affect the element with the given id.

#divId {

}

This is the class selector. This will affect elements with a specific class.

.divClass {

}
