True or False: Class selectors are used to style an entire HTML document.

Class selectors in CSS are not used to style an entire HTML document; rather, they are designed to style specific elements or groups of elements throughout the document. When a class selector is applied to an HTML element, it allows the developer to apply the same styles to multiple elements by assigning the same class name. By doing so, this promotes consistent styling across different parts of the document while still allowing for flexibility.

It's important to note that while class selectors can be used frequently and effectively throughout a document, they do not inherently apply to every element universally. Instead, they must be explicitly assigned to each element that requires those styles. In contrast, element selectors or the universal selector apply styles more broadly. Therefore, the statement regarding class selectors applies only to the elements to which they are assigned and not to the entire HTML document as a whole.
