CSS Reference Guide: Unveiling the Meaning of the Dot

The period or dot (.) is a ubiquitous symbol in CSS, serving various purposes in defining styles for HTML elements. Let's delving into its significance:

Selector Starting with a Dot

A single dot at the beginning of a selector, such as .work-container, indicates that the rule applies to elements with the specified CSS class. In this case, it targets all elements with the class "work-container."

Two Dotted Selectors Separated by Space

When two dot-separated selectors are separated by a space, as seen in .work-container .h3, the rule targets elements that simultaneously possess both the parent and child classes. For example, it selects elements with the class "h3" that are descendants of elements with the class "work-container."

Two Dotted Selectors Without Separation

In contrast, when two dot-separated selectors are written without any space, as in .name1.name2, the rule targets elements that possess both of the specified classes. This differs from the previous case, where the elements needed to inherit classes from a parent.
