What\'s the Difference: Single, Double, and Multi-Dot Selectors in CSS?

Unveiling the Role of the Dot in CSS

In the realm of CSS, the humble dot holds a significant meaning that can alter the targeting capabilities of selectors. Let's delve into the complexities of how the dot operates in different scenarios.

Single Dot: Class Selector

A selector that commences with a dot, such as .work-container, designates a class name. This implies that the styling rules will apply to any HTML element that possesses that specific class.

Two Dots Separated by Space: Descendant Selector

A selector with two dots separated by a space, like .work-container .h3, represents a descendant selector. It targets elements that bear the second class name while also being descendants of elements with the first class name.

Two Dots Without Space: Multiple Class Selector

Conversely, a selector with two dots without a separating space, such as .name1.name2, signifies a multiple class selector. It applies the styling to elements that simultaneously possess both the first and second class names.
