Can CSS Wildcards Streamline Styling of Dynamic Classes with Unique Identifiers?

Utilizing CSS Wildcard for Dynamic Class Styling

In styling HTML elements, it's common to encounter unique identifiers alongside the primary class. In the scenario provided, multiple divs are styled using the class "tocolor," but each requires an additional unique identifier, such as "tocolor-1," "tocolor-2," and so on.

The question arises: is there a way to streamline this by using a wildcard () in the CSS selector? The initial attempt using ".tocolor-" yielded no results.

The solution lies in leveraging attribute selectors. Attribute selectors allow you to target elements based on their attributes, such as their class. In this case, the following selectors would accomplish the desired effect:

div[class^="tocolor-"], div[class*=" tocolor-"] {
    color:red;
}

The "[class^="tocolor-"]" selector targets elements whose class attribute starts with "tocolor-," while the "[class*=" tocolor-"]" selector targets elements whose class attribute contains the substring "tocolor-" following a space character.

Breakdown of the Selectors:

• "[class^="tocolor-"]": Matches elements with class attributes that begin with "tocolor-," such as "tocolor-1," "tocolor-2," and so on.
• "[class*=" tocolor-"]": Matches elements with class attributes that contain the substring "tocolor-" immediately preceded by a space character, such as "tocolor-1," "test tocolor-2," and so on.

By utilizing these attribute selectors, you can apply the desired styling to multiple elements with different unique identifiers using a single class selector. This simplifies the CSS code and enhances maintainability.
