How to Select Elements with Partial IDs in CSS?

Partial ID Value Selection in CSS

Problem

When elements are generated dynamically using programming languages like PHP, it can become challenging to select specific elements using incomplete ID values. This situation arises when the entire ID name is unknown, but only a partial string is available for identification.

Explanation

ID selectors in CSS require complete ID names to function effectively. However, the need to select elements based on partial ID strings prompted the introduction of substring attribute selectors. This solution allows for precise identification of elements based on specific string patterns.

Solution

To select elements with partial ID values, employ substring attribute selectors instead of ID selectors. The syntax for these selectors is as follows:

[attribute^="string"]

where attribute represents the ID attribute, and string indicates the partial string to match against.

In your case, you can use the following selectors to achieve desired results:

div[id^="as_"]

div[id^="bs_"]

These selectors would target all elements with IDs that start with "as_" and "bs_", respectively.

Alternative Solution

As an alternative to using partial ID substring attribute selectors, you can also utilize class attributes if available. Each element group can be assigned a shared class, enabling element selection based on that class rather than individual IDs. This method simplifies selection and can be easily achieved through PHP code used to generate element IDs in the first place.
