Answer

Answer:

Cascading Style Sheets (CSS) are a style - sheet language used for describing the presentation of a document written in HTML (or XML). Their primary function is to separate the content of a web page from its visual presentation.

Two effects on programming:

  1. Code Reusability: CSS allows styles to be defined once and reused across multiple elements or pages. For example, a single class can be applied to multiple HTML elements to give them the same visual style.
  2. Easier Maintenance: When a visual change needs to be made, it can be done in one CSS file instead of having to modify each individual HTML element's style attributes. This saves time and reduces the chance of errors.

This is a benefit to the programmer as it makes the development process more efficient. Code reusability reduces the amount of redundant code, and easier maintenance means that updates and changes can be implemented more quickly and with less effort.

Brief Explanations:

CSS separates content and presentation. Reusability cuts down on redundant code. Easier maintenance streamlines updates.
