For PHP programmers, modifying styles is a very common task for website development. PHP files are usually involved in the design and construction of HTML web pages. When modifying PHP styles, you need to understand the following key points, including CSS files, style settings, and editors.

1. CSS file

The CSS file is a text file that controls the appearance of a web page. In PHP files, you can use CSS files to change the styles of elements such as text, background, borders, etc. This can be achieved by referencing an external CSS file or embedding CSS code directly in the HTML markup. Both methods can be used in PHP files.

If you want to use an external CSS file, please follow these steps:

  1. Create a new file named "stylesheet.css" in the directory where the PHP file is located.
  2. Edit the "stylesheet.css" file to change the desired style options.
  3. Add the following lines in the tag of the PHP file:

This links the style sheet to the HTML document, changing the style of all page elements.

2. Style setting

There are two main ways to set styles in PHP files:

  1. Inline style

Inline back styles can be added directly in HTML markup. For example:

This is a center-aligned paragraph.

In this example, the style is applied directly to this paragraph mark without referencing an external CSS file. Although this method is simple, using inline styles in large PHP files is less advisable.

  1. Class style

Class style refers to implementing style changes by defining a CSS style class and then applying the class in HTML tags. For example:

This is a center-aligned paragraph.

In this example, a class called "center" is defined, which is used in HTML tags to apply styles. Class styles are more common than inline styles because they can easily update multiple tags in a PHP file.

3. Editor

For modifying PHP file styles, it is best to use a text editor, such as NotePad or Sublime. These editors come with useful features such as syntax highlighting and auto-completion, as well as code debugging and version control.

In general, modifying PHP file styles involves CSS files, style settings and editors. By learning these key points, you can complete the task of modifying styles more effectively and improve the efficiency of PHP website development.
