1) In the location where the website is located directory, create a new PHP file.
2) Use a text editor (such as Notepad) to open the newly created PHP file.

tag of the web page or in a separate CSS file.2) Use a text editor (such as Notepad) to open the CSS file that needs to be modified.

- Modify CSS in HTML files
In addition to directly modifying CSS files, we can also directly modify CSS in HTML files. The specific steps are as follows:
1) Find the HTML file that needs to be modified, usually in the root directory of the server's website or in a specified directory.
2) Modify the CSS style in the HTML file as follows:
<!DOCTYPE html> <html> <head> <style> /* 在这里编写需要修改的CSS样式 */ </style> </head> <body> <!-- 在这里添加HTML代码 --> </body> </html>
3. Summary
In website development, PHP and CSS are two very important technologies. . Modifying PHP and CSS files is a common operation in website development. Whether you are modifying existing PHP and CSS files or adding new PHP and CSS files, you need to pay attention to correct syntax and clear logic to ensure the maintainability of the code.
