Dear Muhamad,Yes, many web-related file operations can be done in PHP easily, using functions like file_get_contents and file_put_contents. See the PHP Manual and search the web to answer such basic questions.
In this case, read in the two styles files, then concatenate them into a single string and write out that string. Your HTML file can then link to that new file instead of to the two style files.
