Are you looking for the software to do it for you? Or are you trying to do it yourself? If you want the software to do it, first verify it can do it and then read the help files for instructions on how to do it. If you are trying to make the CSS yourself, that link I provided is where you need to start.
all a .css file is a a text file with instructions in it about how the page is rendered. you can use a third party program to do it or you can simply make it in notepad and save it with the extension of .css
I want to ask that hw a CSS file can be created for a website?
Hi, This is simple and also depends on your Editor. This is what you do. In the same way you created your "index.html" file then all you do i make a css file by clicking on "save As" and then in the box that names the file before you finish saving your file you just type this in.
style.css then it saves as a .CSS file ok.
in the same way you created your "index.html" you creat your "style.css" its all down to the last letters after the .DOT ok that makes a file what it is.
