No matter what I change in my .css file, the page remains the same - what\'s more, neither changing the link tag so that it points to another .css file nor deleting it completel
First check that you making the changes in the right file(believe it happens all the time).
Second if you are playing with the right file check that your changes can be applied. for example use !important
to force the browser to use that CSS style.
Third when you are dealing with JS or CSS Always be sure that you are not working with a cached copy (again it happens all the time)
kindly check this to force your browser to ignore the cache
