I have 3 different web templates each with their respective assets (css, js, etc.). What I want is to join them in one, I was trying with frames but it does not work out because the window starts. Try PHP saving each web into a variable with a proper function of PHP called file_get_contents and then print for one another on, however when I try it will distort and confuse the codes of the assets and the web shows me very different disordered.
Help please, I know that this is something very easy for many, however I have a client that came up with 3 different and good templates!
