Hi, I am a designer and I design custom themes for my clients and I have been trying to convert a plain html site into a wordpress theme. Can someone direct me to a link or page where I can find the different code that is required in the different files like index.php, single.php etc. I have read numerous tutorials but they eventually build up into the authors own look of their theme. I want to be able to create any theme but first I have to know the code that has to be in header.php, index.php etc. in order for wordpress not to crash.
