How to edit the html code in wordpress theme
<p>I have a wordpress blog and I want to customize it a bit. I know CSS and HTML but not php. from what I understood the php should call the html code, so if i could find the html code it will be easy for me to customize my blog.</p>

<p>The thing is, I can't find the html code. I looked at appearance --> editor and it is all php files and one css. </p>

<p>Someone has an idea how to edit the html code/find it ?</p>

<p>thanks</p>
