I am actually in a process of customizing a wordpress new post.I would like to know how do I add the CSS variables to be included in a wordpress New post area? Is it possible for me to include all the CSS variables like how it should appear in normal HTML in a new wordpress Post?Also can you tell me is it also possible to call an external CSS within a wordpress New Post?
I'm not sure if i understand you. But if you want to add styles into simple post you should try just make it local style for example: <p style="color: red;">some text</p> (of course in html post style). Making new external stylesheet's into wordpress is possible but you have to make some php modifications into it, that will allow you to add: <style type="text/css"> </style> Tags
