From WPHub: In today’s coding generation, HTML is a very basic language. For that reason alone, I am going to call this a beginner’s tutorial on HTML and its use in WordPress. There are several HTML tags that are vital for customizing content in a WordPress blog. I will concentrate on things that you cannot do with the WYSIWYG editor. The WordPress WYSIWYG editor is the tool in the WordPress admin that allows most WordPress users to know little or no HTML code at all and still make a somewhat decent looking blog post or page. However, if you know the basics of HTML that I will cover here, there are more content styling options available to you when developing a post or page in WordPress. That’s why it is essential to know a little HTML when adding content to your WordPress blog or website.
