HTML - Hypertext Mark-up Language

When building a blog using Blogger, you have two modes: Compose or HTML. 

Compose is where you add text, images and video and can see what will be displayed. 

HTML mode is a behind the scenes look at the code behind your blog post, which is written in HTML or Hypertext Mark-up Language. 

It is useful to understand the basics of the HTML language which are quite simple and easy to understand. A good, free and interactive tutorial is provided by W3Schools.com:

In the above link to the W3Schools.com tutorial we added a screen capture image of the tutorial home page, and we made this clickable by changing the A HREF tag in the image to the tutorial web address: 
<a href="https://websterblogs.blogspot.com/2020/06/blgo-home.html">

By default the A HREF tag for an image just lets you access that image in a separate window.

We look at the use of HTML tables in the blog post:
