I am a complete beginner, so I read your article. I learned one thing: "Click on the editor". Thanks. I had been struggling with the HTML markup. I up-vote you for that.

Now I have two tips for other newbies, that I want to share:

Uploading photos:

If you don't already have an online photo, e.g. on your facebook page, then by far the easiest way to get a url to the photo is to use postimg.org. It requires no registration, no password, no email verification, and no details. Just click on "Select Photos", and the URL that you can use on Steemit appears immediately. Do be sure to use the SECOND link down called "Direct Link".

Re-sizing photos

My second tip is to do with resizing photos. They may be too big and you want a smaller one.

Normally an image comes up starting with "https://steemitimages.com/..." followed by a lot of letters and numbers and then the name of the file somewhere in there.

Add the following before it "https://img1.steemit.com/500x500/". You now have "https://img1.steemit.com/500x500/https://steemitimages.com/..." . Your image size is now 500 X 500 or whatever size you chose.

Colours

What I can't figure out, is how to change the colour of text.
