Create ACCESSIBILITY-GUIDELINES.md file and add section on semantic html

[GingerKiwi]

This is a low code issue. You just need to be able to read html and markdown. There's a link to a markdown cheatsheet below.

• Create ACCESSIBILITY-GUIDELINES.md file and
• Using markdown create a section with a level two heading '##' for 'Semantic HTML'
• Create a level 3 heading '###' 'Heading Levels' then under this heading provide a quick guideline on:
• (a) how many level 1 headings should be per page (one!)
• (b) when to use level 2, 3, 4 headings
• (c) how headings should be styled (using css not html heading elements)

2. MDN - HTML: A good basis for accessibility
