    itch”
  13. The problem with creating products to suit our own needs

    is that the tech industry is not diverse
  14. diversity is the characteristics that make us up as individuals

  15. and all of these characteristics give us unique needs, and

    unique outlooks

  34. Is it because we don’t understand who we’re trying to

    help?
  35. Is it because we just don’t know what to do?

  36. Is it because it’s too hard, and there’s too much

    to think about?
  37. I’ve not got the answers

  38. It’s not fair if the web isn’t accessible

    high- contrast enough. 2. Beware of mega-high contrast too.
  77. Content hierarchy

  78. This is a top-level heading This is a paragraph. It

    has some text in it. It’s a few sentences long. A lot of paragraphs look like this. This is a second level heading. This is a paragraph which has some links to other content and a button that allows you to take action.

    has some text in it. It’s a few sentences long. A lot of paragraphs look like this. This is a second level heading. This is a paragraph which has some links to other content and a button that allows you to take action
  80. Randomly enlarging and colouring text does not make a hierarchy.

  81. 1. Make the content structure clear and consistent. 2. Use

    meaningful headings, labels, lists and other relevant elements for your HTML.
