- Using rems/ems instead of px so that the font scales in a uniform way for the webpage or app. So if the user was to change the font size for their browser to something smaller or bigger. All of the font on the website would scale in proportion. So it is very good for accessibility and people who have vision problems. The same applies to everything in the box model too like margin and padding.
- Using developer browser tools like google lighthouse and Accessibility Developer Tools, to audit for performance, accessibility, progressive web apps, and more
- Using buttons for performing actions and anchor tags for leading somewhere
- Using aria-label for buttons with icons as it allows screen readers to give an audio representation of what the button is. As people with disabilities might not be able to see the button clearly or at all
- Using flex box or css grid for tab order. Because if you use floats it breaks the positioning for tab order and keyboard accessibility which works from left to right. Or right to left if you are using a language like Arabic.
- Having an appropriate focused outline colour for focused html elements on a web page. The default colour is blue so if you have a blue button, you could change it to red. Or you could change it to another colour depending on the brand style of your website.
