Be mindful of contrast. What looks good to you may not be readable for others. Text contrast is a good thing!
Support all navigation modes. Some people will interact with your interface using assitive technologies and/or a keyboard. Build your interface with these different modes in mind (for example, by setting the `tab-index` attribute on all interactive elements that aren't interactive by default).
