Good UI design allows you to create a user interface that is both functional and beautiful. Well-designed websites are easier to use and a pleasure to interact with. It removes obstacles and barriers to the core features of your product. Here are some small tips I've picked up along the way that are timeless and widely applicable.

Inline links in a paragraph may need help distinguishing themselves as interactive.
However, if you have a list of items that are links, it is often understood by users that they are clickable.

Use font size, font weight, color, and spacing to draw attention to the more important aspects of your UI.
