Good navigation is simple, clear, and straightforward. It's vital on mobile, where users expect to complete their tasks in the least possible amount of time.
What can improve navigation?
Show the name of the current page. To navigate successfully, users should always be able to answer the question "Where am I?"
Break down big tasks into easy steps to minimize the cognitive load. For example, instead of offering a long checkout form, ask users to fill in information over multiple screens: their shipping address, billing information, and order confirmation can each be on separate screens.
Emphasize important information. You can do so by increasing the font size, adding white space, and ensuring that the element's color contrasts well with the background color.
