Best Practices

  • Use a reasonable width value for the border to avoid creating borders that are too thin or too thick.
  • Avoid using too many different border styles on a single page as it can be visually overwhelming.
  • Make sure the border style matches the overall design and layout of your site.
  • Use the border-bottom property in conjunction with the border-bottom-width and border-bottom-color properties to fully define the bottom border of an element.
  • Consider the layout and hierarchy of your content when deciding which border style to use. For example, you may want to use a solid border for header elements but a dotted border for subheadings.
