What is the best way to ensure a NavBar stays at the top of the page when it is not collapsed?

I have integrated a NavBar using Bootstrap 5, which functions flawlessly. However, I am facing a specific issue that I haven't been able to resolve yet:

When a user increases their screen size to <300%, it triggers the collapse button to appear. If they continue to increase the size to 500%, the collapsed NavBar covers the entire screen and prevents viewing the bottom part of the NavBar. The main problem arises from the fact that the NavBar is fixed at the top of the site, making scrolling ineffective. This forces the user to view a truncated NavBar until they navigate to another page. While this may be a rare scenario, I believe there are various solutions available. One potential option could be designing a new custom layout for the collapsed NavBar or restricting the "fixed-top" attribute only to the non-collapsed state. However, implementing the best solution remains uncertain.

Answer №1

To make adjustments to the top section, it is common practice to use Bootstrap's fixed-top class. However, if you only want the top section to be fixed when it's expanded, you can define a custom class like fixed-top-lg (or sm or md - depending on your preference).

Additionally, ensure that there is enough spacing for the section or container below your navbar to maintain consistent spacing - refer to the provided code snippet for more details.
