How can I vertically center a child container in a section that fills the remaining viewport after the navbar, which reduces the section height?
TL;DR
- Ensure the navbar is at the top, and the section fills the remaining viewport.
- Set the section height to
100vhand adjust for navbar height with top padding/margin orcalc(100vh - [navbar-height]). - Use Flexbox to center the child container vertically within the section.
To vertically center a child container in a section that fills the remaining viewport after accounting for the navbar height, follow these steps:
1. Structure Your Layout Correctly
- Ensure the navbar is positioned at the top of your page.
- Create a section immediately below the navbar intended to fill the remaining space.
2. Set Section Height to Fill Viewport
- Select the section in the Webflow Designer.
- Set the Height to
100vhto ensure it fills the entire viewport height.
3. Adjust for the Navbar Height
- Apply a top padding or margin to the section equivalent to the navbar height or ensure the section position subtracts the navbar height.
- Alternatively, subtract the navbar height using CSS by setting Height to
calc(100vh - [navbar-height]).
4. Use Flexbox to Center the Child Container
- Select the section in the Webflow Designer.
- Set the section's Display to Flex.
- Choose Vertical Alignment to Center. This will center the child container both vertically and horizontally by default if no other alignments are specified.
5. Check Responsiveness
- Preview the design in various devices and viewport sizes to ensure consistent vertical alignment across all devices.
Summary
To center a child container in a section that adjusts to the remaining viewport after a navbar, set the section height considering the navbar and use Flexbox with vertical centering. This method ensures the container aligns perfectly regardless of screen size.
