Creating a full-width header in React: A step-by-step guide

I'm facing an issue with the header I created - I want it to be 100% width of the screen, but when I decrease the screen size, it doesn't scale accordingly. Here's my current CSS:

 <Box
      style={{
        backgroundColor: "RGB(46, 180, 195)",
        height: "60px",
        padding: "12px",
        width:"100vw",            
        position: "sticky",
        top: 0,
      }}>

While the header fits the screen when the size is normal, it fails to adjust properly when I reduce the screen size. I've also tried using a percentage value for width without any success.

Answer №1

To ensure the Box component resizes accordingly, apply a "width 100%" style to all parent components containing it. This will adjust the Box's width relative to its parent's size. If the parent does not have a width of 100% or 100vh, the Box component will not resize as expected.
