Answer №1

If you set the left and right margin to auto, it might just do the trick! Give this a shot - try using mx-auto which sets the margin on the x-axis (left and right) to auto!

Answer №2

Bootstrap's flexbox grid system is ideal for constructing layouts with ease. With its 12 column layout and multiple tiers, it functions like any other CSS class. Bootstrap conveniently provides predefined classes to streamline the process.

For instance:

<div class="col-lg-12">
      This will occupy the entire screen space
    </div>

All you have to do is center your content within the div to ensure it takes up the desired area while maintaining a centered alignment. The "lg" represents a large area in this case, but there are various options available that can be paired together to adapt to different screen sizes. These pre-defined col types make referencing them simple.

Utilizing this grid system guarantees responsiveness for whatever you're creating, making it a pleasure to work with. I highly recommend exploring its capabilities.
