Gutters, No Gutters, Container, No Container, Container Fluid

  Issue #3199224: Fixed Container type and Gutters layouts rendering

In my opinion to make use of: Bootstrap 5 Horizontal gutters and have the logic of no-container

.gx-* classes can be used to control the horizontal gutter widths. The .container or .container-fluid parent may need to be adjusted if larger gutters are used too to avoid unwanted overflow, using a matching padding utility. For example, in the following example, we’ve increased the padding with .px-4

• Issue #3201141: Change .px-4 to use the right .gx-* CSS class from Bootstrap 5 to be used with Bootstrap 4 using the gutter size in px, not in rem to be inline with Bootstrap 4

• Issue #3201146: Backport .gx- to Vartheme BS4 from Bootstrap 5 to be used with Bootstrap 4 using the gutter size in px, not in rem to be inline with Bootstrap 4
