Layout issue

Hi Team,

There are many issues with the layout.

On the template level, there's an overflow of the containers on the right

When I try to do layout on the smaller screen (tablet) the container is not even fully visible in the section.

Grid.less file having this code

@import (once) "/libs/wcm/foundation/clientlibs/grid/grid_base.less";

/* maximum amount of grid cells to be provided */
@max_col: 12;

/* default breakpoint */
.aem-Grid {
  .generate-grid(default, @max_col);
}

/* phone breakpoint */
@media (max-width: 768px) {
  .aem-Grid {
    .generate-grid(phone, @max_col);
  }
}

/* tablet breakpoint */
@media (min-width: 769px) and (max-width: 1200px) {
  .aem-Grid {
    .generate-grid(tablet, @max_col);
  }
}

/* force showing hidden components in unhide mode */
.aem-GridShowHidden > .cmp-container > .aem-Grid > .aem-GridColumn {
  display: block !important;
}
