Hi Dheeraj Bothra,
The container width is defined via the file: ROOT/templates/ja_elicyon/less/variables.less
// Container sizes
// --------------------------------------------------
// Small screen / tablet
@container-tablet: ((700px + @grid-gutter-width));
@container-sm: @container-tablet;
// Medium screen / desktop
@container-desktop: ((930px + @grid-gutter-width));
@container-md: @container-desktop;
// Large screen / wide desktop
@container-large-desktop: ((1140px + @grid-gutter-width));
@container-lg: @container-large-desktop;
// Very Large screen
@container-hd-desktop: (1140px /20) *8 + 1200px;
@container-hd: @container-hd-desktop;
You can change to the value which suits your need.
