is there any chnage in bootstrap grid system after adding meta tag code example

Example: bootstrap Responsive

Responsive containers are new in Bootstrap v4.4. They allow you to specify a class that is 100% wide until the specified breakpoint is reached, after which we apply max-widths for each of the higher breakpoints. For example, .container-sm is 100% wide to start until the sm breakpoint is reached, where it will scale up with md, lg, and xl.

Copy
100% wide until small breakpoint
100% wide until medium breakpoint
100% wide until large breakpoint
100% wide until extra large breakpoint
// Extra small devices (portrait phones, less than 576px) // No media query for `xs` since this is the default in Bootstrap // Small devices (landscape phones, 576px and up) @media (min-width: 576px) { ... } // Medium devices (tablets, 768px and up) @media (min-width: 768px) { ... } // Large devices (desktops, 992px and up) @media (min-width: 992px) { ... } // Extra large devices (large desktops, 1200px and up) @media (min-width: 1200px) { ... } Since we write our source CSS in Sass, all our media queries are available via Sass mixins: // No media query necessary for xs breakpoint as it's effectively `@media (min-width: 0) { ... }` @include media-breakpoint-up(sm) { ... } @include media-breakpoint-up(md) { ... } @include media-breakpoint-up(lg) { ... } @include media-breakpoint-up(xl) { ... } // Example: Hide starting at `min-width: 0`, and then show at the `sm` breakpoint .custom-class { display: none; } @include media-breakpoint-up(sm) { .custom-class { display: block; } } We occasionally use media queries that go in the other direction (the given screen size or smaller): // Extra small devices (portrait phones, less than 576px) @media (max-width: 575.98px) { ... } // Small devices (landscape phones, less than 768px) @media (max-width: 767.98px) { ... } // Medium devices (tablets, less than 992px) @media (max-width: 991.98px) { ... } // Large devices (desktops, less than 1200px) @media (max-width: 1199.98px) { ... } // Extra large devices (large desktops) // No media query since the extra-large breakpoint has no upper bound on its width Once again, these media queries are also available via Sass mixins: Copy @include media-breakpoint-down(xs) { ... } @include media-breakpoint-down(sm) { ... } @include media-breakpoint-down(md) { ... } @include media-breakpoint-down(lg) { ... } // No media query necessary for xl breakpoint as it has no upper bound on its width // Example: Style from medium breakpoint and down @include media-breakpoint-down(md) { .custom-class { display: block; } } $zindex-dropdown: 1000 !default; $zindex-sticky: 1020 !default; $zindex-fixed: 1030 !default; $zindex-modal-backdrop: 1040 !default; $zindex-modal: 1050 !default; $zindex-popover: 1060 !default; $zindex-tooltip: 1070 !default;
