How to build a responsive pricing table using Bootstrap? (Component Build)
Bootstrap's table class is confusing on small screens. Since version 5 removes the default responsive package, containers such as table-responsive-sm need to be explicitly added; iOS needs to add -webkit-overflow-scrolling:touch; it is recommended to use card layout instead of table to implement pricing tables.

How to build a responsive footer with multiple columns in Bootstrap? (Page Elements)
Bootstrap5 multi-column footer uses row-cols- instead of col-md- because it is based on CSSGrid to uniformly control the number of rows and columns to avoid visual misalignment caused by different heights; the copyright column should be independent of the grid, and the main column should be set to min-height to prevent collapse; the logo and social need to be laid out in two rows, and the social link must contain target="_blank" rel="noopenernoreferrer"; the footer link needs to be reset to text-decoration:none.

How to center a div vertically and horizontally in Bootstrap 5?
In Bootstrap5, the centered div needs to be combined with d-flex, justify-content-center and align-items-center, and height classes such as min-vh-100 are set for the parent container; text-center is only effective for inline content and cannot achieve vertical centering of block-level elements; absolute positioning is a backup solution, requiring parent container position-relative, child element position-absolute plus translate-middle.

How to disable the hover effect on Bootstrap buttons?
To disable the :hover style of the Bootstrap button, you need to use an equal or higher specificity selector (such as .btn.btn-primary:hover) to override it, or add a custom class (such as .no-hover) for precise control; at the same time, the :focus and :active states must be taken into account to ensure accessibility.
