The CSS Grid
CSS Grid, also known as "Grid Layout," is a powerful layout model in CSS (Cascading Style Sheets) that allows you to create complex two-dimensional layouts with rows and columns. It provides fine-grained control over both the placement and alignment of elements within a container, making it an excellent choice for designing grid-based layouts for web pages and applications.
Unlike Flexbox, which is primarily designed for one-dimensional layouts (either rows or columns), CSS Grid enables you to create layouts that are more like tables or grids, with rows and columns working together.
