A Grid System in CSS refers to a technique that allows developers to create complex and responsive web page layouts through a series of rows and columns. It is a two-dimensional layout system that provides a framework for aligning and organizing HTML elements on the page.
The CSS Grid Layout, which is a native part of the CSS specification, enables the creation of layouts that were difficult or impossible to achieve with older CSS layout techniques like float-based layouts, inline-blocks, or table layouts. With the CSS Grid, you can define a grid structure on the parent element (the grid container), and then place child elements (grid items) into the grid cells defined by that structure.
Key features of the CSS Grid System include:
Two-Dimensional Layout: Unlike Flexbox, which is a one-dimensional system (either in rows or columns), the Grid system can handle both rows and columns simultaneously[1][2].
Flexibility: You can create grid columns and rows with fixed sizes using units like pixels or flexible sizes using percentages or the new fr (fraction) unit[2][3].
Placement Control: Items can be placed in specific locations on the grid using line numbers, names, or by targeting an area of the grid. This allows for precise control over the layout[2].
Automatic Placement: Grid also contains an algorithm to control the placement of items that are not given an explicit position, which can help in creating dynamic layouts without specifying the position of each item[2].
Alignment and Overlapping: Grid provides alignment features to control how items align within a grid area and how the entire grid is aligned. More than one item can be placed into a grid c...
