CSS Grid Layout excels at dividing a page into major regions or defining the relationship in terms of size, position, and layer, between parts of a control built from HTML primitives. Like tables, grid layout enables an author to align elements into columns and rows
Grid control is used to display/edit/Delete/insert rows of records
If you mean the 'lines' that make up the grid, then they are co-ordinate sections. For example: if I told you to go to A2, that section may display a piece of China.
The grid is a rectangular pattern of dots or lines that extends over the area you specify as the grid limits. The grid displays dots only when the current visual style is set to 2D.
IF you mean 'what DOES display mean' - display means 'show'

To remove the grid in your background, you typically need to access the settings of the program you're using. Look for options like "View" or "Grid Settings" and uncheck or disable the grid display. In graphic design software, you might also find a shortcut key to toggle the grid on and off. If you're working with a specific application, consult its help documentation for precise instructions.
