Study Notes

Grid Layout Calculation

Flex Factor Calculation: The leftover space in a grid column is calculated as * (leftover space / sum of all flex factors).
Example Calculation with Pixels: For a grid of width 600px defined as grid-template-columns: 200px 2fr 1fr, the flex values can be determined:
- 1fr = 1 * ((600px - 200px) / (2 + 1)) = 133px
- 2fr = 2 * ((600px - 200px) / (2 + 1)) = 267px

Grid Functions and Sizes

CSS Grid Functions: Functions such as minmax() offer flexibility in defining track sizes.
Minimum and Maximum Sizes:
- The syntax grid-template-columns: minmax(auto, 50%) 1fr 3rem sets column sizes with defined limits; the first column stretches automatically but does not exceed 50% of the container width.
- Row heights can similarly use minmax(10rem, auto) to ensure a minimum height while allowing for growth.

Shorthand for Grid Layouts

Shorthand Syntax:
- The shorthand grid-template-columns: repeat(3, 1fr) creates three equally sized columns.
- For rows, grid-template-rows: repeat(4, 10rem) generates four rows each 10rem tall.

Grid Spacing

Grid Gaps: The grid-gap property, e.g., grid-gap: 5rem 1rem, creates space between grid rows and columns, but not at the grid container's edges.

Explicit vs Implicit Grids

Explicit Grid: Defined by set rows and columns using grid-template-rows and grid-template-columns, constraining placement within specified cells.
Implicit Grid: Automatically generated when there are more grid items than defined cells, thus creating new tracks and lines to accommodate overflow.

Controlling Overspill in Grids

Size Management for Overspill: Using grid-auto-rows, such as in grid-auto-rows: 9rem, determines the height of rows generated by implicit overflow.

Visualizing Grid Layout

Using Inspector Tools: Employ browser inspector tools to visualize and manage grid structures, providing clarity on column and row placements.

Positioning Within a Grid

Spanning Grid Lines: Techniques are available for positioning grid items to span multiple grid lines for enhanced layout flexibility.
