Grid Layout with Span Notation DemoJen demonstrates how to quickly complete the Mondrian painting demo by using a line-based grid layout with span notation. Using span notation will allow for the same grid layout while requiring less total code.
Grid System with CSS GridJen walks-through how to create a Grid version of the desktop only layout used in the previous Flexbox grid system example. Using Grid to create this layout does not require any math and is less code to write overall. A student's question regarding what the value of the gap property represents is also covered in this segment.
Responsive Grid with CSS GridJen live codes a responsive Grid by adding media queries, new classes with an order property, and new classes with a grid-column property. New classes may overlap with old classes in order to override stylings.
Figure & Figure Caption with CSS GridJen demonstrates how to use Grid's ability to overlap cells to quickly overlay a figure caption on top of a figure. Using Grid to overlay figure captions avoids having to use absolute and relative positioning, however, the two elements being overlaid with Grid must be siblings. A student's question regarding why three rows were used instead of two is also covered in this segment.
Combining Grid Cells & AnimationJen walks-through how to alternate between overlapped images with grid, CSS animation properties, and keyframes. The keyframes percentage values represent the percent of time passed in the animation duration.
