This page was created using the latest CSS capabilities in modern browsers – namely display:grid. If you look at the source you can see how the grid works. This gallery was created using a “Mondrian” style layout. Bootstrap was only used for the modal (pop-up) and panel (now the card class in Bootstrap). Also, note the use of columns for this section. Another way to make the reading flow work much better. There are a lot of training videos on how to use display:grid. Doc’s recommends viewing Jen Simmons labs and videos or search Jen Simmons on YouTube. She has done a great job working on the grid. This new capability allows designers a whole new way to design layouts, thus making the content stand-out with a better user experience.
