I feel like I missed a memo or something. Are fluid layouts and grid layouts the same thing? What is this baseline thing I keep hearing about? Is the baseline just like something you create to line up all the words and pictures? How is that any different than just floating/clearing and using percentage widths?
Is this just revised terminology?
fluid layouts and grid layouts are essentially css starting points – most css grids can be used with either fluid widths or fixed widths
