In what cases can you set a fixed width when layout on flexbox? In what cases is it possible and impossible?

Question

Flexbox

I can't figure out the flashes a bit. If you can’t use block layout, then how to set the width or height for some blocks, or you can still use a fixed height and width for blocks that, for example, need to be put in a row, for example, there should be a photo, text from the bottom, and what would this block be specified width and height. So, in this case, it is possible to set a fixed height and width to the blocks? And is it possible to set margins and paddings?

Answer 1

You can always set fixed sizes and indents :)
