Oh boy.
We had a class in the first semester of uni where we had to create a static html page based on a screenshot.
There was this one textbox at the top of the site, where the only way you could recreate the screenshot was by using a <br/>
in the middle of the text.
The prof was very picky about your HTML being semantically thorough and correct, so that was super weird that that was necessary.
While he advocates for it, that’s also a point that Martin brings up multiple times when he talks about his project “fitnesse”.
Basically saying that they left it open how stuff can be saved, but the need has never arisen to actually pivot to a different system.
