Web Design: Fixed-Layout, Flowed-Layout, Responsive Design
Note that in 2000s, there is big brouhaha among “web design” circles about Fixed-Layout vs Flowed-Layout. Most sites is fixed layout. best example is Apple. They assume ur screen is ≥ 1000 pixels wide. Fixed layout is like printed magazine. if ur window is smaller, u can only see parts.
see Web Design: Fixed-Layout vs Flowed-Layout
here's minimal window width assumptions of apple facebook google microsoft amazon etc sites around 2010 see Web Design, Minimal Window Width
the debate about fixed vs flowed layout is that, fixed is always better looking on a specific screen. But flowed looks much better on a screen not the designer intended/expected.
I prefer flowed, and thought about it for years. Flow layout is supposed to work in any screen size and ratio. In practice, its just impossible. What actually happens, as with today's “responsive design”, is just design for four or so intended screen size and ratio.
note that, web design began in ~1994 when html began. Around that time, most monitor is 640x480. around ~2005 it's 800px width. 2010 it's 1020 width (by now, laptops is most common). most professional web sites use fixed layout. i.e. design for specific screen width.
also, flowed layout is pretty much favored by nerds or programers, who focus on logical structure. example: chapters, sections, subsections. Fixed layout design, is favored by artists or “designers” (aka desktop publishing of 1990s on Mac), because it's pretty.
note, CSS was invented in 1996 but isn't used widely till ~2002. The thinking about flowed vs fixed layout was that, always markup by logical structure, but use css to make the design/layout. this is actually a myth to this day.
Other than academic papers, vast majority of commercial sites do not have any natural logical structure. The “logical” markup is just a artificial pretense. This can be seen today especially with so-called “single page app”. #css #design

cap. i thought it'd solve the font size problem. But very disappointed. It's a CSS length value. Not a property. We need a property, example:
