Interesting to perhaps no one else but those others that have suffered with it, the PDF specification allows drawing rectangles and other in-line graphical elements inside a 'sort of' canvas from a bottom right co-ordinate space only. I wondered for a while why that was.

I still use tables for layouting because divs and messing with positioning/floating never really clicked for me.

Nothing wrong really. Tables used to sucks in IE era. But now IE is gone. Modern HTML Tables are fine as long as you know its limitations or basically dont try to do any fancy thing with it. For some strange reason I see people keep saying aviod table at all cost. I dont get it. May be someone could explain it better.

Tables are perfect for tabular data. They are the correct markup and should be used for that (so not avoided at all cost).

Tables are not the correct markup for positioning various items here and there to create a layout on a page.

I feel like canvas tag plus image maps work really well together

Terrible for accessibility though. I'm sure screen readers have come a long way, but the core issue we dealt with 15-20 years ago was that the convenience of an imap wasn't worth breaking accessibility standards.

With more of our traditional desktop services having moved to mobile and now moving back to the browser, I'm more concerned about this creating another wave of accessibility limitations caused by a petty convenience for dev.

I don't want to sound off like an activist, but I'd like to see that someone with limited mobility or sight can equitably access services they, as much as we, will sooner or later have to depend on as current apps and software lose support and phase out. The Net has always been a place where a person's only limitation should be their choice to not commit their time to learning how to use it. Let's stand by that now more than ever, or I fear we'll hand an uncontested victory to the idiots in Silicon Valley who want us to adapt to how they want us to use the Net.

> we'll be revisiting this opinion once responsive websites with their (gasp) automatically resizing images are out of fashion.

Will this ever happen? We won't stop having radically differently sized devices any time soon. Of course I'm sure eventually the "responsive" approach will give way to other techniques but I can't really see the high-level approach disappearing.

Do you mean the bottom left corner? That's what ReportLab (python PDF authoring package) uses. It kinda makes sense wrt the cartesian coordinate system where x coordinate increases to the right and the y coordinate increases upwards, thus the origin is at the bottom left. But yeah, from a UX perspective it's one of those cases where practicality would have been better than purity.

The author seems to be have written this post based on work for an in-browser video editor ( https://videoinu.com/editor ). It runs completely on the client-side, so all the editing, previewing, rendering, and exporting is done using web technologies. Of course, it's not comparable to a professional editing tools but nevertheless that's very impressive achievement in my opinion!

If so, why just not use native desktop/mobile video editor app instead?

They're x, y pairs for the top-left and bottom-right corners of the rectangle. They're coordinates in the fourth quadrant of the Cartesian plane (i.e., with the origin conceptually in the top-left corner), which is also the way coordinates are given in most windowing systems (including X). This is more obvious when using the "poly" attribute rather than "rect," where you can have an arbitrary number of x, y pairs (an…

something I always wondered since the age of programming mode 13h, is the use of the fourth quadrant so that loop would fill video memory in the order the scan line goes reading it?
