"Perfection is achieved not when there is nothing more to add, but nothing left to take away."

I value negative space in the same way that my dream is not to pile my plate with as much as I can at a buffet.

That's nice, but I value text that renders at a legible size more than I value leaving the majority of my screen empty. This layout isn't effectively using negative space, it's just wasting the entire screen. At least on mobile.

On mobile I just use two thumbs to zoom in to the column I want to read.

If only we had simple CSS rules to present things in a way that doesn't require one to do this

Blatant ableism against the mono-thumbed or thumbless.

The mono-thumbed can always double-tap the desired column, and thumbless folx can use their nose.

How did you do that?

Unicode tricks. A quick Google search for "small text generator" will point you in the right direction.

You're free to call that "negative space", it's still 70% of my screen that's just blinding white, and 30% that's a tiny, non-responsive column layout. You call it perfect, I call it annoyingly empty and bad usability on mobile.

If you are looking for Pegasus mail on a mobile device, I think you might be a wee bit outside of the target market. And btw, Pegasus is a shareware site from the 1990s.

Why do you make the assumption that people running, or interested in running Pegasus, would not read things on their phone?

A lot of sites from https://512kb.club/ are like that.

Why does it need to take up more than 30% of your screen? And what's wrong with your phone? It works perfectly fine on mine.

Legibility and usability. Like many old sites this one uses small fonts, small elements, and has tiny targets. Especially when working on a large display. I make liberal use of Firefox's zoom feature to compensate, but better defaults don't hurt.

And yes it works on a phone as you can easily zoom in, but inclusion of responsive design, e.g. moving the sidebar to a footer, and use larger fonts would significantly improve legibility and usability. This is not incompatible with a simple and fast-loading site.

I guess we have very different definitions of "works perfectly". Sure, the page displays as intended, if that's what you mean. Tiny 3 pixel high links are neither accessible nor very usable.
