html – How to display an unordered list in two columns? – Stack Overflow

Posted by jpluimers on 2025/06/05

For a, I wanted to a HTML ul list the SQL keywords in multiple columns I was afraid this would be a tough CSS job, but in practice it was way easier than even explained in the below Stack Overflow answers that made me find

[Wayback/Archive] columns – CSS: Cascading Style Sheets | MDN

The columns [Wayback/Archive] CSS shorthand property sets the number of columns to use when drawing an element’s contents, as well as those columns’ widths.

TL;DR:

  • I used <ul style="columns:3">...</ul>
  • For setting column width, this failed in Chrome <ul style="column-count: 2; column-width: 15em;">...</ul>
    but this worked: <ul style="column-count: 2; width: 480px;">...</ul>

Here are the answers:

Yes, you can globally block JavaScript and enablpe per-site, but you block Bookmarklets too

Posted by jpluimers on 2025/05/16

Trying to trim down excessive CPU usage of my web browsers, and lessen the risk of intrusion, I experimented with globally disabling JavaScript and only enabling it on sites where it adds value to me.

That is possible (see below), but immediately showed a big side effect: Bookmarklets will not work on sites that have JavaScript disabled.

Disabling JavaScript globally only allows Bookmarklets on sites where you have enabled JavaScript. Not the situation I hoped for (:

I’ll try it for a while though.

I wonder how long this can be hosted on GitHub. Will start using it, just to learn more about the GitHub computing infrastructure.

A signal of the future WebAssembly/emscripten is giving us: a database served on a static web page

Posted by jpluimers on 2025/04/17

From a quite a while back; apparently it ended up in the drafts in stead of the blog queue:

[Wayback/Archive] Ian Miell on Twitter: “A signal of the future WebAssembly/emscripten is giving us: a database served on a static web page: … The possibilities are dizzying. Also, I’ve thought for a while that if I had to put money on it, SQLite will outlast every other database out there.”

The combination of Emscripten and WebAssembly is cool as it allows you to run C/C++ based code in most Web Browsers at near-native speed (though the standard is open and can just as easily outside that realm).

Some HTTP redirect checking sites compared

Posted by jpluimers on 2025/04/02

 

Every now and then I want to check how a URL redirect, for instance when checking out why a domain failed loading in browsers a while ago because of certificate problems:

The thing was that back then, the site officially did not have a security certificate, but somehow the provider had installed a self-signed one. Most web-browsers then auto-redirect from http to https. Luckily the archival sites can archive without redirecting:

When querying [Wayback/Archive] redirect check – Google Search, you get quite some results. These are the ones I use most in descending order of preference and why they are at that position:
