window.resizeTo( … )
See here:
- You can’t resize a window or tab that wasn’t created by window.open.
- You can’t resize a window or tab when it’s in a window with more than one tab.
- Also, even if you create window by window.open(…) it is not resizable by default …see 4.
- To make window created by window.open() resizable, you must open it with resizable feature
myExternalWindow = window.open("http://example.com", "myWindowName", "resizable");
myExternalWindow.resizeTo(500,500); //resize window to 500x500
What to do if you accidentally press Ctrl+S in Vim
If you press Ctrl+S in Vim (i.e. because that’s hard-wired for ‘save’) your terminal may lockup, depending on how it’s configured.

Everything is easy when you know how.

<input type="number" pattern="[\d\.]*" step="0.01" inputmode="numeric">
HTML glow effects
Found some cool glow effects. Couldn’t actually get them to work in my context, but it’s the thought that counts.
Passing selected value into HTML select onchange handler
So you have a <select> element and you want to call a handler, but you need to pass the selected value to the handler because you have multiple instances of the same <select> and can’t access them by ID (because there is many, one of which will have the new selected value, but you don’t know which). The solution is to pass in the newly selected value, like this:
<select onchange='handle_change( this.value )'>
Easy-peasy!
