Bug where content will not overflow

 I have had a bug twice where content will not overflow outside its container. I forget that I had set 'contain: content' in the CSS.


'contain' in CSS isolates a part of the HTML allowing the browser to speed up the rendering partly by stopping content overflowing into other areas. .


I was changing the color of each letter of the text with Javascript. I wanted to separate this from the large main content of the page which did not change. So I added 'contain'. It made a small diference.

Dark mode using 'invert' does not work on Firefox

 Implementing 'dark mode' with 'invert' on the 'html' tag does not seem to work on the old Firefox used in my local libraries. This version of Firefox does not invert the background. This Firefox just inverts the elements you add. The Firefox developers feel they are following the specification. Using 'invert' when there is an 'overlay' scrollbar on Chrome sometimes makes the scrollbar disappear. I am using the last version of Chrome on Windows7. I understand 'overlay' scrollbars have been removed from the latest versions of Chrome. Of course, a dark scrollbar on a black background does not make sense. So I would need to use 'color-scheme' to change the color of the scrollbar. But 'invert' does not work well with 'color-scheme'. I could not set the colour of this 'overlay' scrollbar with properties like '-webkit-scrollbar-thumb'.  So I am going to have to implement 'dark mode' by setting the...
