CSS view transitions crashed my webpage

 My 'view transitions' were causing my game to crash in Chrome.


I got the 'Aw Shucks' message from Chrome.


I thought maybe the 'view transitions' needed a lot of memory to prepare the new page state in the background. I had just added lots of SVG's to my game which may use up memory. But Chrome's tools showed the 'view transitions' only used a modest amount of memory compared to holding the total page size.


It seems 'view transitions' are supported by most browsers now and are no longer experimental.


I get the same 'Aw Shucks' message when I run my large game through the online JSHint on an old PC.


I had a 'view-transition-name' on the 'root' element. I moved the name to smaller areas of the page that are actually displayed when the transition runs.  Chrome now crashed much less often.


I removed the 'view transition' animation from the start of the game because the page changes a lot. This seemed to have stopped Chrome crashing.


I was going to add an old-style CSS animation to the start of the game as a fallback. But there would be a pause between animating out the old page and animating in the new layout as the page is changed.


I also planned to move the SVG's from the HTML 'body' to data URL's in 'background images' in the CSS. I hoped this would remove all the elements within the SVG's from the document model


But, a few months later, I noticed Chrome no longer crashes when the 'view transitions' at the start of the game run. Maybe the Chrome developers improved the code. Maybe the problem was where two 'view transitions' ran at the same time

Minifying CSS

Image
Over half of my game is CSS. This is after the game is minified. Only a third of my game is Javascript when minified. It is hard to shorten the names of properties in the CSS rules. I also have lots of icons made using CSS. I would like to convert several individual CSS properties to 'shorthand' properties like 'animation'. Some of the CSS minifiers do something like this. But, I have empty CSS rules within which I set styles using JavaScript. The minifiers would remove these empty rules, by default. I also rely on some CSS rules being at the start and in a particular order so I can change the styles easily with JavaScript. Because of this, I only use the CSS minifiers on parts of my CSS. This can be a bit hard to manager. I decided to remove most CSS properties with vendor prefixes when 'minimising' my game. I use a 'sed' script to do this. The CSS minifiers do not shorten id and class names. In my other web pages, I used to have a list of names that I ...

Violating Flickr's terms of service

Image
 Flickr said I had violated their terms of service by having non-photographic content. Another user had reported this. I had not been using my Flickr account much so I experimented by adding images with captions containing tips and news.  The images were drawings from 'openclipart.org'. I also made a gallery of screenshots of my game. I removed these images. I left some graphs showing probability distributions of getting a 'line' or 'house' in bingo. I had no more trouble for a few months. But now, I cannot login. Flickr says my username is not valid. If I use a link to my images, then I get a a '410' HTTP code meaning the content was intentionally removed. Yahoo! acquired Flickr in 2005. Yahoo! let you store lots of images, and even videos. In 2018, Yahoo! (now owned by Verizon) sold Flickr to SmugMug. Now Flickr tries to be a community of photographers. I still have all the same images on Pinterest together with the captions Pinterest only allows short...

How a CSS fish animation works

Image
 I have been adapting an animation of fish circling as in a bowl with bubbles rising in the middle. The original is by Yusuke Nakaya. See:      'codepen.io/YusukeNakaya/pen/WNopRwX' The fish are made of CSS triangles:     .pfshFish-body .pfshScale {         width: 0;         height: 0;         border-width: 0 0 3.125em 6.25em;     @keyframes fishColor {       0% {         border-color: transparent transparent #6C99C6 transparent; The triangles are reflected around the 'x' and 'y' axes to make one side of the body of the fish:     .pfshFish-body .pfshScale.-pfshTop.-pfshFront {         transform: scale(1, 1) skewX(4.5deg) rotateY(-11deg) rotateX(23deg)                    translate(0.09375em, 0.15625em);     }     .pfshFish-body .pfshScale.-pfshTop.-pfshBack...
