Do you have any recommendations for good collection packages that can replace QueryList?

A few days ago, I was maintaining an old website of my own. I saw that there were many packages in the extension library that I didn't recognize, and I didn't remember installing them. Use composer remove to remove them one by one, and some prompts that they are not installed. Finally, I finally found out that it was caused by the installation of QueryList. Take a screenshot to commemorate this. This is the accompanying package that I removed when I removed QueryList. Really all I need is a sapling, but you give me the feeling of a forest. The website has been running for more than a year, and collection is only a small part of it. I just read articles that I think are good and then collect them with one click.

Happy holidays to all programmers of php Chinese website!

Early this morning, the 1024 Programmer’s Day flooded the circle of friends. Although there is no holiday and you may have to work overtime, it does not affect the festive atmosphere at all.

Caring family members sent 512 holiday red envelopes; considerate female colleagues put on plaid skirts. Looking around, there is a lively scene. Speaking of which, do you know why 1024 becomes Programmers’ Day? The reason I can think of is that 1024 is the most common code that programmers receive.

I followed some tutorials to create a CSS based floating scroll to top button. However, I noticed that there is extra white space below the last HTML element (e.g. the last line). The height of the extra white space matches my button height (50px). I also tried adding an extra div tag to enclose the arrowUpdiv tag and the gap was reduced, but there is still some small but noticeable empty space. I was wondering if there is a way to avoid the extra white space? #arrowUp{position:sticky;width:

Scramble HTML elements before the browser attempts to render them. Is this a rare valid use case for "document.write"?

I have a header area on my webpage that has some background images that loop through it. They are a bit high resolution and are above the fold so I don't want the browser to start loading any images other than the first one. But I also want to randomize the order of the images. The problem is that I'm using a static web host (Netlify). Some approaches I've considered: Put the elements into the document as usual, then use Javascript to query them and randomize their order. I'm reluctant because I think the browser has started loading the first image that arrives in the HTML and then it gets randomly

Ways to fix issue 2003 (HY000): Unable to connect to MySQL server 'db_mysql:3306' (111)

I recently tried to containerize my FastAPIPython server (also for replication/doubling purposes). Before, I had just a MySQL server in a Docker container and everything was fine, but when I also made my web server a service, it couldn't connect to the MySQL server, so now the application doesn't work. Below is the code snippet of the server database initialization connector in the application fromfastapiimportFastAPIimportmysql.connectorapp
