I need to show two values in my webpage for which i have made two gauges using d3. now both gauges point to different value but i am unable to show value along with the needle as using d3 functions is tricky for me. this is code which gives me two gauges

I have this error emessage No Firebase App '[DEFAULT]' has been created when I try to run the Flutter Web version, Chrome is blank after running the web app.

All my dependencies are uptodate. firebase_analytics: ^7.0.0 firebase_auth: ^1.0.0 firebase_storage: ^8.0.0 cloud_firestore: ^1.0.4

I added firebase.initializeApp()on Main.dart, I followed the guide No Firebase App '[DEFAULT]' has been created - call Firebase.initializeApp() in Flutter and Firebase

Firstly, i have minimum programming knowledge and just trying it to show something on my website. i need to show two gauges in my page where both will have different needle values. Now i was successful to find a code displaying a gauge in d3 where i was able to set the value. However when when i duplicate the div and the script to show two different gauges, both gauges are being rendered in second div even when i have kept ids for both divs and gauges different. here is my code

I got Uncaught (in promise) bad-precaching-response: bad-precaching-response :: [{"url":"https://myapp.vercel.app/_error","status":404}] with my next-pwa app and service worker doesn't work, when deploying my app in in vercel, though it works fine in localhost with no error. I followed basic usage in here https://www.npmjs.com/package/next-pwa, but I use firebase-messaging-sw.js to use cloud-messaging as well as sw.js(service worker) for pwa. Also currently I don't have _error.js, which is mentioned in the above error. I thought those things might influence the error but I have no clue so far. Actually I added _error.js to my project once but it didn't make any change... Can anyone help to solve this? Thank you in advance!

I would like to be able to change the style of R-Markdown-generated bullets in ioslides document-wide through the CSS file.

I understand that I can use HTML to change the format of unordered bulleted lists within the body of an ioslides file in R Markdown, as is discussed here to change the color. Doing this for every bulleted list seems kludgy.

I tried adding this to the CSS file:

I'm trying to build a multi-timezone clock that'll be displayed in a web browser in kiosk mode.

I've stolen the basic code from https://ampron.eu/article/use-case/digital-wall-clock-with-raspberry-pi/ and the kiosk setup from: https://pimylifeup.com/raspberry-pi-kiosk/ and modified it into: http://dotnetdotcom.net/tzclock.html but I can't figure out how to change the color of each of the timezones.

JavaScript isn't really anything I have any experience with, so if I'm doing it all wrong, please point me in the right direction.

Many thanks in advance!

Here's my code so far (87 lines):

I'm newbie in building PWAs and working with Workbox (V5). And I'm having problem making my page to be cached and work offline!

Here is what I have done:

1. I wrote my index.html file in a way that it has the needed meta tags for PWAs, loads the manifest file (manifest.webmanifest), and registers the service-worker JavaScript file (sw.js).
2. I installed workbox-cli using npm install workbox-cli --global command.
3. I generated my workbox-config.js file using workbox wizard command and tweaked it manually to fit my desire configurations.
4. I finally generated my service-worker (sw.js) file and a workbox-xxx.js file using workbox generateSW workbox-config.js command.

Now when I run my page on localhost and then open up the Chrome DevTools, and go to Lighthouse section to audit my webpage with it, it says my app is installable, and PWA optimized... But says it doesn't work offline:

There is some white space between header-main and main-footer. I would prefer to either color them as the rest of the website or remove them completely. Basically, I dont care about the space as long as it has the same color as the rest of the website #fefcf5.

Hope this edited version works better thank you

I'm using Ionic 5 here, and iIve noticed that when I have a number of items in a list in the slide on ion-slide 1, and a few in the next ion-slide, when I transition between the two programatically, the slide with fewer items in starts way below the actual content it holds.

It's like the slides share a Y scroll position during the transition.

The slides, two of them, populated with some ion-items ( and sliding items ) nested inside an ion-list, they are "swiped" by the interactions with the ion-segment-buttons.

Is there a way to either scroll to the top of the next slide rapidly so that it's not noticed during the transition, or, someother code voodoo I need to add to stop slide 2 from starting at the Y point that slide 1 transitions from..

edit: a github repo of the code in action, scroll to the bottom of the long list, then click Group2 and the next slide starts from the same Y point as the previous.
