My website embeds perfectly as expected everywhere I’ve tried EXCEPT Discord, for some reason it refuses to embed no matter what I try and I cannot for the life of me figure out why, I’ve tried:
remaking my tags entirely,
Stripping my backend of all security,
completely rebuilding my backend,
allowing discord through every bit of security I have,
The only times it has embedded properly were when i tried hosting one of my html files on tiiny.host and on github pages, so it MUST be something in my backend, but the only things I could think of possibly causing it were CORS, CSP, and Helmet, but even removing all 3 of them entirely didn’t work, I am at a complete and utter loss

I am trying to make a simple quiz app in vanilla javascript. When a user clicks on the wrong option, I want to change the background color to red and the color of correct answer to lightGreen. After these two color changes, I don’t want to change the background color of two remaining options to red when a user clicks on them.

let userSignedIn = false; // Function to handle login form submission function handleLogin(event) { event.preventDefault(); // Prevent form submission // Get input values var email = document.getElementById(“login-email”).value; var password = document.getElementById(“login-password”).value; // Retrieve user data from local storage var storedUserData = JSON.parse(localStorage.getItem(‘userData’)); // Login page confirmation if (storedUserData && storedUserData.email === email && storedUserData.password === […]

I’m currently developing a web application where users can access certain links after a countdown timer expires. During this waiting period, I’d like to display Yllix ads to make the experience more engaging & to make some $$. However, I’ve encountered a challenge in optimizing the performance of loading my web pages because these ads load even if they are hidden {display:none;} giving a laggy bad experience impression to my users. What i want exactly is loading these ads only if the countdown timer is triggered, otherwise it shouldn’t be loaded in background. Well i asked ChatGPT and Copilot both of them gave me dynamic executing solution but all of these methods not excuting the internal documents of the Ad Units i think because the yllix Ad units only load if they are place in pure html.
My attempt to dynamically append the Yllix ads without success indicates a potential limitation with Yllix’s implementation. Is there a workaround or alternative approach to achieve this? I’m open to any suggestions or insights on how to seamlessly integrate Yllix ads into my countdown timer functionality. And just a Note: i can’t use Adsens please don’t ask me to switch to other Ad Networks. Thank you in advance for your help.

I am designing a web app and the below code is supposed to find the most common HTML tag in a page’s source code, but it always returns ‘html’ instead of the correct tag. Why doesn’t this work as expected?

I have my javascript code but when I go onto my website, using the html, css and javascript the upload button, wont work in the file part for my website witch for my website I really need the proper javascript code, to make the upload button work so I can upload files or folders into the file part.
