问题 I have an issue with max-width media rule. I test to hide the elements on different max-width values and the behavior is inconsistent. I have tested 4 scenarios varying in the screen width. Scenario 1 : Screen width is 638px: This matches my expectation. Scenario 2 : Screen width is 639px: This is wrong! I expect column639 still to be hidden! Scenario 3 : Screen width is 640px: This matches my expectation. Scenario 4 : Screen width is 641px: This matches my expectation. Question: What causes

问题 I'm currently developing my first webapp, frontend with React and backend with FastAPI . I'm trying to test it out jointly with Chrome-- see if the frontend makes the correct API calls to backend, and display the results. I've been having problems with cookies, and I'd like help. Apologies in advance for the long post – I've been going through many resources past couple of days, and at this point I'm unsure what's relevant and what's not. Frontend on localhost:8080 Backend on http://127.0.0.1

I've got a content script that does this function once the script has been done. chrome.runtime.sendMessage({complete: true}); I've got a background script that loops through every item in an array and uses one of its values to open a URL with chrome.tabs.update. What I'm trying to do is make the async function wait for the Message the content

问题 I launch a URL from another domain and then postMessage to it const child = window.open("http://urlfromanotherdomain.com"); child.postMessage("you cant handle the message", "*"); The JavaScript code, in the child window I launch, registers its interest as follows: window.onmessage = function(ev) {window.console.log(ev);} The problem is that sometimes there's so much code to run in the child window before it's able to register interest that it doesn't receive the posted message. How do I
