  You could use CSS variables and a little bit of JavaScript to switch themes.
  Define the theming in the .light or the .dark then set the class of the body to it. It will set the variables to the theme color.
  Ex:
  function toLight() { document.body.classList.remove('dark'); document.body.classList.add('light');}function toDark() { document.body.classList.remove('light'); document.body.classList.add('dark');}
  
  .light { --font-color: #111; --bg-color: #fff;}.dark { --font-color: #eee; --bg-color: #111;}p, h1 { color: var(--font-color);}body { background-color: var(--bg-color);}
  
  <body class="light"> <h1>title</h1> <p>text blah blah</p> <button onclick="toDark()">switch to dark</button> <button onclick="toLight()">switch to light</button></body>

- How do I force Update my components in my react code to toggle dark theme to light theme
  Top Answer
  Answered Dec 25, 2020 · 4 votes
  Here is a working code:
  import React, { useState } from "react";import { ThemeProvider, CssBaseline } from "@material-ui/core";import darkTheme from "./Theme/darkTheme";import lightTheme from "./Theme/lightTheme";import PrimarySearchAppBar from "./Components/Appbar";import { createMuiTheme } from "@material-ui/core/styles";function App() { const [dark, setDark] = useState(true); const Theme = dark ? createMuiTheme(darkTheme) : createMuiTheme(lightTheme); return ( <ThemeProvider theme={Theme}> <CssBaseline /> <div> <PrimarySearchAppBar thm={dark} Togglethm={setDark} /> </div> </ThemeProvider> );}export default App;
  
  Please note the two lines that are different from your code:
  import { createMuiTheme } from "@material-ui/core/styles";......const Theme = dark ? createMuiTheme(darkTheme) : createMuiTheme(lightTheme);-
  
  It appears that for the themes to work MUI needs to create the theme (using createMuiTheme on every render). I do realize you're using createMuiTheme in your theme definitions (darkTheme.js and lightTheme.js), but those are superfluous. You can safely rewrite those files like so (which is what I did in my sandbox):
  const darkTheme = { palette: { type: "dark", primary: { main: "#00e676" }, secondary: { main: "#e6006f" } }};export default darkTheme;

  Am I doing it incorrectly?
  No, it looks correct.
  Although I would question the size of the numeric data types as you are restricted to only have 1999 teachers and 199 classes (including negative numbers); this may be enough for immediate use but after several years when classes get re-organised or when the syllabus is re-written and new classes are created then you may run out of primary keys.

- How do I set system preference dark mode in a react app but also allow users to toggle back and forth the current theme
  Top Answer
  Answered Apr 09, 2020 · 1 votes
  The problem is that the whole block of useLayoutEffect runs every the dark value changes. So when the user toggles dark, the prefers... if statements run and setDark back to the system preference.
  To solve this you'll need to keep track of the user manually toggling the theme and then preventing the prefers... if statements from running.
  In your ThemeProvider do the following:
  Add a state to monitor if the user has used toggle
  const [userPicked, setUserPicked] = useState(false);
  
  Update your toggle function:
  const toggle = () => { console.log('Toggle Method Called'); const body = document.getElementsByTagName('body')[0]; body.style.cssText = 'transition: background .5s ease'; setUserPick(true) // Add this line setDark(!dark);};
  
  Finally, update the useLayout to look like this:
  useLayoutEffect(() => { if (!userPicked) { // This will stop the system preferences from taking place if the user manually toggles the them if (prefersDark) { setDark(true); } if (prefersLight) { setDark(false); } if (prefersNotSet) { setDark(true); } } applyTheme();}, [dark]);
  
  Your toggle component shouldn't have to change.
  Update:
  Sal's answer is a great alternative. Mine points out the flaw in existing code and how to add to it. This points out how to which your code more effectively.
  export function ThemeProvider({ children }) { const prefersDark = window.matchMedia('(prefers-color-scheme: dark)').matches; const [dark, setDark] = useState(prefersDark); useLayoutEffect(() => { applyTheme(); }, [dark]); ...}

- How do I create a Django web application with an HTML/CSS/JS frontend and a Django and Flask backend?
  Top Answer
  Answered Nov 13, 2018 · 1 votes
  Just follow the instructions:
  virtualenv envsource env/bin/activatepip install -r requirements.txtFLASK_APP=app.py flask run
  
  You can do without a virtualenv but you're gonna need Python and pip installed. Assuming you got Python installed, you also need to be able to run pip so that you can install the dependencies. If you still cannot start Flask after doing that, you should check that the python scripts are in your system PATH variable.
  Then you just follow the Flask routing scheme and use Django as a backend for your weather service. The application logic is not that large.
