implementing Dynamic Theme Switching in Vue 3 - implementing CSS Variables
This might be a silly question, but I'm having trouble implementing a dynamic theme switcher in my Vue 3 application. My goal is to allow users to toggle between light and dark themes, but I'm running into issues with CSS variables not updating correctly on theme switch. Here's what I have so far: I've defined my CSS variables in a separate stylesheet like this: ```css :root { --bg-color: white; --text-color: black; } .dark-theme { --bg-color: black; --text-color: white; } ``` In my Vue component, I have a method to toggle the theme: ```javascript <template> <div :style="{ backgroundColor: bgColor, color: textColor }"> <h1>Hello World</h1> <button @click="toggleTheme">Toggle Theme</button> </div> </template> <script> export default { data() { return { isDarkTheme: false }; }, computed: { bgColor() { return getComputedStyle(document.documentElement).getPropertyValue('--bg-color'); }, textColor() { return getComputedStyle(document.documentElement).getPropertyValue('--text-color'); } }, methods: { toggleTheme() { this.isDarkTheme = !this.isDarkTheme; document.documentElement.classList.toggle('dark-theme', this.isDarkTheme); } } }; </script> ``` However, when I switch themes, the colors do not update as expected. Initially, it works, but if I toggle back and forth multiple times, the colors seem to get exploring on one theme or the other. I’ve also tried using `this.$forceUpdate()` after toggling the class, but that doesn't seem to solve the question. I'm using Vue 3.2.0 and have already cleared my browser cache to ensure there are no stale styles. The console doesn't throw any errors either. What could be causing the inconsistency? Any insights or suggestions would be greatly appreciated! Am I missing something obvious?
