CSS Custom Properties implementation guide in Vue.js Reactive Components with Scoped Styles
I'm working on a Vue.js application where I'm trying to use CSS custom properties (variables) to dynamically change styles based on user input... However, I'm working with an scenario where the custom properties defined in my scoped styles don't seem to update reactively when the state changes. For instance, I have the following setup: ```vue <template> <div class="color-box" :style="{ '--main-color': mainColor }"> <input type="color" v-model="mainColor" /> </div> </template> <script> export default { data() { return { mainColor: '#ff0000', // default color }; }, }; </script> <style scoped> .color-box { width: 100px; height: 100px; background-color: var(--main-color); } </style> ``` I expect that when the user selects a new color, the background color of the `div` should change accordingly, but it remains the same. I've also tried using inline styles directly on the `div` without scoped styles, but it still doesn't reflect the changes. The output console doesn't show any errors related to this. I've verified that `mainColor` updates correctly by logging it, so the scenario seems specific to how Vue handles CSS custom properties. Is there a way to ensure that the custom properties update correctly and reflect the changes in the component? I've checked the Vue.js documentation and searched through various forums, but I haven't found a solution that addresses this specific scenario. Could this be a known issue?
