CSS Specificity Conflicts During Migration of Legacy Application to Modern Framework
I tried several approaches but none seem to work. I've searched everywhere and can't find a clear answer... Currently developing a migration plan for a legacy web application that heavily relies on inline styles. The client wants to integrate a modern framework like Vue.js, but I'm running into serious CSS specificity issues. Existing styles were directly applied within HTML elements, which leads to conflicts when introducing new CSS classes. To tackle this, I’ve tried using scoped CSS in Vue components but found that the inline styles still take precedence. Here’s a snippet from the problematic component: ```html <template> <div class="container"> <div class="header" style="color: red;"> Legacy Header </div> <div class="new-header"> New Header </div> </div> </template> <style scoped> .new-header { color: blue; } </style> ``` Despite my efforts, the color remains red due to the inline style. I attempted to override it by adding `!important` in the scoped style, but that feels more like a workaround than a proper solution. Additionally, integrating tools like PostCSS to handle CSS variables and using utility-first libraries like Tailwind CSS has complicated things further. Here’s how I tried to configure Tailwind: ```javascript module.exports = { purge: [], darkMode: false, // or 'media' or 'class' theme: { extend: {}, }, variants: { extend: {}, }, plugins: [], } ``` Still, the existing inline styles interfere with Tailwind's utility classes. Has anyone successfully navigated these types of CSS specificity issues during a similar migration? Any insights on best practices or strategies to ensure that the new styles take effect without disrupting the existing layout would be greatly appreciated. This is part of a larger application I'm building. I'd really appreciate any guidance on this. I'm working on a application that needs to handle this. What's the best practice here? How would you solve this?
