Problems that may occur during the deployment of web applications can often present challenges for many developers. One of the common issues you might encounter is the non-functionality of the correct CSS after deployment. If you are using Tailwind CSS and experiencing this problem on Vercel, don’t worry; here are some helpful points to resolve it.
First, ensure that all configurations of your build files are correctly performed. This includes the tailwind.config.js file and any other files that may be involved in your project. Check to see if there is something in these files related to build paths that may have been incorrectly entered.
The next step is to verify the specific tags that are being used for building with Tailwind CSS; ensure there are no issues with npm scripts or specific commands in this context that could be causing problems. Ensure that relevant scripts such as build and postinstall are correctly defined.
Another common reason for this issue may be related to caching in Vercel. Make sure that the cache is cleared or disabled to allow the new changes to take effect correctly.
Additionally, optimizations performed for the production environment, such as tree-shaking and reducing CSS size, can sometimes remove certain necessary styles. Make sure these sections are correctly configured so that all required styles are preserved during the build process.
