Is it me or is the responsive design example not working for me?

[Leong-Qi-Jin]

For this example and a few others on this link (https://tailwindcss.com/docs/responsive-design#targeting-mobile-screens):
<div class="text-center sm:text-left"></div>

This doesn't work unless I add an 'important' to the media queries, i.e.:
<div class="text-center sm:text-left!"></div>

To avoid the important tag, I currently do the following as a workaround instead:
<div class="max-sm:text-center sm:text-left"></div>

Same goes with the other examples. Not sure if I am doing something wrong. I'm on Tailwind 4.1.10.

Consider providing a git repo that reproduces the issue and we can take a look for you.

Let me try and reproduce the issue. For some reason, it doesn't happen on my personal website, just on a project at work. I don't think it's related to the Tailwind version.

[Leong-Qi-Jin]

I can't seem to reproduce this issue reliably. Even in the same project and the same element, this issue doesn't pop up all the time.

I would literally swap between the following:
max-sm:text-center sm:text-right
max-sm:text-center text-right

And sometimes it would be permanently text-right and sometimes not. When inspecting element, the classes are correct though.

This behaviour occurs in all browsers I tested (on macOS), and affects all classes I tested, not just text-center/text-right.

It might be some hot reload or cache issue? Will investigate further

Could be you have multiple instances of Tailwind-compiled CSS on the webpage. Consider checking you only have one single instance. Otherwise, it could be incorrect integration/configuration.

[Leong-Qi-Jin]

Ah you're right, that is the problem. The project is a monorepo with a "consuming" package (apps/web) and a component library package (shared/react). After following your instructions in a separate post, everything seems to work properly now.

These are the changes I made in case someone in the future is interested:

apps/web/main.tsx

import './App.css';
-import '@shared/react/dist/style.css';

apps/web/App.css

+@import 'tailwindcss';
@import '../../../shared/react/src/css/index.css';
+@source '../../../shared/react/dist';

shared/react/index.ts

-import './src/css/index.css';

shared/react/src/css/index.css

-@import 'tailwindcss';
+@source "../../dist";

I have not fully tested this, but it seems to work. Though I'm not too sure how this will impact the Storybook that we will implement in the future.

Thanks @wongjn! You saved me a bunch of time (in this post and the other).
