Applying Tailwind CSS Styles Consistently Across Wireframe and Live React Website

Hi I created a wireframe and exported it with React but don’t see the same styling applied on my live react website as on the Relume.

If I had to guess the issue is with the tailwind css.
Also I would love to know any tips on how I can improve and use the styling with the style guide
