# Cleanup Whitespace and duplicate classnames in Tailwind using Prettier

Tailwind has released a new version of **prettier-plugin-tailwindcss** which adds support for removing unecessary whitespaces and duplicate classnames.

### Cleaningup unecessary whitespace

When you are copying a classname or deleting a class name from the middle of a list, it's easy to endup with some extraspace that needs to be cleanedup.

Now prettier plugin will handle it automatically.

### Removing Duplicate Classes

VS Code will warn us if we use the duplicate classnames using the yellow lines, but now Prettier plugin can remove those duplicate classes automatically.
