# CSS Snippet: Make the block section not full height for ACSS

Some users don't like the full window height block section when Automatic CSS is enabled. 

<figure><img src="/files/hSiXOJIw0L3vVH5eeEHr" alt=""><figcaption></figcaption></figure>

You can disable this by this CSS available in [Gutenberg Editor Custom CSS](/customizing-gutenberg/gutenberg-editor-custom-css.md)

Code:

```css
/* ACSS: Make the edtitor not full height */
body .is-root-container {
  min-block-size: unset !important;
}
body .editor-styles-wrapper.block-editor-writing-flow {
  min-block-size: unset !important;
}
```
