Title: Update _clearing.scss

When creating a clearing gallery using block-grid for presentation, some styles interfere with the presentation of clearing.
Example:
```html

```
The style for the block-grid break the presentation of the clearing thumbnails with this selector .large-block-grid-4 > li:nth-of-type(4n+1) because the fith thumbnail will be cleared and floated to the left.
