SpoilerBlur is a short and minimalistic CSS code that softly blurs a specified sentence, word, range, or paragraph. If the visitor hovers over the text, the blur will fade away and the content will be displayed. If the visitor doesn't hover over the text, the content will keep its blur. If the visitor no longer wants to see the spoiler, they can move their cursor away from the text to blur it.
Installation
Usage
