Blur your notes text while showing on video or a demo

While watching a video on youtube for obsidian and they not want to share some notes or copy-delete their base for sharing.

How about using CSS to blur some of the text, so you could open a note and only the links and titles show, or which things you like:

pre.CodeMirror-line span {
     color: transparent;
    text-shadow: 0 0 9px rgb(202 202 249 / 61%);

}

.markdown-preview-section li, 
.markdown-preview-section td, 
.markdown-preview-section p
{
     color: transparent;
    text-shadow: 0 0 9px rgb(202 202 249 / 61%);

}

Add these to your css. and vary colours or shadow for blur level.
