Is there any way to disable focus outline around the elements for all elements?

That blue highlighter that appears when ever we click or select some thing?

Thanks

The focus outline exists for accessibility. As such, it's not recommended to remove them entirely.

If using the all.css stylesheet, you can customize the --cds-focus color.

html {
  --cds-focus: #ccc;
}

If you must remove it, the easier way would be to set the color to be transparent.
