Related issue [Support cosmetic filters with explicit style properties](https://github.com/gorhill/uBlock/issues/781) and [example](https://github.com/uBlockOrigin/uAssets/issues/71#issuecomment-229503444) where it's useful.
It's exactly the same syntax of plain cosmetic filters (i.e. must be a valid CSS selector), except that the `:style(...)` suffix is appended at the end. The content in the parentheses must be one or more [CSS property declarations](https://developer.mozilla.org/en-US/docs/Web/CSS/Syntax) (separated by the standard `;`). It is not allowed to use property values with `url(...)`, such `style`-based cosmetic filters will be discarded.
It's exactly the same syntax of plain cosmetic filters (i.e. must be a valid CSS selector), except that the `:style(...)` suffix is appended at the end. The content in the parentheses must be one or more [CSS property declarations](https://developer.mozilla.org/en-US/docs/Web/CSS/Syntax) (separated by the standard `;`). It is not allowed to use
- property values with `url(...)`,
- backslashes (`\`-escaped values),
- comments (`/*`, `*/`)
such `style`-based cosmetic filters will be discarded.
As with the other new cosmetic filtering selectors, the `:style` can be used only for _specific_ cosmetic filters, i.e. there must be a hostname or entity specified for the filter.
