::-webkit-search-results-button
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
The ::-webkit-search-results-button CSS pseudo-element represents a button (the "search results button") at the left edge of an <input> of type="search" which when clicked displays a menu which allows the user to choose from previous recent search queries. This button and pseudo-element are non-standard, supported only in WebKit and Blink, hence the vendor prefix. The search results button is only shown on search <input> elements that have a results attribute.
Syntax
