Based on my understanding of your inquiry so far, it seems like you are interested in styling anchor tags that lead to search results. Anchor links can be customized using various CSS properties such as color, font-family, and background. Furthermore, the appearance of links can vary based on their state.
The four different states of a link are as follows:
a:link - represents a normal, unvisited link
a:visited - signifies a link that has been visited by the user
a:hover - defines how a link appears when hovered over
a:active - indicates a link at the moment it is clicked
You have the flexibility to modify the background color of a link by directly styling the anchor tag in your external or inline CSS file. Alternatively, this can also be achieved effortlessly through JavaScript or jQuery styling properties. Experiment with the example below to observe if this aligns with your desired link behavior.
a:link {color:#FF0000;} /* styles for unvisited link*/
a:visited {color:#000000;} /* styles for visited link */
a:hover {color:#FF00FF;} /* styles for mouseover link */
a:active {color:#0000FF;} /* styles for selected link */
It's crucial to maintain the correct order while processing these instructions.
