Is there a way to style this link?

STEP 1: 
Add the following JavaScript code to the Footer using Code Injection.  This script adds an "active" class on the link that matches whatever filter is defined in the query parameter in the URL. 

(function () {
    // Get all the links inside the specified container
    const links = document.querySelectorAll("#block-yui_3_17_2_1_1705961330405_3743 a");

    // Get the query parameter from the URL
    const urlSearchParams = new URLSearchParams(window.location.search);
    const urlTag = urlSearchParams.get("tag");

    // Loop through each link and check if its query parameter matches the one in the URL
    links.forEach((link) => {
        const linkSearchParams = new URLSearchParams(link.href.split("?")[1] || "");
        const linkTag = linkSearchParams.get("tag");

        // Add the "active" class if the query parameters match
        if (linkTag === urlTag) {
            link.classList.add("active");
        }
    });
})();

Step 2:
You can now style the class like so using the following CSS:

/* Style active blog filter link */
#block-yui_3_17_2_1_1705961330405_3743 .active {
    color: blue;
}
