Matsumoto Rangiku for G8F

Ah, I believe the plugin requires that the code is wrapped with <script> tags so that the DOM parses it as javascript. I also added an event listener so it loads after the content has been loaded just to be sure.

Updated code with script tags:

<script>
    document.addEventListener("DOMContentLoaded", (event) => {
        let postItems = document.querySelectorAll('.post-item');
        let contentWrapper = document.querySelectorAll('.the_content_wrapper');


        // Make thumbnails clickable
        postItems.forEach(element => {
            let originalLink = element.querySelector('.entry-title a');


            if (originalLink instanceof HTMLAnchorElement !== true) {
                return;
            }


            let newLink = document.createElement('a');


            newLink.href = originalLink.href;


            // Make the link span across the whole thumbnail
            newLink.style.position = 'absolute';
            newLink.style.top = '0';
            newLink.style.left = '0';
            newLink.style.right = '0';
            newLink.style.bottom = '0';
            newLink.style.zIndex = '999';


            // Add a slightly white background on hover
            newLink.onmouseenter = function() {
                this.style.background = 'rgba(255,255,255,.2)';
            };
            newLink.onmouseleave = function() {
                this.style.background = 'unset';
            };


            element.appendChild(newLink);


            // Remove title text rising on hover
            let title = element.querySelector('.post-desc-wrapper');


            if (title instanceof HTMLDivElement !== true) {
                return;
            }


            title.style.transform = 'unset';
        });


        // Replace links on product page with actual links
        contentWrapper.forEach(element => {
            let allStrong = element.querySelectorAll('strong');


            allStrong.forEach(strong => {
                if (strong.innerHTML.indexOf('https://') !== -1) {


                    // Quick fix to remove extra 'h' if there is a misspelled link
                    if (strong.innerHTML.startsWith('hh')) {
                        strong.innerHTML = strong.innerHTML.substring(1);
                    }


                    let link = document.createElement('a');
                    link.href = strong.innerHTML;
                    link.textContent = strong.innerHTML;


                    strong.innerHTML = '';
                    strong.appendChild(link);
                }
            });
        }); 
    });
</script>
