You cannot do scripts or hrefs inside of general html components (from what know). You can use javascript or jQuery to add it. I believe this should work for you. Put this inside the javascript tab on the page. Change the component id (just hover over the info button of that particular component on the page builder page to get the id). Change the class to the class you want to wrap the link around (in this case blog-card). Change the link after href to the link you want to go to.
