I'd like to add to Carl's suggestions. If you're looking for more variety, "HTML5 UP" (html5up.net) is a fantastic resource. They offer a collection of free, responsive HTML5 templates that can be used for portfolios. The templates are visually stunning, and they come with smooth animations and effects that can make your portfolio stand out. Another option you might consider is "Colorlib" (colorlib.com). They provide a wide range of free portfolio templates built with HTML and CSS. The templates are well-designed and easy to customize, even if you don't have much coding experience. Overall, these resources should give you a great starting point to find the perfect template for your portfolio.
