Themalize provides consistent styles for typography, forms, buttons and tables designed with theme optimized light and dark mode color-schemes, and a variety of optional utilities and pre-styled components. Built with Sass and setup to enable importing over 70 different elements selectively when compiling, also includes compiled style sheets with the assets for editing as regular CSS.
See the website Themalize.com for a demonstration of all the elements included as styled, also includes HTML examples on usage and an overview of customizing the styles to suit specific project parameters.
