I made several significant changes to this site as web design enhancements, content editor, and the addition of new functionalities. These updates included creating a redirect from the secondary site alpin57lux.com to the online store, implementing filters for approximately 100 products, modifying the CSS/HTML of the theme to improve element display, and resolving various errors on the site, such as fixing the popup-close functionality. Additionally, I added an employment form, implemented a zoom-in feature for the product slider, and addressed numerous other improvements and fixes.
