By differentiating your website, you can use items with different appearances, such as what we have prepared in this code. In this code we have a tab or menu. This tab or menu acts as a slide and an oval is placed on each item selected. This oval is blue and by placing it on each item, the title color also turns blue. Normally, before selecting any color item, their title is black.
