Bootstrap Sidebars:

Hidden Sidebar with Toggle Button Using Bootstrap

To differentiate your website from the others and make it stand out, you can utilize some special techniques and styles to make it more appealing. This does not just make your site look nicer. It actually affects the number of visitors your site can lure in because of how it looks. One of the styles that many sites owners use is sidebar. Sidebars are useful tools and let you hide user panels, categories, etc. on your webpages which the users can access easily.

In today’s post, we are sharing a Bootstrap blue sidebar with the ability to change your website’s appearance greatly. As with many other hidden sidebars, this one can also be opened or closed via a toggle button but unlike the simpler ones, this blue button is designed like a triangle which is much more interesting. This blue left sidebar has a purplish-blue background with light blue texts. In hover mode, the normally blue texts will turn white to indicate they are being selected. This beautiful sidebar truly has a unique and sleek design and can attract any user’s attention. You can use this left sidebar in your own website without paying any money by simply scrolling down.a
