This time we will bring a 3D button based on CSS3, which has a retro style and font. The first button tilts to the left or right according to the position of the cursor when hovering, and its style is similar to that of an old game console. These buttons are configured with sm, md, lg size classes and bootstrap-esque classes, such as primary, secondary, dangerous, warning, success and info. The second button is a loader button, which will have its own progress bar when pressed. It only pushes towards the center, but then opens up, displaying a progress bar on its front. Depending on the success of the operation, it will display specific information when it is completed.
