This is an example of simple signup with social media web form, designed using CSS, HTML, and Bootstrap framework 4. The social media images are imported to the code with their URLs. The users are given the ability to sign up by clicking on the images, which are displayed in two rows. The body of the form is given a background color of RGB(0, 0, 0), and font color of #fff. The card container is given a margin-top as 200px, whereas the title of the form is given a font-size as calc(16px + 6 * ((100vw - 320px) / 680)). The images are given the styles of width as 250px, height as 150px, and border-radius as 7px. The second row of images is given a margin-top style as calc(18px + 6 * ((100vw - 320px) / 680)). Media quarries are also used to increase the responsiveness of the form. Source:
