Things such as radio buttons, sliders, and checkboxes are available both on the mobile and desktop, but some are easier to use on mobiles than others. In general, web browsers draw all of these elements slightly too small for comfort on most mobile devices. Where possible (for instance, select drop-downs), make individual form elements stretch the entire device width on mobiles, or in the case of things such as checkboxes and radio buttons, use the for property of the <label> element to make labels tapable, and scale these horizontally.
