Common CSS Selectors Reference

CSS Attribute Name Description
border-radius Border Radius Most popular CSS property, it was the CSS3 flagship property. Changes the corners of a border to be more rounded. Setting the border-radius to half the width (or height) of a square, turns it into a circle.
box-shadow Box Shadow Applies depth to elements by adding a shadow. You can apply multiple shadows to the same element resulting in interesting effects.
text-shadow Text Shadow Similar to box-shadow but applied to text. It uses the same parameters too: x-offset, y-offset, blur, color.
text-stroke Text Stroke Essentially, it changes the outline of the text characters. If you have large uppercase text, you could outline it in one color, while it's filled in with another.
background Multiple Backgrounds The background property allows for multiple backgrounds. You could use an image and then overlay it with a semi-opaque texture changing how the image appears.
