1. CSS Backdrop Filter

    Method of applying filter effects (like blur, grayscale or hue) to content/elements below the target element.

  2. Crisp edges/pixelated images

    Scales images with an algorithm that preserves edges and contrast, without smoothing colors or introducing blur. This is intended for images such as pixel art. Official values that accomplish this for the `image-rendering` property are `crisp-edges` and `pixelated`.

  3. CSS filter() function

    This function filters a CSS input image with a set of filter functions (like blur, grayscale or hue)

  4. CSS Filter Effects

    Method of applying filter effects using the `filter` property to elements, matching filters available in SVG. Filter functions include blur, brightness, contrast, drop-shadow, grayscale, hue-rotate, invert, opacity, sepia and saturate.

  5. CSS3 Text-shadow

    Method of applying one or more shadow or blur effects to text

  6. focusin & focusout events

    The `focusin` and `focusout` events fire just before the element gains or loses focus, and they bubble. By contrast, the `focus` and `blur` events fire after the focus has shifted, and don't bubble.

  7. SVG filters

    Method of using Photoshop-like effects on SVG objects including blurring and color manipulation.
