What is css filter property

CSS filter is a visual effects as in photoshop. In CSS filter have many type filter method as: none, blur(3px), brightness(), contrast(), drop-shadow(), grayscale(), hue-rotate(), invert(), opacity(), saturate(), sepia(), url(). All method can be use for the image effect. Some method we can not use for the text content.

 blur(px): blur effect you can apply an image or text content. blur effect has zero value in the default. when you want extra blur then increase your value.

 brightness(%): you can increase and decrease brightness of the image. It's valued starting from 0% to 100%. If you will fill value 0% then the image shows black and if you will use 100% then it will be showing original image brightness. If you want to show your original image then fill value 1. when required more brightness then need 100% ++ as like brightness(150%), brightness(220%) Or as you wish to fill and check.

 contrast(%): It's working as brightness values.

 drop-shadow(horizontal-shadow vertical-shadow blur spread color): You can apply shadow effect images or content. It's work as CSS box-shadow and text-shadow at text content. "spread" value not supported now at this time.

 grayscale(%): where we required black and white image then we use this effect.
