This article is about how to use cross-fade () to achieve translucency of background images in CSS. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The cross-fade () function allows two images to be mixed translucently. For example

HTML

Css

.box {

Width: 600px

Height: 450px

Background-image:-webkit-cross-fade (url (girl.jpg), url (1.jpg), 50%)

Background-image: cross-fade (url (girl.jpg), url (1.jpg), 50%)

}

Attention, friends, at present, Google needs to add a prefix-webkit- to support this function.

Let's take a look at the specific implementation:

The cross-fade () function takes a list of images and defines, as a percentage, the opacity retained when each image is mixed with other images. The percentage value must be encoded without quotation marks, must contain the "%" symbol, and its value must be between 0% and 100%. The percentage is treated as the opacity value of each image, which means that a value of 0% means that the image is completely transparent, while a value of 100% makes the image completely opaque.

The following format is to mix the 1.png image with 75% transparency and the 2.png image with 25% transparency.

Cross-fade (url (1.png) 75%, url (2.png) 25%)

The above form can also be written as

Cross-fade (url (1.png) 75%, url (2.png))

If no percentage is declared, both images will be 50% opaque, and the fade-in rendering is an even merge of the two images. The following is the same effect.

Cross-fade (url (1.png) 50%, url (2.png) 50%)

Cross-fade (url (1.png), url (2.png))

If no percentage is declared and contains three images, the opacity of each image is 33.33%. The following is the same effect.

Cross-fade (url (1.png), url (2.png), url (3.png))

Cross-fade (url (1.png) 33.33%, url (2.png) 33.33%, url (3.png) 33.33%)
