Sample code for implementing exquisite personalized navigation bar somersault cloud effect using JavaScript
Achievement effect:
Implementation effect is shown in the figure below
##Implementation principle:
What is the somersault cloud effect: •This effect is very simple, that is, when the mouse is moved to other navigation directories, the background image will slide with the mouse to the current directory.Implementation ideas:
•When the mouse passes by, use offsetLeft to get the distance from the current box to the left, and assign this value to the end value of the easing animation.•When you click, remember the current offsetLeft value. When the mouse passes by, give the previously clicked offsetLeft the value when it passes now.
Implementation code:
The following is the implementation code and detailed comments. The core is to set a span tag with position absolute, bind the mouse event, and use the encapsulated animate Animation realizes span's "somersault cloud" effect.<!DOCTYPE html>
