前言

之前有人反映我的站点特别卡
也不是没有去优化。。。。。但是依然有人说很卡
我感觉是加载动画的问题,刚好我之前找到html+css实现彩虹猫
于是我给这个抄下来了
不废话,正片开始!

教程开始!

新建js

首先,新建[Blogroot]\themes\butterfly\source\js\nyan.js,内容如下:

function cycleFrames (_nyanCat, _currentFrame) {
_nyanCat.classList = []
_nyanCat.classList.add(`frame${_currentFrame}`)
}

function replicateSparks (_sparksRow) {
const numberOfRowsToCoverEntireScreen = Math.ceil(document.getElementById("loading-box").offsetHeight / _sparksRow.offsetHeight)
const newSparksRows = document.createElement('div')

for (let a = 0; a < numberOfRowsToCoverEntireScreen-1; a++) {
newSparksRows.append(_sparksRow.cloneNode(true))
}

document.getElementById("loading-box").prepend(newSparksRows)
}

(function () {
let nyanCat = document.getElementById('nyan-cat')
let currentFrame = 1

replicateSparks(document.getElementsByClassName('sparks-combo')[0])

setInterval(function () {
currentFrame = (currentFrame % 6) + 1
cycleFrames(nyanCat, currentFrame)
}, 70)
})()

这个是用来自动生成div,使得星星可以铺满屏幕

选择方案

以下三种方案任意选择一种:

店长魔改方案

最后修改_config.butterfly.ymlpreloader选项, 改完以后source: 1为满屏加载无pace胶囊,source: 2为pace胶囊无满屏动画, source: 3是两者都启用。(这边懒得说就搬运的鱼佬那加载动画的教程了。。。。。反正都一样。。。。。)
