Butterfly 主题自带的 Loading 效果（两个嵌套矩形旋转盒子）略显单调并且不炫酷，今天手动添加几款比较自然好看的加载动画。
本教程参考了文末两位博主，特点在于：
可以根据配置项内的指定选项加载对应样式。
不选的样式不加载，有效节省资源。
优化了代码结构，方便读者融会贯通以后，自行添加其他加载动画。
内容支持自定义图片（png,jpg,gif均可）作为加载动画
OK，话不多说，魔改开始！
一、修改loading.pug 修改[Blogroot]\themes\butterfly\layout\includes\loading\loading.pug，下面代码中提供了多种款式，算上默认的旋转盒子加载动画，一共有7种，读者可以根据代码结构自行改写移除不需要的内容。
修改前(主题默认旋转盒子)：
1 2 3 4 5 6 7 8 9 #loading-box .loading-left-bg .loading-right-bg .spinner-box .configure-border-1 .configure-core .configure-border-2 .configure-core .loading-word= _p('loading')
魔改后：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 if theme.preloader.enable case theme.preloader.load_style when 'gear' include ./load_style/gear.pug when 'ironheart' include ./load_style/ironheart.pug when 'scarecrow' include ./load_style/scarecrow.pug when 'triangles' include ./load_style/triangles.pug when 'wizard' include ./load_style/wizard.pug when 'image' include ./load_style/image.pug default include ./load_style/default.pug
此处第一行的if用于判断preloader功能是否打开。下面的case和when则是根据配置项的内容加载指定的页面元素。default表示默认使用butterfly自带的旋转盒子动画。
二、创建动画结构模板文件夹 新建动画结构模板存放的文件夹，如无特别提示，所有动画模板均存放在[Blogroot]\themes\butterfly\layout\includes\loading\load_style\目录下。
1. default 新建[Blogroot]\themes\butterfly\layout\includes\loading\load_style\default.pug
这是之前默认的旋转盒子动画。
1 2 3 4 5 6 7 8 9 #loading-box .loading-left-bg .loading-right-bg .spinner-box .configure-border-1 .configure-core .configure-border-2 .configure-core .loading-word= _p('loading')
2. gear 新建[Blogroot]\themes\butterfly\layout\includes\loading\load_style\gear.pug
这是旋转齿轮加载动画。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 #loading-box .gear-loader .gear-loader_overlay .gear-loader_cogs .gear-loader_cogs__top .gear-top_part .gear-top_part .gear-top_part .gear-top_hole .gear-loader_cogs__left .gear-left_part .gear-left_part .gear-left_part .gear-left_hole .gear-loader_cogs__bottom .gear-bottom_part .gear-bottom_part .gear-bottom_part .gear-bottom_hole
3. image 新建[Blogroot]\themes\butterfly\layout\includes\loading\load_style\image.pug
这是自定义图片加载动画，所以没有预览样式。
1 2 3 4 5 - var loadimage = theme.preloader.load_image ? theme.preloader.load_image : theme.error_img.post_page #loading-box .loading-left-bg .loading-right-bg img.load-image(src=url_for(loadimage) alt='')
4. ironheart 新建[Blogroot]\themes\butterfly\layout\includes\loading\load_style\ironheart.pug
这是钢铁之心加载动画。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 #loading-box .loading-left-bg .loading-right-bg .iron-container.iron-circle .iron-box1.iron-circle.iron-center .iron-box2.iron-circle.iron-center .iron-box3.iron-circle.iron-center .iron-box4.iron-circle.iron-center .iron-box5.iron-circle.iron-center .iron-box6.iron-circle .iron-coil(style='--i: 0') .iron-coil(style='--i: 1') .iron-coil(style='--i: 2') .iron-coil(style='--i: 3') .iron-coil(style='--i: 4') .iron-coil(style='--i: 5') .iron-coil(style='--i: 6') .iron-coil(style='--i: 7')
5. scarecrow 新建[Blogroot]\themes\butterfly\layout\includes\loading\load_style\scarecrow.pug
这是哈尔的移动城堡里的稻草人动画。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 #loading-box .loading-left-bg .loading-right-bg .scarecrow .scarecrow__hat .scarecrow__ribbon .scarecrow__head .scarecrow__eye .scarecrow__eye .scarecrow__mouth .scarecrow__pipe .scarecrow__body .scarecrow__glove.scarecrow__glove--l .scarecrow__sleeve.scarecrow__sleeve--l .scarecrow__bow .scarecrow__shirt .scarecrow__coat .scarecrow__waistcoat .scarecrow__sleeve.scarecrow__sleeve--r .scarecrow__glove.scarecrow__glove--r .scarecrow__coattails .scarecrow__pants .scarecrow__arms .scarecrow__leg
6. triangles 新建[Blogroot]\themes\butterfly\layout\includes\loading\load_style\triangles.pug
这是旋转三角加载动画。
1 2 3 4 5 6 7 8 9 10 11 #loading-box .triangles-wrap .triangles-eiz .triangles-seiz .triangles-sei .triangles-fei .triangles-feir .triangles-trei .triangles-dvai .triangles-ein .triangles-zero
7. wizard 新建[Blogroot]\themes\butterfly\layout\includes\loading\load_style\wizard.pug
这是巫师施法加载动画。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 #loading-box .loading-left-bg .loading-right-bg .wizard-scene .wizard-objects .wizard-square .wizard-circle .wizard-triangle .wizard .wizard-body .wizard-right-arm .wizard-right-hand .wizard-left-arm .wizard-left-hand .wizard-head .wizard-beard .wizard-face .wizard-adds .wizard-hat .wizard-hat-of-the-hat .wizard-four-point-star.--first .wizard-four-point-star.--second .wizard-four-point-star.--third
三、修改loading.styl 修改[Blogroot]\themes\butterfly\source\css\_layout\loading.styl
修改前（默认旋转盒子动画的样式）：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 if hexo-config('preloader' ) .loading-bg position : fixed z-index : 1000 width : 50% height : 100% background-color : var(--preloader-bg) #loading-box .loading-left-bg @extend .loading-bg .loading-right-bg @extend .loading-bg right : 0 .spinner-box position : fixed z-index : 1001 display : flex justify-content : center align-items : center width : 100% height : 100vh .configure-border-1 position : absolute padding : 3px width : 115px height : 115px background : #ffab91 animation : configure-clockwise 3s ease-in-out 0s infinite alternate .configure-border-2 left : -115px padding : 3px width : 115px height : 115px background : rgb(63 , 249 , 220 ) transform : rotate(45deg ) animation : configure-xclockwise 3s ease-in-out 0s infinite alternate .loading-word position : absolute color : var(--preloader-color) font-size : .8rem .configure-core width : 100% height : 100% background-color : var(--preloader-bg) &.loaded .loading-left-bg transition : all .5s transform : translate(-100% , 0 ) .loading-right-bg transition : all .5s transform : translate(100% , 0 ) .spinner-box display : none @keyframes configure-clockwise 0% transform : rotate(0 ) 25% transform : rotate(90deg ) 50% transform : rotate(180deg ) 75% transform : rotate(270deg ) 100% transform : rotate(360deg ) @keyframes configure-xclockwise 0% transform : rotate(45deg ) 25% transform : rotate(-45deg ) 50% transform : rotate(-135deg ) 75% transform : rotate(-225deg ) 100% transform : rotate(-315deg )
复制以下代码替换全部内容：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 if hexo-config('preloader.enable' ) if hexo-config('preloader.load_style' ) == 'gear' @import './_load_style/gear' else if hexo-config('preloader.load_style' ) == 'ironheart' @import './_load_style/ironheart' else if hexo-config('preloader.load_style' ) == 'scarecrow' @import './_load_style/scarecrow' else if hexo-config('preloader.load_style' ) == 'triangles' @import './_load_style/triangles' else if hexo-config('preloader.load_style' ) == 'wizard' @import './_load_style/wizard' else if hexo-config('preloader.load_style' ) == 'image' @import './_load_style/image' else @import './_load_style/default'
几个if的判断机制与loading.pug类似，都是根据配置项来决定加载的样式。且默认使用旋转盒子动画。
四、创建动画样式模板文件夹 新建动画样式模板存放的文件夹，如无特别提示，所有动画样式均存放在[Blogroot]\themes\butterfly\source\css\_load_style\目录下
1. default 新建[Blogroot]\themes\butterfly\source\css\_load_style\default.styl

五、修改layout.pug 修改[Blogroot]\themes\butterfly\layout\includes\layout.pug
以适配接下来需要添加的配置项。
【注意】butterfly主题v3.6.0及之后版本里，该文件代码稍有不同(如下所示)，但修改的东西都是一样的。该部分代码在文件的最上方大概10行左右的位置。红色-代表需删除的代码行绿色+代表需添加的代码行
butterfly_v3.0.0-v3.5.1
1 2 3 4 body - if theme.preloader + if theme.preloader.enable !=partial('includes/loading/loading', {}, {cache:theme.fragment_cache})
butterfly_v3.6.0+
1 2 3 4 body - if theme.preloader + if theme.preloader.enable !=partial('includes/loading/loading', {}, {cache: true})
六、修改var.styl 修改[Blogroot]\themes\butterfly\source\css\var.styl
添加自定义修改背景色的配置项。(大概98行的位置)
1 2 3 4 // preloader - $preloader-bg = #37474f + $preloader-bg = hexo-config('preloader.enable') && hexo-config('preloader.load_color') ? convert(hexo-config('preloader.load_color')) : #37474f $preloader-word-color = #fff
七、修改_config.butterfly.yml 修改 [Blogroot]\_config.butterfly.yml 的 preloader 配置项。
有些版本的主题配置文件是[Blogroot]\themes\butterfly\_config.yml
修改前的默认代码：
需要删改的代码：
1 2 3 4 5 6 7 # Loading Animation (加載動畫) - preloader: true + preloader: + enable: true # true|false + load_color: '#000000' # '#37474f' + load_style: wizard # default|gear|ironheart|scarecrow|triangles|wizard|image + load_image: # url
修改后：
1 2 3 4 5 6 preloader: enable: true load_color: '#000000' load_style: wizard load_image:
【配置项参数说明】：
enable：控制加载动画的开关，取值有true和false，true开启，false关闭。
load_color：该配置项为自定义加载动画背景颜色。默认值为#37474f,使用时注意用单引号''包起来，不然会被识别成注释符。这个配置项最大的作用是配合load_image使用的图片的背景色，可以用取色器提取自定义图片的主要色调，以达到图片和背景融为一体的效果。
load_style：控制加载动画的样式，目前提供七种类型。预览见步骤2。
default是主题原版的盒子加载动画gear是旋转齿轮加载动画ironheart是钢铁侠核心加载动画scarecrow是稻草人跳动加载动画triangles是旋转三角加载动画wizard是巫师施法加载动画image为自定义添加静态图片或gif作为加载动画。
load_image：该配置项的生效前提是load_style设置为image,内容填写图床链接或者本地相对地址。
熟悉魔改思路以后可以自定义添加更多更多样式，按照本教程的思路，在编译时只会加载选择的加载动画的对应样式，所以不用担心资源占用过多的问题。
最后执行 Hexo 命令三连，hexo clean、hexo g、hexo s，即可看到效果
八、夜间模式匹配(非必要) 此项为非必要修改项 ，主要是为了避免使用image主题的加载动画时，切换夜间模式后，背景色被强制覆盖为黑色，。（说白了就是治疗强迫症）
修改 [Blogroot]\themes\butterfly\source\css\_mode\darkmode.styl
第10行的 --preloader-bg: darken(#121212, 2)
1 2 3 4 5 6 --search-input-color: alpha(#FFFFFF, .7) --search-result-title: alpha(#FFFFFF, .9) - --preloader-bg: darken(#121212, 2) + --preloader-bg: darken(#ca3b3e, -2) --preloader-color: alpha(#FFFFFF, .7) --tab-border-color: #2c2c2c
其中#ca3b3e是设置为image主题时，切换为夜间模式后，自定义图片的背景色值。（切换夜间模式时，整个页面会降低色调，所以连带着自定义图片的色值也变暗，需要重新取值。）
九、【问题解答】 （以下解答来源于 Akilar 博客教程评论区）
1. 超时自动结束
很多同学表示添加了加载动画以后加载半天，只能看动画却进不了站。这点主要是因为加载动画的关闭与否是与网站加载状态的load的返回值决定的，而网站加载完成与否这个概念是很暧昧的，如果加装了pwa，清空缓存后再次加载的内容可能比想象的要多。以下提供两种方案，一个超时自动结束，一个手动点击结束。两者兼容，你可以同时使用达到多重保险。
可以给加载动画设置一个settimeout()的函数来达到伪·加载完毕的效果，即超时了自动关闭加载动画，即使页面还在加载。得益于loading-js使用的是原生js，所以可以给script添加async属性实现异步加载，以免阻塞后续HTML渲染。仅仅需要给控制加载动画开关的loading-js.pug添加两行代码即可。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 - script. + script(async). var preloader = { endLoading: () => { document.body.style.overflow = 'auto'; document.getElementById('loading-box').classList.add("loaded") }, initLoading: () => { document.body.style.overflow = ''; document.getElementById('loading-box').classList.remove("loaded") } } window.addEventListener('load',()=> {preloader.endLoading()}) + setTimeout(function(){preloader.endLoading();}, 5000);
其中5000的单位是ms，代表你设置的最大容忍时间。可以自行修改。
这样一来，如果网站在五秒内加载完成，则优先执行window.addEventListener(‘load’,()=> {preloader.endLoading()}),如果超过5秒，则执行 setTimeout(function(){preloader.endLoading();}, 5000);,两者互不干扰。可喜可贺，可喜可贺。
2. 手动点击结束 给整个 loading-box 添加一个点击动作，点击动画就能结束。[Blogroot]\themes\butterfly\layout\includes\loading\loading-js.pug
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 - script. + script(async). var preloader = { endLoading: () => { document.body.style.overflow = 'auto'; document.getElementById('loading-box').classList.add("loaded") }, initLoading: () => { document.body.style.overflow = ''; document.getElementById('loading-box').classList.remove("loaded") } } window.addEventListener('load',()=> {preloader.endLoading()}) + document.getElementById('loading-box').addEventListener('click',()=> {preloader.endLoading()})
3. 去除左右帷幕拉开效果
4. 延长动画时间
【问】怎么弄才可以让它至少加载多少秒,我感觉加载一下就进去了,实际上没加载完.
【答】Akilar ：看补充内容里的超时自动结束，稍微改写下就好了，因为实质上控制关闭的就是preloader.endloading()这个函数方法，你把动作监听改成计时器就行。
修改[Blogroot]\themes\butterfly\layout\includes\loading\loading-js.pug
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 - script. + script(async). var preloader = { endLoading: () => { document.body.style.overflow = 'auto'; document.getElementById('loading-box').classList.add("loaded") }, initLoading: () => { document.body.style.overflow = ''; document.getElementById('loading-box').classList.remove("loaded") } } - window.addEventListener('load',()=> {preloader.endLoading()}) + setTimeout(function(){preloader.endLoading();}, 5000);
5. 动画加载太快
6. 动画过快，图片还没加载完
【问】我也觉得加载太快了，我不知道加载完成不怎么判定的，但是我的加载动画之后背景图会有一小会儿只显示一半（就跟卡住了一样）。如果我把背景图放到本地，hexo s测试加载本地图片就不会这样。说明还是因为图片没有加载完成。所以有什么办法强制多加载一会儿呢？比如至少加载一两秒之类的
【答】Akilar ：这是伪需求啊，图片加载不完是因为图片过大或者网络环境不好。加载动画的绝对时间控制可以用超时函数实现不假，把网页监听动作改成单纯的超时函数就可以，5000的单位是毫秒。
1 2 - window.addEventListener('load',()=> {preloader.endLoading()}) + setTimeout(function(){preloader.endLoading();}, 5000);
但是我还是不建议你这么做。这样就失去加载动画的本质意义了。
7. 淡出动画 加载动画淡出效果，让网站更丝滑
修改[Blogroot]\themes\butterfly\layout\includes\loading\loading-js.pug
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 script(async). var preloader = { endLoading: () => { document.body.style.overflow = 'auto'; document.getElementById('loading-box').style.transition = 'opacity 3s ease 0s' document.getElementById('loading-box').style.opacity = '0' setTimeout(function(){ document.getElementById('loading-box').classList.add("loaded") }, 3000); }, initLoading: () => { document.body.style.overflow = ''; document.getElementById('loading-box').style.transition = ''; document.getElementById('loading-box').style.opacity = '1' document.getElementById('loading-box').classList.remove("loaded") } } window.addEventListener('load',()=> {preloader.endLoading()}) setTimeout(function(){preloader.endLoading();}, 3000);
百里飞洋 ：可以在主题配置文件中搜索pjax，将其enable参数设置为true。开启Pjax能够实现页面的局部刷新而非整体重载资源，在一定程度上能够减少网站反复加载重复资源，从而优化访问体验，让网站更丝滑。（当然，由于网站变“快”了，加载动画的出现时间长度会随之减少。所以，如果你不开启Pjax就可以多“收获”1、2秒的动画时间哈哈）
十、【补充动画】
除了上面教程中的那些动画效果，下面我再进行一些补充，想添加的同学请自行添加。需完成上面步骤，才能进行以下补充动画的添加操作
（1）黏性加载动画 新建 [Blogroot]\themes\butterfly\layout\includes\loading\load_style\gooey.pug
1 2 3 4 #loading-box div.centered div.blob-1 div.blob-2
新建 [Blogroot]\themes\butterfly\source\css\_load_style\gooey.styl
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 #loading-box { background : #000 ; position : fixed; z-index : 1000 ; width : 100vw ; height : 100vh ; overflow : hidden; text-align : center; &.loaded { z-index : -1000 ; } .centered { width : 400px ; height : 400px ; position : absolute; top : 50% ; left : 50% ; transform : translate(-50% , -50% ); background : #000 ; filter : blur(10px ) contrast(20 ); .blob-1 , .blob-2 { width : 70px ; height : 70px ; position : absolute; background : #fff ; border-radius : 50% ; top : 50% ; left : 50% ; transform : translate(-50% , -50% ); } .blob-1 { left : 20% ; animation : osc-l 2.5s ease infinite; } .blob-2 { left : 80% ; animation : osc-r 2.5s ease infinite; background : #0ff ; } } } @keyframes osc-l { 0% { left : 20% ; } 50% { left : 50% ; } 100% { left : 20% ; } } @keyframes osc-r { 0% { left : 80% ; } 50% { left : 50% ; } 100% { left : 80% ; } }
修改 [Blogroot]\_config.butterfly.yml 的 preloader 配置项。
有些版本的主题配置文件是[Blogroot]\themes\butterfly\_config.yml
1 2 3 4 5 6 preloader: enable: true load_color: 'radial-gradient(#353c44, #222931)' load_style: gooey load_image:
别忘了在loading.pug、loading.styl中模仿上面步骤添加对应代码。
最后执行 Hexo 命令三连，hexo clean、hexo g、hexo s，即可看到效果
