0.设计原理

①给一系列的css属性起名字如dark表示黑夜，默认为失效不显示 ②页面上增加左侧主题切换按钮,按钮处理逻辑为将所有dark对应的css属性启用，并设置标记位

1.增加主题切换按钮及其js处理逻辑

位置:themes/sakura/layout/layout.ejs 这个文件会在所有页面生效

内容如下:（ps:多了个大红灯笼的div）

  <!-- 8.增加红灯笼按钮-->
       <!--深夜模式按钮-->
  <a onclick="switchNightMode()" id="sma"> 
	<i class="fa fa-moon-o" id="nightMode" aria-hidden="true"></i> 
  </a>
       <!--圣诞模式按钮-->  
	   <script>
    if (localStorage.getItem('themechris') === '1') {
    document.body.classList.add('themechris');
    }
    else if (matchMedia('(prefers-color-scheme: themechris)').matches) {
    document.body.classList.add('themechris');
    }
	</script>
  <a onclick="switchChrisThemes()" id="switchchristmas">

       <!--春节模式按钮-->

    if (localStorage.getItem('themespring') === '1') {

    }
    else if (matchMedia('(prefers-color-scheme: themespring)').matches) {
    document.body.classList.add('themespring');
    }
</script>
  <div onclick="switchSpringThemes()" id="switchspring">

            </div>
        </div>
    </div>
  <!--春节主题大红灯笼-->
       <script>
	   // 切换深色模式JS
	   function switchNightMode() {
			var body = document.body;

				return; 
			} 
	   }
	       // 中国节日按钮切换
	
    function switchSpringThemes() {
        var body = document.body;
        if(body.classList.contains('themechris')){
            document.body.classList.remove('themechris');
            localStorage.setItem('themechris','0');
            document.body.classList.add('themespring');
            localStorage.setItem('themespring','1');
            return;
        }
        if(body.classList.contains('themespring')){
        document.body.classList.remove('themespring');
        localStorage.setItem('themespring','0');
        return;
        } else {
        document.body.classList.add('themespring');
        localStorage.setItem('themespring','1');
		
        return;
        }
    };

    // 圣诞节按钮切换
    function switchChrisThemes() {
        var body = document.body;
        if(body.classList.contains('themespring')){
            document.body.classList.remove('themespring');
            localStorage.setItem('themespring','0');
            document.body.classList.add('themechris');
            localStorage.setItem('themechris','1');
            return;
        }
        if(body.classList.contains('themechris')){
        document.body.classList.remove('themechris');
        localStorage.setItem('themechris','0');
        return;
        } else {
        document.body.classList.add('themechris');
        localStorage.setItem('themechris','1');
        return;
        }
    };
	</script>

2.增加对应主题的css样式和按钮的css样式

位置:thems/sakura/source/css/style.css

内容如下:

3.在需要的位置加上挂件

当我们点击切换按钮时就会显示对应模式下的挂件,//挂件图片可自己替换

挂件示例:

 <!--可以在你想要展示小挂件的地方加上这个挂件，还没有完善等之后再进行吧-->
  <!--圣诞主题小挂件-->
	<div class="caishendengsd">        
		<div class="caishenxiansd">
			<img class="caishenpicsd" src="https://hesifan.top/medias/christmas-img/2.png">
		</div>              
	</div>
  <!-圣诞主题小挂件结束-->
 <!--春节主题小挂件-->
<div class="caishendeng">        
	<div class="caishenxianleft">
		<img class="caishenpic fudai" src="https://hesifan.top/medias/spring-img/3.png">
	</div>              
</div>
  <!-春节主题小挂件结束-->
