div class="locked"什么意思
定义一个div元素 类别是image
div是一个html元素,他没有边届,没有附属样式,常用来布局页面。
class是一个样式选择器名称,class是一个类别,在css中对应“.类名”。和class一起的还有id,在css中对应“#类名”。类是一个类别,可多次使用,多个元素使用他。id是特例,只能使用一次。
如果给一个元素写个类名用来赋予样式,则可以这样写:
1.<div class="big_text"></div>只有一个类名
2.<div class="red_text big_text"></div>可以是两个类叠加的样式
3.<div class="red_text big_text" id="title"></div>可以是多个类叠加,并且区分开其他同类型
4.<p class="cont"></p>可以给任何元素使用样式选择
5.<img class="tips" />可以给任何元素使用样式选择
6.<hr id="litend" />名字可以随便定义
div class="locked"什么意思?
这就是定义一个div的class属性是locked,就是这个class的名字叫locked。locked本身没有含义,只是个英文单词。。。。一般是在css里控制这整个div用的。

没有什么意思
表示建立一个层,一个包含框class="shadow"表示给这个层起一个名为shadow的类 名称,
然后css中可以调用.shadow{width:100px;height:100px;background:red}等之类的样式
