请教高手几个问题_html/css_WEB-ITnose

 请问高手,css中display这个属性它有什么作用?另外想问下,ul这个列表,有什么用途?不用写

    直接写
  • 可以么?ul和li的区别在哪里?另外,有些网站的链接广告使用了大量的ul这是为什么?为什么不用表格定位编写链接而用ul?

    1、用处多了,简单的隐藏元素,或将块元素转换为内联元素或反之,等等太多了。
    2、一般理解为有语义的不关心显示顺序的列表元素。如报名薄这时候不太关心顺序。但ol就不一样,它关心显示顺序,如按学生成绩排名就比较适合用ol
    3、这要怎么看,一般情况下是不允许的,因为它不符合dtd的规定。如果你将li定义为table-cell的话,从css角度来看正确,但从html的角度来看不正确。
    4、要说区别,一个是包含块,li是子元素,li内容前默认有标志符合,但ul元素本身没有。
    5、这个要因人而异了,多说人会解释为有语意的html.这个很难说别人使用ul一定正确(其实也没有对错之分,就像w3c中有些不清楚的描述部分一样,各个浏览的实现就不一致),如你更喜欢用标题元素(h1,h2),但有些人更喜欢用p,所以不好说。
    6、同5

    楼上正解,display就是隐藏和显示属性,ul, li是列表,一般是ul包含li这才是规范的写法

    高就谈不上,混口饭吃。
    在浙江。非省会。
    非知名it企业,所以薪水你懂的。

    非知名it企业,所以薪水你懂的。??我不懂。

    使用这一类块元素,不仅容易布局,而且搜索引擎喜欢这个元素,利于seo优化

    请问高手,html中如何区分块元素和行元素?
