HomeWeb Front-endHTML TutorialSome useful new css3 properties that I have used_html/css_WEB-ITnose

        css3刚推出不久,虽然大多数的css3属性在很多流行的浏览器中不支持,但我个人觉得还是要尽量开始慢慢的去了解并使用css3(还有html5),因为我觉得这是一种趋势,它是一种已经被制定的标准。我并不是专门在做前端的,只是有时不得不自己去写这些东西,有时喜欢研究研究这些,所有以上只是我的个人看法。

 

 1、在之前我想在页面做出一个边框为圆角框,貌似需要写挺多css代码的(可能我没了解到更好的办法),在css3里有一个属性创建圆角是非常容易的 ,设置好角度也可以创建一个圆

border-radius:

     
     

 
 css代码:

 

#test

{

text-align:center;

padding:10px 40px; 

background:gray;

width:350px;

border-radius:10px;

-moz-border-radius:10px; /* 为了让老的 Firefox版本支持 */

}

 

html代码:

border-radius 做圆角的例子。

 

 

2、CSS3 边框阴影,之前我都是直接利用图片做背景实现的效果,用css3中的box-shadow属性也可以做到

box-shadow:

   
        
       

 

css代码:

 

#test1

{

box-shadow: 10px 10px 5px #A5A5A5;

 

width:300px;

height:100px;

}

 

html代码:

 

3、css3 支持背景图片可以用多张图片

 

CSS3 多重背景图片

    

     
        

 

.box

{

width:464px;

height:300px;

background:url(test1.jpg) 0 0 no-repeat,url(test2.jpg) 100% 0 no-repeat;

}

 

4、text-overflow 属性规定当文本溢出包含元素时发生的事情。

此属性支持切断容器中的文本,当文本溢出可以给出了一个省略号的特性。


     
    
  

   
 
 .test3 {

   text-overflow:ellipsis;

   overflow:hidden;

   white-space:nowrap;

   border: 1px solid black;

   width: 400px;

   padding: 20px;

   cursor: pointer;

}

#test3:hover {

  white-space: normal;

  color: rgba(0,0,0,1);

  background: #e3e3e3;

  border: 1px solid #666;

}

当这里显示的内容溢出是会有省略号,鼠标移到文本上面会显示所有内容

5. Transition effect, through CSS3, we can change the element when Add effects to elements when transforming from one style to another.

div

{

width:100px;

height:100px;

background:blue;

transition:width 2s, height 2s;

-moz-transition:width 2s, height 2s, -moz-transform 2s; /* Can support Firefox 4 */

-webkit-transition: width 2s, height 2s, -webkit-transform 2s; /* Can support Safari and Chrome */

-o-transition:width 2s, height 2s, -o-transform 2s; /* Can support Opera */

}

div:hover

{

width:200px;

height:200px;

transform:rotate(180deg);

-moz-transform:rotate(180deg); /* Can support Firefox 4 */

-webkit-transform:rotate(180deg); /* Can support Safari and Chrome */

-o-transform:rotate(180deg); /* Can support Opera * /

}

Place the mouse over this area to see the transition effect.
