• CSS之第五天绽放


    这些都是新内容,觉得好陌生,要多练才行

    1、background-origin 背景原点,必需保证背景是background-repeat为no-repeat。

    如:html:<div class=”img”></div>

    css:  .img{width=”300px”;

    height=”250”;

    padding=”50px”;

    background:url(...)no-repeat;

    border:50px dashed #ccc;

    background-origion:content-box;

    background-position:center center;

    }

    2、background-clip 背景的显示区域

    如:html:<div class=”img”></div>

    Css:将上面background-origin;替换成background-clip:padding-box;即可。

    3、background-size背景尺寸>

    如:html:<div class=”d1”></div>

    Css:  .d1{background:url(...) no-repeat;

    background-size:80px 60px;

    }

    4、background:背景色 背景图片 背景平铺方式 背景定位

    如body{background:#EDEDED url(...) no-repeat 50% 30px;}

    5、多重背景

    如:html:<div class=”img”></div>

    css:  .img{720px;

    height:461px;

    background:url(...) no-repeat center center/30% 30%,url(...);

    }

    6、list-style-type 项目符号

    如: ul{list-style-type:*}

    *可以是实心圆disc、空心圆circle、实心方块、不显示none、阿拉伯数字decimal、小写罗马数字lower-roman、大写罗马数字upper-roman。

    7.list-style-image 自定义项目符号

    如:ul{list-style-image:url(...)}

    8、transform 变形样式

    如:html:<div class="circle-box"></div>

    CSS:

    2D平移translate():

    .circle-box {

                    100p x;

                    height: 100px;

                    border-radius: 10px;

                    background-color: #808080;

                    /* 移动x,y */

                    /*transform: translate(100%, 100%);*/

                    /* 移动x */

                    /*transform: translateX(200%);*/

                    /* 移动Y */

                    transform: translateY(200%);

                }

    2D旋转 rotate():

                         .circle-box {

                    100px;

                    height: 100px;

                    border-radius: 10px;

                    background-color: #808080;

                    transform-origin: 0 0;

                    transform: rotate(15deg);

                }

    2D缩放 scale():

    .circle-box {

                    100px;

                    height: 100px;

                    background: #000000;

                    transition: all .3s ease-in;

                }

                .circle-box:hover {

                    transform: scale(1.1, 1.1);

                }

    斜切扭曲 skew():

                .circle-box {

                    100px;

                    height: 100px;

                    background: #000000;

                    transition: all .3s ease-in;

                }

                .circle-box:hover {

                    transform: skew(10deg, 10deg);

                }

    3D位移translate3d():

    .circle-box{

             80px;

             height: 46px;

             background-color: #e4ff00;

             position:absolute;left: 473px;top:232px;

             transition:all .3s ease-in;

    }

    .circle-box:hover{

             transform:translate3d(67px,89px,156px);

    }

    9、过渡动画transition:

    如:html:<div class="circle-box"></div>

    CSS:          

     .circle-box {

                    100px;

                    height: 100px;

                    background: #000000;

                    /*transition-property: width,height;

                    transition-duration: .3s;

                    transition-timing-function: ease-in;

                    transition-delay: 1s;*/

                    transition: all .3s ease-in 1s;

                }

               

                .circle-box:hover {
