页面需要一定的 CSS 基本功，虽然现在有很多成熟的框架如 bootstrap 等，我们轻松的就就可以做出一些页面效果。但是掌握每一个常见效果的写法还是很重要的，下面整理出一些常见的 CSS 前端效果，让你更轻松的写页面。
1、禁止选择文本
body {
-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
2、在可打印的网页中显示URLs
@media print {
a:after {
content: " [" attr(href) "] ";
}
}
3、深灰色的点击渐变按钮
.graybtn {
-moz-box-shadow:inset 0px 1px 0px 0px #ffffff;
-webkit-box-shadow:inset 0px 1px 0px 0px #ffffff;
box-shadow:inset 0px 1px 0px 0px #ffffff;
background:-webkit-gradient( linear, left top, left bottombottom, color-stop(0.05, #ffffff), color-stop(1, #d1d1d1) );
background:-moz-linear-gradient( center top, #ffffff 5%, #d1d1d1 100% );
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffffff', endColorstr='#d1d1d1');
background-color:#ffffff;
-moz-border-radius:6px;
-webkit-border-radius:6px;
border-radius:6px;
border:1px solid #dcdcdc;
display:inline-block;
color:#777777;
font-family:arial;
font-size:15px;
font-weight:bold;
padding:6px 24px;
text-decoration:none;
text-shadow:1px 1px 0px #ffffff;
}
.graybtn:hover {
background:-webkit-gradient( linear, left top, left bottombottom, color-stop(0.05, #d1d1d1), color-stop(1, #ffffff) );
background:-moz-linear-gradient( center top, #d1d1d1 5%, #ffffff 100% );
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#d1d1d1', endColorstr='#ffffff');
background-color:#d1d1d1;
}
.graybtn:active {
position:relative;
top:1px;
}
4、网页顶部盒阴影
body:before {
content: "";
position: fixed;
top: -10px;
left: 0;
width: 100%;
height: 10px;
-webkit-box-shadow: 0px 0px 10px rgba(0,0,0,.8);
-moz-box-shadow: 0px 0px 10px rgba(0,0,0,.8);
box-shadow: 0px 0px 10px rgba(0,0,0,.8);
z-index: 100;
}
5、在可点击的项目上强制手型
a[href], input[type='submit'], input[type='image'], label[for], select, button, .pointer {
cursor: pointer;
}
6、CSS3 鲜艳的输入（边框渐变）
input[type=text], textarea {
-webkit-transition: all 0.30s ease-in-out;
-moz-transition: all 0.30s ease-in-out;
-ms-transition: all 0.30s ease-in-out;
-o-transition: all 0.30s ease-in-out;
outline: none;
padding: 3px 0px 3px 3px;
margin: 5px 1px 3px 0px;
border: 1px solid #ddd;
}
input[type=text]:focus, textarea:focus {
box-shadow: 0 0 5px rgba(81, 203, 238, 1);
padding: 3px 0px 3px 3px;
margin: 5px 1px 3px 0px;
border: 1px solid rgba(81, 203, 238, 1);
}
7、三角形列表项目符号
ul {
margin: 0.75em 0;
padding: 0 1em;
list-style: none;
}
li:before {
content: "";
border-color: transparent #111;
border-style: solid;
border-width: 0.35em 0 0.35em 0.45em;
display: block;
height: 0;
width: 0;
left: -1em;
top: 0.9em;
position: relative;
}
8、内部CSS3 盒阴影
#mydiv {
-moz-box-shadow: inset 2px 0 4px #000;
-webkit-box-shadow: inset 2px 0 4px #000;
box-shadow: inset 2px 0 4px #000;
}
9、外部CSS3 盒阴影
#mydiv {
-webkit-box-shadow: 0 2px 2px -2px rgba(0, 0, 0, 0.52);
-moz-box-shadow: 0 2px 2px -2px rgba(0, 0, 0, 0.52);
box-shadow: 0 2px 2px -2px rgba(0, 0, 0, 0.52);
}
10、@font-face模板
@font-face {
font-family: 'MyWebFont';
src: url('webfont.eot'); /* IE9 Compat Modes */
src: url('webfont.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
url('webfont.woff') format('woff'), /* Modern Browsers */
url('webfont.ttf') format('truetype'), /* Safari, Android, iOS */
url('webfont.svg#svgFontName') format('svg'); /* Legacy iOS */
}
body {
font-family: 'MyWebFont', Arial, sans-serif;
}
11、CSS3渐变模板
#colorbox {
background: #629721;
background-image: -webkit-gradient(linear, left top, left bottombottom, from(#83b842), to(#629721));
background-image: -webkit-linear-gradient(top, #83b842, #629721);
background-image: -moz-linear-gradient(top, #83b842, #629721);
background-image: -ms-linear-gradient(top, #83b842, #629721);
background-image: -o-linear-gradient(top, #83b842, #629721);
background-image: linear-gradient(top, #83b842, #629721);
}
12、CSS3：全屏背景
html {
background: url('images/bg.jpg') no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
13、锚链接伪类
a:link { color: blue; }
a:visited { color: purple; }
a:hover { color: red; }
a:active { color: yellow; }
14、图片边框偏光
img.polaroid {
background:#000; /*Change this to a background image or remove*/
border:solid #fff;
border-width:6px 6px 20px 6px;
box-shadow:1px 1px 5px #333; /* Standard blur at 5px. Increase for more depth */
-webkit-box-shadow:1px 1px 5px #333;
-moz-box-shadow:1px 1px 5px #333;
height:200px; /*Set to height of your image or desired div*/
width:200px; /*Set to width of your image or desired div*/
}
15、通用媒体查询
/* Smartphones (portrait and landscape) ----------- */
@media only screen
and (min-device-width : 320px) and (max-device-width : 480px) {
/* Styles */
}
/* Smartphones (landscape) ----------- */
@media only screen and (min-width : 321px) {
/* Styles */
}
/* Smartphones (portrait) ----------- */
@media only screen and (max-width : 320px) {
/* Styles */
}
/* iPads (portrait and landscape) ----------- */
@media only screen and (min-device-width : 768px) and (max-device-width : 1024px) {
/* Styles */
}
/* iPads (landscape) ----------- */
@media only screen and (min-device-width : 768px) and (max-device-width : 1024px) and (orientation : landscape) {
/* Styles */
}
/* iPads (portrait) ----------- */
@media only screen and (min-device-width : 768px) and (max-device-width : 1024px) and (orientation : portrait) {
/* Styles */
}
/* Desktops and laptops ----------- */
@media only screen and (min-width : 1224px) {
/* Styles */
}
/* Large screens ----------- */
@media only screen and (min-width : 1824px) {
/* Styles */
}
/* iPhone 4 ----------- */
@media only screen and (-webkit-min-device-pixel-ratio:1.5), only screen and (min-device-pixel-ratio:1.5) {
/* Styles */
}
16、跨浏览器透明
.transparent {
filter: alpha(opacity=50); /* internet explorer */
-khtml-opacity: 0.5; /* khtml, old safari */
-moz-opacity: 0.5; /* mozilla, netscape */
opacity: 0.5; /* fx, safari, opera */
}
17、用CSS动画实现省略号动画
.loading:after {
overflow: hidden;
display: inline-block;
vertical-align: bottombottom;
animation: ellipsis 2s infinite;
content: "26"; /* ascii code for the ellipsis character */
}
@keyframes ellipsis {
from {
width: 2px;
}
to {
width: 15px;
}
}
18、制造模糊文本
.blurry-text {
color: transparent;
text-shadow: 0 0 5px rgba(0,0,0,0.5);
}
19、包裹长文本 文本过长自动换行不会穿破盒子
pre {
whitewhite-space: pre-line;
word-wrap: break-word;
}
20、背景渐变色
button {
background-image: linear-gradient(#5187c4, #1c2f45);
background-size: auto 200%;
background-position: 0 100%;
transition: background-position 0.5s;
}
button:hover {
background-position: 0 0;
}
21、内容可编辑（contenteditable="true"）
<ul contenteditable="true">
<li>悼念遇难香港同胞 </li>
<li>深圳特区30周年</li>
<li>伊春空难</li>
</ul>
22、输入框改变placeholder字体颜色
::-webkit-input-placeholder {
color: red;
}
:-moz-placeholder {
color: red;
}
::-moz-placeholder{
color: red;
}
:-ms-input-placeholder {
color: red;
}
