跨瀏覽器透明度設(shè)置
.transparent { -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";/* IE 8 */ filter: alpha(opacity=50); /* IE 5-7 */ -moz-opacity: 0.5;/* Netscape */ -khtml-opacity: 0.5; /* Safari 1.x */ opacity: 0.5; /* Good browsers */ }
常規(guī)媒體查詢
/* Smartphones (portrait and landscape) ----------- */ @media only screen and (min-device-width : 320px) and (max-device-width : 480px) { } /* Smartphones (landscape) ----------- */ @media only screen and (min-width : 321px) { } /* Smartphones (portrait) ----------- */ @media only screen and (max-width : 320px) { } /* iPads (portrait and landscape) ----------- */ @media only screen and (min-device-width : 768px) and (max-device-width : 1024px) { } /* iPads (landscape) ----------- */ @media only screen and (min-device-width : 768px) and (max-device-width : 1024px) and (orientation : landscape) { } /* iPads (portrait) ----------- */ @media only screen and (min-device-width : 768px) and (max-device-width : 1024px) and (orientation : portrait) { } /* Desktops and laptops ----------- */ @media only screen and (min-width : 1224px) { } /* Large screens ----------- */ @media only screen and (min-width : 1824px) { } /* iPhone 4 ----------- */ @media only screen and (-webkit-min-device-pixel-ratio:1.5), only screen and (min-device-pixel-ratio:1.5) { }
自定義選中文本
::selection { background: #51a351; } ::-moz-selection { background: #51a351; } ::-webkit-selection { background: #51a351; }
帶CSS3的全屏背景
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; }
強制垂直滾動條
html { height: 101% }
文本首字母大寫
p:first-letter { display: block; margin: 4px 0 0 4px; float: left; color: #ff3366; font-size: 5.3em; font-family: Georgia, Times New Roman, serif; }
內(nèi)外陰影
#mydiv { -moz-box-shadow: inset 2px 0 4px #000; -webkit-box-shadow: inset 2px 0 4px #000; box-shadow: inset 2px 0 4px #000; }
#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); }
語音氣泡
.speech-bubble { position: relative; background: #00aabb; border-radius: .4em; } .speech-bubble:after { content: ''; position: absolute; bottom: 0; left: 50%; width: 0; height: 0; border: 30px solid transparent; border-top-color: #00aabb; border-bottom: 0; border-left: 0; margin-left: -15px; margin-bottom: -30px; }
自定義輸入樣式
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); }
