問題:
如果在img上直接使用CSS3的border-radius和box-shadow應用在圖片,瀏覽器並不會完全顯示。前面在《jQuery和CSS3給圖片製作圓角》中說過其解決方法,就是把圖片作為背景圖片,這樣我們就可以應用任何樣式來修飾圖片,而且此時瀏覽器也會完美的呈現出來。
解決方法:
要讓瀏覽器能正常渲染影像的圓角和內陰影效果,你需要將影像轉為背景影像來渲染。
<div style="background:url(image.jpg)" no-repeat center center;width:150px;height:150px></div>
一、浮雕樣式
.embossed .image-wrap {
-webkit-box-shadow: inset 0 0 2px rgba(0,0,0,.8), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -7px 0 rgba(0,0,0,.6), inset 0 -9px 0 rgba(255,255,255,.3);
-moz-box-shadow: inset 0 0 2px rgba(0,0,0,.8), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -7px 0 rgba(0,0,0,.6), inset 0 -9px 0 rgba(255,255,255,.3);
box-shadow: inset 0 0 2px rgba(0,0,0,.8), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -7px 0 rgba(0,0,0,.6), inset 0 -9px 0 rgba(255,255,255,.3);
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
二、軟浮雕效果
這也是一種浮雕效果,只是這個效果增加了一點模糊效果
.soft-embossed .image-wrap {
-webkit-box-shadow: inset 0 0 4px rgba(0,0,0,1), inset 0 2px 1px rgba(255,255,255,.5), inset 0 -9px 2px rgba(0,0,0,.6), inset 0 -12px 2px rgba(255,255,255,.3);
-moz-box-shadow: inset 0 0 4px rgba(0,0,0,1), inset 0 2px 1px rgba(255,255,255,.5), inset 0 -9px 2px rgba(0,0,0,.6), inset 0 -12px 2px rgba(255,255,255,.3);
box-shadow: inset 0 0 4px rgba(0,0,0,1), inset 0 2px 1px rgba(255,255,255,.5), inset 0 -9px 2px rgba(0,0,0,.6), inset 0 -12px 2px rgba(255,255,255,.3);
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
三、剪影效果
同樣是box-shadow的inset的值變化,但此例看上去像一種剪影效果。
.cut-out .image-wrap {
-webkit-box-shadow: 0 1px 0 rgba(255,255,255,.2), inset 0 4px 5px rgba(0,0,0,.6), inset 0 1px 0 rgba(0,0,0,.6);
-moz-box-shadow: 0 1px 0 rgba(255,255,255,.2), inset 0 4px 5px rgba(0,0,0,.6), inset 0 1px 0 rgba(0,0,0,.6);
box-shadow: 0 1px 0 rgba(255,255,255,.2), inset 0 4px 5px rgba(0,0,0,.6), inset 0 1px 0 rgba(0,0,0,.6);
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
四、變形和發光效果
在這個效果中,增加了CSS3的transition效果,當你的滑鼠懸停在圖片上時,圖片會從一個圓角圖片轉圓形圖片,並會發光。使用多重box-shadow來模仿發光效果。
.morphing-glowing .image-wrap {
-webkit-transition: 1s;
-moz-transition: 1s;
transition: 1s;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
.morphing-glowing .image-wrap:hover {
-webkit-box-shadow: 0 0 20px rgba(255,255,255,.6), inset 0 0 20px rgba(255,255,255,1);
-moz-box-shadow: 0 0 20px rgba(255,255,255,.6), inset 0 0 20px rgba(255,255,255,1);
box-shadow: 0 0 20px rgba(255,255,255,.6), inset 0 0 20px rgba(255,255,255,1);
-webkit-border-radius: 60em;
-moz-border-radius: 60em;
border-radius: 60em;
}
五、圖片漸變效果
這個效果,在元素的偽類上增加了一個漸變的效果。
.glossy .image-wrap {
-webkit-box-shadow: inset 0 -1px 0 rgba(0,0,0,.5);
-moz-box-shadow: inset 0 -1px 0 rgba(0,0,0,.5);
box-shadow: inset 0 -1px 0 rgba(0,0,0,.5);
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
.glossy .image-wrap:after {
position: absolute;
content: ' ';
width: 100%;
height: 50%;
top: 0;
left: 0;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
background: -moz-linear-gradient(top, rgba(255,255,255,0.7) 0%, rgba(255,255,255,.1) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(255,255,255,0.7)), color-stop(100%,rgba(255,255,255,.1)));
background: -webkit-linear-gradient(top, rgba(255,255,255,0.7) 0%,rgba(255,255,255,.1) 100%);
background: -o-linear-gradient(top, rgba(255,255,255,0.7) 0%,rgba(255,255,255,.1) 100%);
}
六、倒影效果
使用偽類製作了一個倒影效果,並應用hover改變其位置。
.reflection .image-wrap {
-webkit-box-shadow: inset 0 0 1px rgba(0,0,0,.5), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -1px 0 rgba(0,0,0,.5);
-moz-box-shadow: inset 0 0 1px rgba(0,0,0,.5), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -1px 0 rgba(0,0,0,.5);
box-shadow: inset 0 0 1px rgba(0,0,0,.5), inset 0 2px 0 rgba(255,255,255,.5), inset 0 -1px 0 rgba(0,0,0,.5);
-webkit-transition: .5s;
-moz-transition: .5s;
transition: .5s;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
.reflection .image-wrap:after {
position: absolute;
content: ' ';
width: 100%;
height: 30px;
bottom: -31px;
left: 0;
-webkit-border-top-left-radius: 20px;
-webkit-border-top-right-radius: 20px;
-moz-border-radius-topleft: 20px;
-moz-border-radius-topright: 20px;
border-top-left-radius: 20px;
border-top-right-radius: 20px;
background: -moz-linear-gradient(top, rgba(0,0,0,.3) 0%, rgba(255,255,255,0) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(0,0,0,.3)), color-stop(100%,rgba(255,255,255,0)));
background: linear-gradient(top, rgba(0,0,0,.3) 0%,rgba(255,255,255,0) 100%);
}
.reflection .image-wrap:hover {
position: relative;
top: -8px;
}
七、發光和倒影效果
這個效果使用了偽類建立了一個漸變加倒影影像的效果。
.glossy-reflection {
background: #000;
padding: 20px 40px 50px;
color: #fff;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
.glossy-reflection .image-wrap {
-webkit-box-shadow: inset 0 -1px 0 rgba(0,0,0,.5), inset 0 1px 0 rgba(255,255,255,.6);
-moz-box-shadow: inset 0 -1px 0 rgba(0,0,0,.5), inset 0 1px 0 rgba(255,255,255,.6);
box-shadow: inset 0 -1px 0 rgba(0,0,0,.5), inset 0 1px 0 rgba(255,255,255,.6);
-webkit-transition: 1s;
-moz-transition: 1s;
transition: 1s;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
.glossy-reflection .image-wrap:before {
position: absolute;
content: ' ';
width: 100%;
height: 50%;
top: 0;
left: 0;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
background: -moz-linear-gradient(top, rgba(255,255,255,0.7) 0%, rgba(255,255,255,.1) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(255,255,255,0.7)), color-stop(100%,rgba(255,255,255,.1)));
background: linear-gradient(top, rgba(255,255,255,0.7) 0%,rgba(255,255,255,.1) 100%);
}
.glossy-reflection .image-wrap:after {
position: absolute;
content: ' ';
width: 100%;
height: 30px;
bottom: -31px;
left: 0;
-webkit-border-top-left-radius: 20px;
-webkit-border-top-right-radius: 20px;
-moz-border-radius-topleft: 20px;
-moz-border-radius-topright: 20px;
border-top-left-radius: 20px;
border-top-right-radius: 20px;
background: -moz-linear-gradient(top, rgba(230,230,230,.3) 0%, rgba(230,230,230,0) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(230,230,230,.3)), color-stop(100%,rgba(230,230,230,0)));
background: linear-gradient(top, rgba(230,230,230,.3) 0%,rgba(230,230,230,0) 100%);
}
八、變形和著色效果
這個效果使用了徑向漸變和transition,以及偽類製作一種變形和著色效果,當滑鼠懸停在圖片上時,圖片會變成圓形,並著上另一種顏色。
.morphing-tinting .image-wrap {
position: relative;
-webkit-transition: 1s;
-moz-transition: 1s;
transition: 1s;
-webkit-border-radius: 20px;
-moz-border-radius: 20px;
border-radius: 20px;
}
.morphing-tinting .image-wrap:hover {
-webkit-border-radius: 30em;
-moz-border-radius: 30em;
border-radius: 30em;
}
.morphing-tinting .image-wrap:after {
position: absolute;
content: ' ';
width: 100%;
height: 100%;
top: 0;
left: 0;
-webkit-transition: 1s;
-moz-transition: 1s;
transition: 1s;
-webkit-border-radius: 30em;
-moz-border-radius: 30em;
border-radius: 30em;
}
.morphing-tinting .image-wrap:hover:after {
background: -webkit-gradient(radial, 50% 50%, 40, 50% 50%, 80, from(rgba(0,0,0,0)), to(rgba(0,0,0,1)));
background: -moz-radial-gradient(50% 50%, circle, rgba(0,0,0,0) 40px, rgba(0,0,0,1) 80px);
}
九、羽化效果
.feather .image-wrap {
position: relative;
-webkit-border-radius: 30em;
-moz-border-radius: 30em;
border-radius: 30em;
}
.feather .image-wrap:after {
position: absolute;
content: ' ';
width: 100%;
height: 100%;
top: 0;
left: 0;
background: -webkit-gradient(radial, 50% 50%, 50, 50% 50%, 70, from(rgba(255,255,255,0)), to(rgba(255,255,255,1)));
background: -moz-radial-gradient(50% 50%, circle, rgba(255,255,255,0) 50px, rgba(255,255,255,1) 70px);
}
小結:上面就是Web Designer Wall在《CSS3 Image Styles 》一文中給我們帶來的十二種使用CSS3的border-radius、box-shadow、rgba、transition、gradient以及偽類“:before”和“:after”等屬性製作的圖片效果。
