SVG动画实现文本纹理动态效果
SVG
如果要对文本纹理做更精密的设置，且考虑浏览器兼容性，最好的方案还是使用SVG文本
首先，可以通过SVG动画，来实现文本纹理的动态效果
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> </head> <body> <svg height="100" xmlns="http://www.w3.org/2000/svg" id="svg"> <defs> <style> .text{font:bolder 50px/100px Impact;} </style> <radialGradient id="Gradient1"> <animate attributeName="r" values="0%;150%;100%;0%" dur="5" repeatCount="indefinite" /> <stop offset="0%" stop-color="#fff"> <animate attributeName="stop-color" values="#333;#FFF;#FFF;#333" dur="5" repeatCount="indefinite" /> </stop> <stop offset="100%" stop-color="rgba(55,55,55,0)"/> </radialGradient> </defs> <text class="text" dominant-baseline="hanging" y="10" x="0" fill="url(#Gradient1)">期权记</text> </svg> </body> </html> 使用SVG图案pattern，可以实现更精细的纹理动画效果
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> </head> <body> <svg height="100" xmlns="http://www.w3.org/2000/svg" id="svg"> <defs> <style> .text{font:bolder 100px/100px Impact;} @keyframes stroke { 50% { stroke-width:30; stroke-opacity: .5; } } .g-spots circle{stroke-width: 0;animation: stroke 2s infinite;} .g-spots circle:nth-child(1) {animation-delay: -0.4s;} .g-spots circle:nth-child(2) {animation-delay: -1.2s;} </style> <pattern id="p-spots" width="0.12" height="0.2"> <g class="g-spots"> <circle r="10" cx="10" cy="5" fill="#3F0B1B" stroke="#3F0B1B" /> <circle r="10" cx="25" cy="20" fill="#CF423C" stroke="#CF423C"/> </g> </pattern> </defs> <text class="text" dominant-baseline="hanging" y="10" x="0" stroke="url(#p-spots)" fill="none" stroke-width="5" stroke-opacity="0.5">期权记</text> </svg> </body> </html> 
如果想实现虚线动画的效果，则需要使用SVG文本的虚线描边
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> </head> <body> <svg height="100" xmlns="http://www.w3.org/2000/svg" id="svg"> <defs> <style> @keyframes stroke {100% { stroke-dashoffset: -400;}} .text{font:bolder 95px/100px Impact;} .use-text{fill: none;stroke-width: 6;stroke-dasharray: 70 330;stroke-dashoffset: 0;animation: stroke 6s infinite linear;} .use-text:nth-child(5n+1){stroke: pink;animation-delay: -1.2s;} .use-text:nth-child(5n+2){stroke: lightblue;animation-delay: -2.4s;} .use-text:nth-child(5n+3){stroke: lightgreen;animation-delay: -3.6s;} .use-text:nth-child(5n+4){stroke: orange;animation-delay: -4.8s;} .use-text:nth-child(5n+5){stroke: tan;animation-delay: -6s;} </style> </defs> <symbol id="s-text"> <text class="text" dominant-baseline="hanging" y="10" x="0" >例子03</text> </symbol> <use xlink:href="#s-text" class="use-text"></use> <use xlink:href="#s-text" class="use-text"></use> <use xlink:href="#s-text" class="use-text"></use> <use xlink:href="#s-text" class="use-text"></use> <use xlink:href="#s-text" class="use-text"></use> </svg> </body> </html>
