outline-width · CSS 3.0参考手册.chm

# outline-width **版本：CSS3** ### 语法： **outline-width**： thin | medium | thick | *<length>* 相关属性：[outline](#) , [outline-color](#) , [outline-style](#) , [outline-offset](#) ### 取值： thin：定义细轮廓。medium：默认。定义中等的轮廓。thick：定义粗的轮廓。*<length>* ：定义轮廓粗细的值。 ### 说明： outline-width 属性设置元素整个轮廓的宽度，只有当轮廓样式不是 none 时，这个宽度才会起作用。如果样式为 none，宽度实际上会重置为 0。不允许设置负长度值。参见[outline](#)属性。 ### 兼容性： <table><thead><tr><th class="type">类型</th> <th class="type_ie"><img src="https://box.kancloud.cn/2015-09-02_55e5d38747d87.png" alt="IE" />Internet Explorer</th> <th class="type_firefox"><img src="https://box.kancloud.cn/2015-09-02_55e5d38751b57.png" alt="Firefox" />Firefox</th> <th class="type_chrome"><img src="https://box.kancloud.cn/2015-09-02_55e5d38758c81.png" alt="Chrome" />Chrome</th> <th class="type_opera"><img src="https://box.kancloud.cn/2015-09-02_55e5d387619bd.png" alt="Opera" />Opera</th> <th class="type_safari"><img src="https://box.kancloud.cn/2015-09-02_55e5d3876a213.png" alt="Safari" />Safari</th> </tr></thead><tbody><tr><td rowspan="4" class="version">版本</td> <td class="support no"><span>(×)</span>IE6</td> <td class="support yes"><span>(√)</span>Firefox 3.0.10</td> <td class="support yes"><span>(√)</span>Chrome 2.0.x</td> <td class="support yes"><span>(√)</span>Opera 9.64</td> <td class="support yes"><span>(√)</span>Safari 4</td> </tr><tr><td class="support no"><span>(×)</span>IE7</td> <td class="support yes"><span>(√)</span>Firefox 3.5</td> <td></td> <td></td> <td></td> </tr><tr><td class="support yes"><span>(√)</span>IE8</td> <td></td> <td></td> <td></td> <td></td> </tr><tr><td></td> <td></td> <td></td> <td></td> <td></td> </tr></tbody></table> ### 示例： ![](https://box.kancloud.cn/2015-09-02_55e5d387735dd.png) <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><meta http-equiv="Content-Language" content="utf-8" /><meta name="robots" content="all" /><meta name="author" content="Tencent-ISRD" /><meta name="Copyright" content="Tencent" /><title>outline-width</title></head><body><div style="width: 160px;padding: 10px;height: 30px;border: 2px solid black;outline-color:#897048;outline-style:groove;outline-width:2px;outline-offset: 5px;">这绘制的是一个轮廓边框</div></body></html> 复制代码 Copyright © 2009 [Tencent ISD webteam](http://webteam.tencent.com/).
