写在前面
写的一模一样的css样式,结果却导致原来出来不一样的效果图。
用chrome的开发者工具查看,比较起来还是一模一样的css样式,可为什么会出现不一样的placeholder效果呢?一个白色粗体,一个灰色正常字体。
找了老半天找不到原因
后来才发现是我同事写的框架css里面代码的一句话影响到了
::-webkit-input-placeholder { color: #a4afc6; }
可是为什么在chrome控制台看不到这句代码呢?请教了一番同事,原来是这样的。
1、点击控制台“设置”按钮
2、按如下所示设置,选中“Show user agent shadow DOM”
3、你就会在elements控制面板里面能看到如下所示
回归正题,继续我的css各种图标。。。。
当然在开始之前,还是加上如下这段公共样式吧!
[class^="u-icon"] { display: inline-block; color: #fff; vertical-align: middle; }
各种删除按钮(不用图标只能css来实现)
html代码如下:
<span class="u-icon-radioDelete"></span> <span class="u-icon-deleteToggle Orange"> <span class="u-icon-trash"></span>删除 </span> <span class="u-icon-deleteToggle Blue"> <span class="u-icon-grayTrash"></span>删除 </span> <span class="u-icon-del"></span> <span class="u-icon-del on"></span> <span class=‘u-icon-sel more‘>搜索更多</span> <span class=‘u-icon-sel on‘>搜索更多</span> <span class=‘u-icon-delete‘><i></i></span>
页面显示效果如下:
css样式代码:
.u-icon-sel { position: relative; -webkit-box-sizing: border-box; width: 32%; height: 32px; line-height: 30px; margin-bottom: 4px; border: 1px solid #a4afc6; border-radius: 3px; color: #a4afc6; text-align: center; text-overflow: ellipsis; overflow: hidden; white-space: nowrap; } .u-icon-sel.on { overflow: hidden; border-color: #ff5d1d; color: #000; } .u-icon-sel.on:before { position: absolute; right: 0; bottom: 0; width: 18px; height: 18px; background: url(http://webresource.c-ctrip.com/ResCorpMobile/R1/img/common-graphic37.png?20150423) no-repeat -23px -152px/150px 240px; content: ‘‘; } .u-icon-sel.more { color: #6daeee; } .u-icon-deleteToggle { width: 75px; height: 45px; line-height: 45px; text-align: center; } .u-icon-deleteToggle.Blue { background-color: #3e74b9; } .u-icon-deleteToggle.Orange { background-color: #ff5d1d; } /*白色垃圾桶、灰色垃圾桶图标*/ .u-icon-trash,.u-icon-grayTrash { background: url(http://webresource.c-ctrip.com/ResCorpMobile/R1/img/common-graphic37.png?20150423) no-repeat 0 0/150px 240px; } .u-icon-trash { background-position: 0 -84px; width: 16px; height: 18px; } .u-icon-grayTrash { display: inline-block; width: 12px; height: 18px; margin-right: 8px; vertical-align: -2px; background-position: -3px -178px; } /*不用任何图标实现删除icon效果*/ .u-icon-delete { position: absolute; bottom: 5px; right: 0; width: 40px; height: 40px; } /*给before伪类设置一个默认背景色 设置content*/ .u-icon-delete:before { position: absolute; top: 10px; left: 10px; width: 20px; height: 20px; border-radius: 20px; background-color: #8e8e93; content: ‘‘; } /*给after伪类 -webkit-transform: rotate(-45deg);旋转 background-color: #e1e2e4;设置X的一边的颜色*/ .u-icon-delete:after { position: absolute; top: 19px; left: 14px; width: 12px; height: 2px; -webkit-transform: rotate(-45deg); background-color: #e1e2e4; content: ‘‘; } /* -webkit-transform: rotate(45deg); 运用的特别巧秒*/ .u-icon-delete i { position: absolute; top: 19px; left: 14px; width: 12px; height: 2px; background-color: #e1e2e4; -webkit-transform: rotate(45deg); } /*橙色背景中间一白色横杠的删除icon */ .u-icon-del { position: relative; width: 24px; height: 24px; border: 1px solid #ff5d1d; -webkit-border-radius: 24px; border-radius: 24px; -webkit-transition: 300ms ease-in-out; transition: 300ms ease-in-out; background-color: #ff5d1d; } .u-icon-del.on,.on .u-icon-del { -webkit-transform: rotateZ(90deg); } /*这里的background-color: #fff;和 content: "\20";实现白色横杠*/ .u-icon-del::after { position: absolute; top: 10px; left: 4px; width: 16px; height: 4px; background-color: #fff; content: "\20"; } .u-icon-radioDelete { position: relative; width: 24px; height: 24px; border: 1px solid #8AADD8; -webkit-border-radius: 24px; border-radius: 24px; -webkit-transition: 300ms ease-in-out; transition: 300ms ease-in-out; } .u-icon-radioDelete::after { position: absolute; top: 11px; left: 4px; width: 16px; height: 2px; background-color: #8AADD8; color: #8AADD8; content: "\20"; } .u-icon-radioDelete.on,.on .u-icon-radioDelete { -webkit-transform: rotateZ(90deg); -ms-transform: rotateZ(90deg); }
加加减减图标
