完成了整体框架的工作,下面开始写一些组件;从按钮开始,设计的思路主要参照 Bootstrap
首先定义按钮的基类 btn
.btn { display: inline-block; font-weight: 400; color: #212529; text-align: center; vertical-align: middle; cursor: pointer; background-color: #fbfbfb; border: 1px solid #ddd; padding: 5px 10px; font-size: 13px; line-height: 1.5; border-radius: 4px; }
定义了常规状态后,我们还需要定义按钮的
hover
、disabled
、active
、focus
的状态:
.btn:focus { outline: 0; } .btn:hover { background-color: #f6f6f6; } .btn:active { background-color: #eee; } .btn:disabled { cursor: not-allowed; background: #f5f5f5; }
下面是按钮的子类,参照 BootStrap ,我也把按钮的子类区分为
Primary
、Success
、Danger
、Info
、Warn
、Link
,下面以Primary
为例,首先定义一般状态下的按钮样式,由于基类样式已经定义了一些一本属性,所以我们只需要定义background-color
、color
、border-color
即可:
.btn-primary { color: #fff; background-color: #1d7ce3; border-color: #1d7ce3; }
同样定义按钮的 hover
、disabled
、active
、focus
的状态:
.btn-primary:hover { color: #fff; background-color: #1c70cc; border-color: #1c70cc; } .btn-primary:active { color: #fff; background-color: #1a68bc; background-color: #1a68bc; } .btn-primary:disabled { background: #74b5fc; }
.btn-success { color: #fff; background-color: #20be44; border-color: #20be44; } .btn-success:hover { color: #fff; background-color: #1da73d; border-color: #1da73d; } .btn-success:active { color: #fff; background-color: #1b9838; border-color: #1d9f3b; } .btn-success:disabled { background: #74e28d; } .btn-danger { color: #fff; background-color: #eb2a2a; border-color: #eb2a2a; } .btn-danger:hover { color: #fff; background-color: #d42a2a; border-color: #d42a2a; } .btn-danger:active { color: #fff; background-color: #b92020; border-color: #b92020; } .btn-danger:disabled { background: #ee7171; } .btn-warning { color: #fff; background-color: #fbc305; border-color: #fbc305; } .btn-warning:hover { color: #fff; background-color: #eab708; border-color: #eab708; } .btn-warning:active { color: #fff; background-color: #d6a707; background-color: #d6a707; } .btn-warning:disabled { background: #fadc77; } .btn-link { color: #1c70cc; border-color: transparent; background: transparent; } .btn-link:hover { text-decoration: underline; background: transparent; } .btn-link:active { color: #e53c0a; } .btn-link:disabled { background: transparent; color: #92c2f6; }
定义了按钮的基本状态后,我们还可以定义按钮的大小:
.btn-large { font-size: 16px; padding: 8px 16px; border-radius: 6px; } .btn-mini { font-size: 8px; padding: 3px 6px; border-radius: 2px; }
.btn-block { display: block; width: 100%; }
