1.基础表单 :对于基础表单,Bootstrap并未对其做太多的定制性效果设计,仅仅对表单内的fieldset、legend、label标签进行了定制。
fieldset { min-width: 0; padding: 0; margin: 0; border: 0; } legend { display: block; width: 100%; padding: 0; margin-bottom: 20px; font-size: 21px; line-height: inherit; color: #333; border: 0; border-bottom: 1px solid #e5e5e5; } label { display: inline-block; margin-bottom: 5px; font-weight: bold; }
2.水平表单 类名“form-horizontal”
.form-horizontal .control-label, .form-horizontal .radio, .form-horizontal .checkbox, .form-horizontal .radio-inline, .form-horizontal .checkbox-inline { padding-top: 7px; margin-top: 0; margin-bottom: 0; } .form-horizontal .radio, .form-horizontal .checkbox { min-height: 27px; } .form-horizontal .form-group { margin-right: -15px; margin-left: -15px; } .form-horizontal .form-control-static { padding-top: 7px; } @media (min-width: 768px) { .form-horizontal .control-label { text-align: right; } } .form-horizontal .has-feedback .form-control-feedback { top: 0; right: 15px; }
3.内联表单 类名“form-inline”
<form class="form-inline" role="form"> <div class="form-group"> <label class="sr-only" for="exampleInputEmail2">邮箱</label> <input type="email" class="form-control" id="exampleInputEmail2" placeholder="请输入你的邮箱地址"> </div> <div class="form-group"> <label class="sr-only" for="exampleInputPassword2">密码</label> <input type="password" class="form-control" id="exampleInputPassword2" placeholder="请输入你的邮箱密码"> </div> <div class="checkbox"> <label> <input type="checkbox">记住密码 </label> </div> <button type="submit" class="btnbtn-default">进入邮箱</button> </form> <-- .sr-only:给残障人员用的 --> <-- .sr-only { position: absolute; width: 1px; height: 1px; padding: 0; margin: -1px; overflow: hidden; clip: rect(0, 0, 0, 0); border: 0; } -->
表单控件
1.输入框input: 为了让控件在各种表单风格中样式不出错,需要添加类名“form-control”,下面各个表单控件都能加。
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>表单控件——输入框input</title> <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css?1.1.11"> </head> <body> <form role="form"> <div class="form-group"> <input type="email" class="form-control" placeholder="Enter email"> <input type="text" class="form-control" placeholder="Enter Username"> </div> </form> </body> </html>
type类型:text button checkbox date datetime datetime-local img file hidden month number password radio range reset search submit tel time url week hidden
2.下拉选择框select:多行选择设置multiple属性的值为multiple
<form> <div class="form-group"> <select multiple class="form-control"> //如果是下拉框就不要加multiple <option>踢足球</option> <option>游泳</option> <option>慢跑</option> <option>跳舞</option> </select> </div> </form>
3.内联表单 类名“form-inline”
<form class="form-inline" role="form"> <div class="form-group"> <label class="sr-only" for="exampleInputEmail2">邮箱</label> <input type="email" class="form-control" id="exampleInputEmail2" placeholder="请输入你的邮箱地址"> </div> <div class="form-group"> <label class="sr-only" for="exampleInputPassword2">密码</label> <input type="password" class="form-control" id="exampleInputPassword2" placeholder="请输入你的邮箱密码"> </div> <div class="checkbox"> <label> <input type="checkbox">记住密码 </label> </div> <button type="submit" class="btnbtn-default">进入邮箱</button> </form> <-- .sr-only:给残障人员用的 --> <-- .sr-only { position: absolute; width: 1px; height: 1px; padding: 0; margin: -1px; overflow: hidden; clip: rect(0, 0, 0, 0); border: 0; } -->
ea:添加了类名“form-control”类名,则无需设置cols属性。
<form role="form"> <div class="form-group"> <textarea class="form-control" rows="3"></textarea> </div> </form>
示例
4.复选框checkbox和单选择按钮radio:水平排列加类名“checkbox-inline”||类名“radio-inline”
<form role="form"> <div class="form-group"> <textarea class="form-control" rows="3"></textarea> </div> </form>
4.复选框checkbox和单选择按钮radio:水平排列加类名“checkbox-inline”||类名“radio-inline”
<!doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>表单控件——表单控件大小</title> <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css?1.1.11"> </head> <body> <form role="form"> <h3>案例1</h3> <div class="checkbox"> <label> <input type="checkbox" value=""> 记住密码 </label> </div> <div class="radio"> //如果要水平class=“radio-inline” <label> <input type="radio" name="optionsRadios" id="optionsRadios1" value="love" checked> 喜欢 </label> </div> <div class="radio"> //如果要水平class=“radio-inline” <label> <input type="radio" name="optionsRadios" id="optionsRadios2" value="hate"> 不喜欢 </label> </div> </form> </body> </html>
.radio, .checkbox { display: block; min-height: 20px; padding-left: 20px; margin-top: 10px; margin-bottom: 10px; } .radio label, .checkbox label { display: inline; font-weight: normal; cursor: pointer; } .radio input[type="radio"], .radio-inline input[type="radio"], .checkbox input[type="checkbox"], .checkbox-inline input[type="checkbox"] { float: left; margin-left: -20px; } .radio + .radio, .checkbox + .checkbox { margin-top: -5px; }
.radio-inline, .checkbox-inline { display: inline-block; padding-left: 20px; margin-bottom: 0; font-weight: normal; vertical-align: middle; cursor: pointer; } .radio-inline + .radio-inline, .checkbox-inline + .checkbox-inline { margin-top: 0; margin-left: 10px; }
5.控件大小:类名input-sm:让控件比正常大小更小;类名input-lg:让控件比正常大小更大;宽度配合Bootstrap的网格系统
.input-sm { height: 30px; padding: 5px 10px; font-size: 12px; line-height: 1.5; border-radius: 3px; } select.input-sm { height: 30px; line-height: 30px; } textarea.input-sm, select[multiple].input-sm { height: auto; } .input-lg { height: 46px; padding: 10px 16px; font-size: 18px; line-height: 1.33; border-radius: 6px; } select.input-lg { height: 46px; line-height: 46px; } textarea.input-lg, select[multiple].input-lg { height: auto; }
6.表单控件状态(焦点状态):类名form-control
.form-control:focus { border-color: #66afe9; outline: 0; -webkit-box-shadow: inset 0 1px 1pxrgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6); box-shadow: inset 0 1px 1pxrgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6); }
7.表单控件状态(禁用状态):form-control别忘记加①在需要禁用的表单控件上加上“disabled”;②fieldset设置了disabled属性,整个域都将处于被禁用状态。
.form-control[disabled], .form-control[readonly], fieldset[disabled] .form-control { cursor: not-allowed; background-color: #eee; opacity: 1; }
8.表单控件状态(验证状态):1、.has-warning:警告状态(黄色) 2、.has-error:错误状态(红色) 3、.has-success:成功状态(绿色)
:需要类名has-feedback +
9.表单提示信息:"help-block"
.help-block { display: block; margin-top: 5px; margin-bottom: 10px; color: #737373; }
按钮
建议使用button或a标签来制作按钮
1.基本按钮:类名“btn”
.btn { display: inline-block; padding: 6px 12px; margin-bottom: 0; font-size: 14px; font-weight: normal; line-height: 1.42857143; text-align: center; white-space: nowrap; vertical-align: middle; cursor: pointer; -webkit-user-select: none; -moz-user-select: none; -ms-user-select: none; user-select: none; background-image: none; border: 1px solid transparent; border-radius: 4px; }
2.默认按钮: 类名“btn” + 类名“btn-default”
.btn-default { color: #333; background-color: #fff; border-color: #ccc; }
4.按钮大小: .btn-lg:大型按钮 .btn-sm:小型按钮 .btn-cs:超小型按钮
.btn-lg, .btn-group-lg> .btn { padding: 10px 16px; font-size: 18px; line-height: 1.33; border-radius: 6px; } .btn-sm, .btn-group-sm> .btn { padding: 5px 10px; font-size: 12px; line-height: 1.5; border-radius: 3px; } .btn-xs, .btn-group-xs> .btn { padding: 1px 5px; font-size: 12px; line-height: 1.5; border-radius: 3px; }
5.块状按钮: 类名“btn-block”
6.禁用状态: 使用disabled类或disabled属性
图像 1.img-responsive:响应式图片,主要针对于响应式设计 2.img-rounded:圆角图片 3.img-circle:圆形图片 4.img-thumbnail:缩略图片
img { vertical-align: middle; } .img-responsive, .thumbnail>img, .thumbnail a >img, .carousel-inner > .item >img, .carousel-inner > .item > a >img { display: block; max-width: 100%; height: auto; } .img-rounded { border-radius: 6px; } .img-thumbnail { display: inline-block; max-width: 100%; height: auto; padding: 4px; line-height: 1.42857143; background-color: #fff; border: 1px solid #ddd; border-radius: 4px; -webkit-transition: all .2s ease-in-out; transition: all .2s ease-in-out; } .img-circle { border-radius: 50%; }
