我想为表单创建一些体面的输入,而且我真的很想知道TWITTER如何在输入周围做发光的边框。

Twitter边框的示例/图片:

在此处输入图片说明

我也不太了解如何创建圆角。

干得好:

.glowing-border {
    border: 2px solid #dadada;
    border-radius: 7px;
}

.glowing-border:focus { 
    outline: none;
    border-color: #9ecaed;
    box-shadow: 0 0 10px #9ecaed;
}

(要查看演示代码,请从URL中删除“ show /”)

label { 
    display:block;
    margin:20px;
    width:420px;
    overflow:auto;
    font-family:sans-serif;
    font-size:20px;
    color:#444;
    text-shadow:0 0 2px #ddd;
    padding:20px 10px 10px 0;
}

input {
    float:right;
    width:200px;
    border:2px solid #dadada;
    border-radius:7px;
    font-size:20px;
    padding:5px;
    margin-top:-10px;    
}

input:focus { 
    outline:none;
    border-color:#9ecaed;
    box-shadow:0 0 10px #9ecaed;
}

我如何为发光设置动画?

@NSElvis如transition: box-shadow linear 1s jsfiddle.net/simevidas/6LyWe/1

非常好。一件事,如果只希望将其应用于文本输入字段,则将要限制选择器:input [type = text]:focus,input [type = password],input [type = textarea]。

@MichaelKennedy在现实世界的应用程序中,这还不够。标准方法是类,例如.glowing-input { … }
森那维达斯

当然,我的意思是将其应用于可能不需要的单选按钮,提交按钮等。

这样的事情怎么样... http://jsfiddle.net/UnsungHero97/Qwpq4/1207/

在此处输入图片说明

的CSS

input {
    border: 1px solid #4195fc; /* some kind of blue border */

    /* other CSS styles */

    /* round the corners */
    -webkit-border-radius: 4px;
       -moz-border-radius: 4px;
            border-radius: 4px;


    /* make it glow! */
    -webkit-box-shadow: 0px 0px 4px #4195fc;
       -moz-box-shadow: 0px 0px 4px #4195fc;
            box-shadow: 0px 0px 4px #4195fc; /* some variation of blue for the shadow */

}

这并没有放松进来

所以呢?接受的答案并不能缓解问题。最初的问题(和我的答案)发布于2011年,我很确定Twitter的发光边界也不会放松。此外,问题不在于缓和性,而在于如何使边界具有圆角的光泽,我已经回答了。我认为您不应该因为没有轻松解决问题而对我投反对票

使用普通的蓝色border,中等border-radius和蓝色box-shadow的位置0 0

SLaks触手可及,但您通常可能希望查看CSS3中输入的更改。圆角和矩形阴影都是CSS3中的新功能,它们将使您能够准确地完成所需的工作。我个人最喜欢的CSS3 / HTML5链接之一是http://diveintohtml5.ep.io/

我结合了前面的两个答案(jsfiddle)。

input {
    /* round the corners */
    border-radius: 4px;
    -moz-border-radius: 4px;
    -webkit-border-radius: 4px;    
}

input:focus { 
    outline:none;
    border: 1px solid #4195fc; 
    /* create a BIG glow */
    box-shadow: 0px 0px 14px #4195fc; 
    -moz-box-shadow: 0px 0px 14px #4195fc;
    -webkit-box-shadow: 0px 0px 14px #4195fc;  
}​

修改后的版本少了发光的版本。

input {
    /* round the corners */
    //background-color: transparent;
    border: 1px solid;
    height: 20px;
    width: 160px;
    color: #CCC;
    border-radius: 4px;
    -moz-border-radius: 4px;
    -webkit-border-radius: 4px;    
}

input:focus { 
    outline:none;
    border: 1px solid #4195fc; 
    /* create a BIG glow */
    box-shadow: 0px 0px 5px #4195fc; 
    -moz-box-shadow: 0px 0px 5px #4195fc;
    -webkit-box-shadow: 0px 0px 5px #4195fc;  
}

input[type="text"]{
   @include transition(all 0.30s ease-in-out);
  outline: none;
  padding: 3px 0px 3px 3px;
  margin: 5px 1px 3px 0px;
  border: 1px solid #DDDDDD;
}
input[type="text"]:focus{
  @include box-shadow(0 0 5px rgba(81, 203, 238, 1));
  -webkit-box-shadow: 0px 0px 5px #007eff;  
  -moz-box-shadow: 0px 0px 5px #007eff;  
  box-shadow: 0px 0px 5px #007eff;
}

下面是Bootstrap使用的代码。颜色略有不同,但概念相同。这是如果您使用LESS来编译CSS:

// Form control focus state
//
// Generate a customized focus state and for any input with the specified color,
// which defaults to the `@input-focus-border` variable.
//
// We highly encourage you to not customize the default value, but instead use
// this to tweak colors on an as-needed basis. This aesthetic change is based on
// WebKit's default styles, but applicable to a wider range of browsers. Its
// usability and accessibility should be taken into account with any change.
//
// Example usage: change the default blue border and shadow to white for better
// contrast against a dark gray background.

.form-control-focus(@color: @input-border-focus) {
  @color-rgba: rgba(red(@color), green(@color), blue(@color), .6);
  &:focus {
    border-color: @color;
    outline: 0;
    .box-shadow(~"inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px @{color-rgba}");
  }
}

如果您不使用LESS,则为编译后的版本:

.form-control:focus {
    border-color: #66afe9;
    outline: 0;
    -webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 8px rgba(102, 175, 233, 0.6);
    box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 8px rgba(102, 175, 233, 0.6);
}

这将创建发光的输入字段和文本区域:

textarea,textarea:focus,input,input:focus{
    transition: border-color 0.15s ease-in-out 0s, box-shadow 0.15s ease-in-out 0s;
    border: 1px solid #c4c4c4;
    border-radius: 4px;
    -moz-border-radius: 4px;
    -webkit-border-radius: 4px;
    box-shadow: 0px 0px 8px #d9d9d9;
    -moz-box-shadow: 0px 0px 8px #d9d9d9;
    -webkit-box-shadow: 0px 0px 8px #d9d9d9;
}

input:focus,textarea:focus { 
    outline: none;
    border: 1px solid #7bc1f7;
    box-shadow: 0px 0px 8px #7bc1f7;
    -moz-box-shadow: 0px 0px 8px #7bc1f7;
    -webkit-box-shadow: 0px 0px 8px #7bc1f7;
}
