CSS/HTML: 在输入框周围创建一个发光的边框

我想为我的形式创建一些像样的输入,我真的很想知道如何 TWITTER 做他们的输入周围发光的边界。

例如/图片的 Twitter 边界:

我也不知道如何创建圆角。

使用一个正常的蓝色 border,一个中等 border-radius和一个蓝色 box-shadow与位置 0 0

SLaks 一针见血,但是您可能需要查看 CSS3中输入的更改。圆角和盒子阴影都是 CSS3中的新特性,可以让你做你想要的。我个人最喜欢的 CSS3/HTML5链接之一是 http://diveintohtml5.ep.io/

这个怎么样... http://jsfiddle.net/UnsungHero97/Qwpq4/1207/

enter image description here

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 */


}

给你:

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


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

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;
}
<label> Aktuelles Passwort: <input type="password"> </label>
<label> Neues Passwort: <input type="password"> </label>

我综合了前面两个答案(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;
}​

你最好使用 Bootstrap,它包含了所有这些美好的东西,特别是 给你正是你想要的。

此外,您可以使用从 本网站Bootstrap构建的不同主题

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。颜色有点不同,但概念是一样的。这是如果你使用较少的编译 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}");
}
}

如果你没有使用更少,那么这里是编译后的版本:

.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;
}

修改版本与少发光版本。

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;
}

$('.form-fild input,.form-fild textarea').focus(function() {
$(this).parent().addClass('open');
});


$('.form-fild input,.form-fild textarea').blur(function() {
$(this).parent().removeClass('open');
});
.open {
color:red;
}
.form-fild {
position: relative;
margin: 30px 0;
}
.form-fild label {
position: absolute;
top: 5px;

padding:5px;
}


.form-fild.open label {
top: -25px;
left: 10px;
/*background: #ffffff;*/
}
.form-fild input[type="text"] {
padding-left: 80px;
}
.form-fild textarea {
padding-left: 80px;
}
.form-fild.open textarea,
.form-fild.open input[type="text"] {
padding-left: 10px;
}
textarea,
input[type="text"] {
padding: 10px;
width: 100%;
}
textarea,
