Example/Picture of the Tw

Answer 1

This will create glowing input fields and textareas:

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;
}

Answer 2

Modified version with little less glowing version.

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;  
}

Answer 3

Use a normal blue border, a medium border-radius, and a blue box-shadow with position 0 0.

Answer 4

I combined two of the previous answers (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;  
}​

$('.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;
	left: 10px;
	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,
input,
.form-fild.open label,
.form-fild label {
	-webkit-transition: all 0.2s ease-in-out;
       -moz-transition: all 0.2s ease-in-out;
         -o-transition: all 0.2s ease-in-out;
            transition: all 0.2s ease-in-out;

Below is the code that Bootstrap uses. Colors are bit different but the concept is same. This is if you are using LESS to compile 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}");
  }
}

If you are not using LESS then here's the compiled version:

.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);
}
