css - How to style the input type "time"

Question

I'm trying to find a source explaining how to fully style the input type "time". I cannot find a single example explaining all of the style attributes!

Only one I've found is:

input[type="time"]{
    /**style goes here **/
}

Which doesn't help much..

Tried this:

input[type="time"]::-webkit-inner-spin-button { 
    -webkit-appearance: none;
    cursor:pointer;
    display: block;
    width:20px;
    color: red;
    text-align:center;
    position:relative;
} 

Spinner does not turn red for example.

Answer 1

I made some progress styling the input in Chrome/webkit, but I can't figure out how to style anything in Firefox. Here's a demo that I put together on Codepen.

input[type=time] {
  border: none;
  color: #2a2c2d;
  font-size: 14px;
  font-family: helvetica;
  width: 180px;
}

/* Wrapper around the hour, minute, second, and am/pm fields as well as 
the up and down buttons and the 'X' button */
input[type=time]::-webkit-datetime-edit-fields-wrapper {
  display: flex;
}

/* The space between the fields - between hour and minute, the minute and 
second, second and am/pm */
input[type=time]::-webkit-datetime-edit-text {
  padding: 19px 4px;
}

/* The naming convention for the hour, minute, second, and am/pm field is
`-webkit-datetime-edit-{field}-field` */

/* Hour */
input[type=time]::-webkit-datetime-edit-hour-field {
  background-color: #f2f4f5;
  border-radius: 15%;
  padding: 19px 13px;
}

/* Minute */
input[type=time]::-webkit-datetime-edit-minute-field {
  background-color: #f2f4f5;
  border-radius: 15%;
  padding: 19px 13px;
}

/* AM/PM */
input[type=time]::-webkit-datetime-edit-ampm-field {
  background-color: #7155d3;
  border-radius: 15%;
  color: #fff;
  padding: 19px 13px;
}

/* 'X' button for resetting/clearing time */
input[type=time]::-webkit-clear-button {
  display: none;
}

/* Up/Down arrows for incrementing/decrementing the value */
input[type=time]::-webkit-inner-spin-button {
  display: none;
}

<input type="time" value="13:30"/>
