Css – Changing the background color of a drop down list transparent in html

css

I'm trying to change the background color of a drop down list in HTML to transparent.

HTML

<select id="nname">
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

CSS

#nname {
    padding: 5px;
    color: #000;
    font-size: 12px;
    background: transparent;
    -webkit-appearance: none;

}

however, the background stays white and the text stays black. Any ideas?

Best Answer

You can actualy fake the transparency of option DOMElements with the following CSS:

CSS

option { 
    /* Whatever color  you want */
    background-color: #82caff;
}

See Demo

The option tag does not support rgba colors yet.

Javascript – Retrieve the position (X,Y) of an HTML element

The correct approach is to use element.getBoundingClientRect():

var rect = element.getBoundingClientRect();
console.log(rect.top, rect.right, rect.bottom, rect.left);

Internet Explorer has supported this since as long as you are likely to care about and it was finally standardized in CSSOM Views. All other browsers adopted it a long time ago.

Some browsers also return height and width properties, though this is non-standard. If you're worried about older browser compatibility, check this answer's revisions for an optimised degrading implementation.

The values returned by element.getBoundingClientRect() are relative to the viewport. If you need it relative to another element, simply subtract one rectangle from the other:

var bodyRect = document.body.getBoundingClientRect(),
    elemRect = element.getBoundingClientRect(),
    offset   = elemRect.top - bodyRect.top;

alert('Element is ' + offset + ' vertical pixels from <body>');

Either use a semi-transparent PNG or SVG image or use CSS:
