elements within the select element in CSS
EDIT 2015 May
Disclaimer: I've taken the snippet from the answer linked below:
In addition to WebKit, as of Firefox 35 we'll be able to use the appearance
property:
Using
-moz-appearance
with thenone
value on a combobox now remove the dropdown button
So now in order to hide the default styling, it's as easy as adding the following rules on our select element:
select {
-webkit-appearance: none;
-moz-appearance: none;
appearance: none;
}
For IE 11 support, you can use [::-ms-expand
][15].
select::-ms-expand { /* for IE 11 */
display: none;
}

Unfortunately what you ask is not possible by using pure CSS. However, here is something similar that you can choose as a work around. Check the live code below.
div {
margin: 10px;
padding: 10px;
border: 2px solid purple;
width: 200px;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;
}
div > ul { display: none; }
div:hover > ul {display: block; background: #f9f9f9; border-top: 1px solid purple;}
div:hover > ul > li { padding: 5px; border-bottom: 1px solid #4f4f4f;}
div:hover > ul > li:hover { background: white;}
div:hover > ul > li:hover > a { color: red; }
<div>
Select
<ul>
<li><a href="#">Item 1</a></li>
<li><a href="#">Item 2</a></li>
<li><a href="#">Item 3</a></li>
</ul>
</div>

Here is the question that you asked some time ago. How to style a <select> dropdown with CSS only without JavaScript? As it tells there, only in Chrome and to some extent in Firefox you can achieve what you want. Otherwise, unfortunately, there is no cross browser pure CSS solution for styling a select.
I've played around with select items before and without overriding the functionality with JavaScript, I don't think it's possible in Chrome. Whether you use a plugin or write your own code, CSS only is a no go for Chrome/Safari and as you said, Firefox is better at dealing with it.
There is no cross-browser way of styling option elements, certainly not to the extent of your second screenshot. You might be able to make them bold, and set the font-size, but that will be about it...
