How to customize a select element through CSS to achieve this dark style?

Here is a CSS-powered select menu; you can customize it as you need to:

label.custom-select {
    position: relative;
    display: inline-block;

}

.custom-select select {
    display: inline-block;
    padding: 4px 3px 3px 5px;
    margin: 0;
    font: inherit;
    outline:none; /* remove focus ring from Webkit */
    line-height: 1.2;
    background: #000;
    color:white;
    border:0;
}

/* Select arrow styling */
.custom-select:after {
    content: "▼";
    position: absolute;
    top: 0;
    right: 0;
    bottom: 0;
    font-size: 60%;
    line-height: 30px;
    padding: 0 7px;
    background: #000;
    color: white;
    pointer-events: none;
}

.no-pointer-events .custom-select:after {
    content: none;
}
<label class="custom-select">
    <select>
        <option>Sushi</option>
        <option>Blue cheese with crackers</option>
        <option>Steak</option>
        <option>Other</option>
    </select>
</label>

JSFiddle


Using the pointer-events:none; it will let you click through the arrow and will activate the select field, So the CSS would look like this for that element.

.custom-select:after {
    content: "▼";
    position: absolute;
    top: 0;
    right: 0;
    bottom: 0;
    font-size: 60%;
    line-height: 30px;
    padding: 0 7px;
    background: #000;
    color: white;
    pointer-events:none;
}
