Question

I want to place a white border around the slider like this >> .

I tried using .coin-slider img { border: 2px solid white;} , but it didn’t work.

Coin-slider link >> Coin-slider official site

HTML:

<div id='coin-slider'>

                     <img src='images/slideshow1x.png' />
                            <span>
                                Description for img01
                            </span>



                     <img src='images/slideshow2x.jpg' />
                            <span>
                                Description for img01
                            </span>



                     <img src='images/slideshow3x.jpg' />
                            <span>
                                Description for img01
                            </span>



                     <img src='images/slideshow4x.jpg' />
                            <span>
                                Description for img01
                            </span>

</div>

CSS:

.coin-slider { overflow: hidden; zoom: 1; position: relative; }
.coin-slider img { border: 2px solid white;}
/*.coin-slider a{ text-decoration: none; outline: none; border: none; } */

.cs-buttons { font-size: 0px; padding: 10px; float: left; }
/*.cs-buttons a { margin-left: 5px; height: 10px; width: 10px; float: left; border: 1px solid #B8C4CF; color: #B8C4CF; text-indent: -1000px; }*/
.cs-active { background-color: #B8C4CF; color: #FFFFFF;}

.cs-title { width: 545px; padding: 10px; background-color: #000000; color: #FFFFFF; }

.cs-prev, 
.cs-next { background-color: #000000; color: #FFFFFF; padding: 0px 10px; }

In your HTML, coin-slider is the id of the div, and not class, whereas in your CSS you are referring to .coin-slider everywhere.

Change <div id='coin-slider'> to <div class='coin-slider'> in your HTML and everything should work fine.

Here is a demo.
