How to change the width of content slider?

please, reduce width of foo content id in custom-styles.css file inside your plugin folder.

#foo_content{

	padding: 9px;
	margin: 7px;
	display: block;
	float: left;
	height:auto;

	width:150px;
	min-height:150px;
	max-height:280px;

}

Also you can change image width and height in carousel-horizontal-posts-content-slider.php file line #7

@subhansanjaya- your solution doesn’t work. The poster is trying to change the width of the slider container and your solution changes the width of the slides.

The only way I found to do it was to override the inline styles.
In the CSS file I added:

.caroufredsel_wrapper{
width:923px !important;
}

Change that width to whatever you want. Remember to account for the arrows.
