如何調整flexslider的大小？

我正在使用以下模板來構建我的學校網站。 http://themes.quitenicestuff.com/parkcollegewp/如何調整flexslider的大小？

他們已經在他們的模板中使用了flex滑塊。但是我不需要全尺寸滑塊，而需要將滑塊的大小縮小到我的頭部大小。

這裏是flexslider.css

/* Browser Resets */ 
.flex-container a:active, 
.slider a:active, 
.flex-container a:focus, 
.slider a:focus {outline: none;} 
.slides, 
.flex-control-nav, 
.flex-direction-nav {margin: 0; padding: 0; list-style: none;} 

/* FlexSlider Necessary Styles 
*********************************/ 
.slider, .slider-blocks, .page-slider {padding: 0;} 
.slider .slides > li, .slider-blocks .slides > li, .page-slider .slides > li {display: none; -webkit-backface-visibility: hidden;} /* Hide the slides before the JS is loaded. Avoids image jumping */ 
.slider .slides img, .page-slider .slides img {width: 100%; display: block;} 
.flex-pauseplay span {text-transform: capitalize;} 

/* Clearfix for the .slides element */ 
.slides:after {content: "."; display: block; clear: both; visibility: hidden; line-height: 0; height: 0;} 
html[xmlns] .slides {display: block;} 
* html .slides {height: 1%;} 

/* No JavaScript Fallback */ 
/* If you are not using another script, such as Modernizr, make sure you 
* include js that eliminates this class on page load */ 
.no-js .slides > li:first-child {display: block;} 

/* FlexSlider Default Theme 
*********************************/ 
.slider, .slider-blocks, .page-slider { background: transparent; position: relative; zoom: 1;} 
.flex-viewport {max-height: 2000px; -webkit-transition: all 1s ease; -moz-transition: all 1s ease; transition: all 1s ease;} 
.slider .slides, .slider-blocks, .page-slider {zoom: 1;} 
.carousel li {margin-right: 5px} 

/* Direction Nav */ 
.flex-direction-nav {*height: 0;} 
.flex-direction-nav .flex-disabled {opacity: .3!important; filter:alpha(opacity=30); cursor: default;} 

/* Control Nav */ 
.flex-control-nav {width: 100%; text-align: center;} 
.flex-control-nav li {margin: 0 3px; display: inline-block; zoom: 1; *display: inline;} 
.flex-control-paging li a {width: 11px; height: 11px; display: block; background: #666; background: rgba(0,0,0,0.5); cursor: pointer; text-indent: -9999px; -webkit-border-radius: 20px; -moz-border-radius: 20px; -o-border-radius: 20px; border-radius: 20px; box-shadow: inset 0 0 3px rgba(0,0,0,0.3);} 
.flex-control-paging li a:hover { background: #333; background: rgba(0,0,0,0.7); } 
.flex-control-paging li a.flex-active { background: #000; background: rgba(0,0,0,0.9); cursor: default; } 

.flex-control-thumbs {margin: 5px 0 0; position: static; overflow: hidden;} 
.flex-control-thumbs li {width: 25%; float: left; margin: 0;} 
.flex-control-thumbs img {width: 100%; display: block; opacity: .7; cursor: pointer;} 
.flex-control-thumbs img:hover {opacity: 1;} 
.flex-control-thumbs .flex-active {opacity: 1; cursor: default;}

即使我改變寬度從100％到1000像素不change.What應該怎麼辦？請幫助我，我已經張貼它的WordPress論壇但沒有得到一個單一的答覆。謝謝
