carrousel, tamanho da imagem no CSS

AJUDA...

Segue exemplo de carrousel.

Feito em Jquery, CSS, e html.

1) O mesmo funciona, porém o CSS não tem opção para aumentar o tamanho da imagem, segue código:

 <section class="container-fluid parallax parallax_shadow">
 <div class="row">
 <div id="mn_clientes" class="col-lg-12 col-md-12 col-sm-6">
 <h4 class="text-left space_top10" style="">
 TExto do Carrousel
 </h4>
 <div class="row">
 <div class="carrousel_padrao">
 <ul class="carrousel_padrao__slides">
 <li class="item"><img src="../site/img.jpg"></li>
 <li class="item"><img src="../site/img.jpg"></li>
 <li class="item"><img src="../site/img.jpg"></li>
 </ul>
 <div class="carrousel_padrao__arrow carrousel_padrao__arrow--left space_top40">
 <span class="fa fa-arrow-left font_24px"></span>
 </div>
 <div class="carrousel_padrao__arrow carrousel_padrao__arrow--right space_top40">
 <span class="fa fa-arrow-right font_24px"></span>
 </div>
 </div>
 </div>
 </div>
 </div>
 </section>
<script>
 $(document).ready(function() {
 'use strict';

 slides.style.transform = 'translateX(' + posX + 'px)';

 if (_this2.options.reverse) {
 if (posX >= _this2.width - oneThird) {
 posX = _this2.width - oneThird * 2;
 }
 } else {
 if (Math.abs(posX) >= oneThird * 2) {
 posX = -oneThird;
 }
 }

 animate();
 }

 _carousel.init(options);

 return _carousel;

 window.onload = function() {

	CSS:

	 

.carrousel_padrao {

}

.carrousel_padrao__arrow {
 width: 30px;
 height: 30px;

 */
}

.carrousel_padrao__arrow--right {

 */
}

.carrousel_padrao__arrow--right:hover,
.carrousel_padrao__arrow--left:hover {

 transition: 1s ease;
 -webkit-transition: all 100ms ease-in;
 -webkit-transform: scale(1.5);

 -ms-transform: scale(1.5);
 -moz-transition: all 100ms ease-in;
 -moz-transform: scale(1.5);
 transition: all 100ms ease-in;
 transform: scale(1.5);
}

	Estou com problemas no CODIGO acima, na parte que está comentado no CSS.

	Tentei inserir aquele código para acertar o tamanho da mensagem, mas não vai....

	SUGESTÕES:::????

	Obrigado.
