Unordered list has o height

hello can anybody tell me why my ul has 0 height although it has list items inside it? this is the php file with the unordered list

<div class="main-content">
        <ul class="products-list">
            <?php 
                foreach($catalog as $id => $item){
                     echo getItemHtml($id,$item);
                }
             ?>
        </ul>
    </div>

AND HERE IS THE CSS

.products-list {
    padding: 0;
    margin-top: 300px;
    width: 100%;
}
