I need to move the text shown in the slide component in order to center it.

Here is the site: <http://cmarosac-cp52.webjoomla.es/fav/>

The class is: flex-caption

```
.flex-caption {
width: 25%;
height: 96%;
padding: 2%; 
margin: 0; 
position: absolute; 
left: 0; 
bottom: 0; 
background: rgba(0,0,0,.3); 
color: #fff; 
text-shadow: 0 -1px 0 rgba(0,0,0,.3); 
font-size: 14px; 
line-height: 20px;
}

```

I would like to locate what is the path for the file where I use the class flex-caption.
