to change font colour and size you have to use modulejaslideshow2.css about line 263
for example i put size 18px
.ja-slide-thumbs-mask, .ja-slidewrap-style2 .ja-slide-thumbs-handles {
font-size:18px;
height:80px !important;
margin:0;
position:absolute;
right:auto;
width:auto !important;
}
Front module text it not coming from description but from title On the blog – it is where you can do own description and easy change what you want to display and how. You don’t have to use read more button you can assign link from images you place. And you can assign class ( providing you write them in css ) to display how you want to display your text. What I posted above is how to change text display on the front page module…you need to go to your modulejaslideshow2.css
