Title Hover Effect

Dear users: I tried to make a effect with the title. My intention was make the picture slide less opaque and the text appears, centred, over it at the same time when the cursor would be hover. I wrote a new code but the text-link doesn’t work because of the padding… Anyone could please help me? Thanks in advance!

.slideshow_container .slideshow_description_box { background: none; }

.slideshow_container .slideshow_description_box div.slideshow_title {
font-family: Arial,sans-serif;
font-size: 40px;
font-weight: 700;
letter-spacing: 0.5px;
text-transform: uppercase;
width: 100%;
height: 450px;
}
.slideshow_container .slideshow_description_box div.slideshow_description { }

.slideshow_container .slideshow_description_box div.slideshow_title a:link { padding-top: 200px !important; }

.slideshow_container .slideshow_transparent { }

.slideshow_container .slideshow_description_box div.slideshow_title { filter: alpha(opacity = 0); opacity: 0; }
.slideshow_container .slideshow_description_box div.slideshow_title:hover { filter: alpha(opacity = 100); opacity: 1; }
.slideshow_container .slideshow_slide_image { filter: alpha(opacity = 100); opacity: 1; }
.slideshow_container .slideshow_slide_image:hover  { filter: alpha(opacity = 50); opacity: 0.5; }
