[Résolu] Fixer <figcaption>

Bonjour je teste le site http://www.templategarden.com/preview/ascend/ pour l'utiliser ensuite et au niveau du portfolio les balises <figcaption> ne s'affichent pas sur mobile alors pour simplifier j'aimerai les rendre fixe. Sauf que je n'y arrive pas.

Pourriez vous m'aider à y voir plus clair :

.grid figure {
	margin: 0;
	position: relative;
	border: 1px solid #ddd;
}
.grid figure img {
	width: 100%;
	display: block;
	position: relative;
	
}
.grid figcaption {
	position: absolute;
	top: 0;
	left: 0;
	padding: 20px;
	color: #fff;
	background-color: #34b1c4;
}
.grid figcaption h5 {
	margin: 0;
	padding-top: 0px;
	padding-left: 20px;
	padding-bottom: 5px;
	color: #fff;
	font-weight: 700;
	text-align: left;
	letter-spacing: 1px;
}
.grid figcaption a {
	text-align: left;
	padding: 5px 10px;
	margin-left: 20px;
	display: inline-block;
	background: #2f2f2f;
	color: #fff;
	font-size: 13px;
}
/* Caption Style */
.mask figure {
	overflow: hidden;
}
.mask figure img {
	-webkit-transition: -webkit-transform 0.4s;
	-moz-transition: -moz-transform 0.4s;
	transition: transform 0.4s;
}
.no-touch .mask figure:hover img, .mask figure.cs-hover img {
	-webkit-transform: translateY(-30px);
	-moz-transform: translateY(-30px);
	-ms-transform: translateY(-30px);
	transform: translateY(-30px);
}
.mask figcaption {
	height: 50px;
	width: 100%;
	top: auto;
	bottom: 0;
	opacity: 0;
	-webkit-transform: translateY(100%);
	-moz-transform: translateY(100%);
	-ms-transform: translateY(100%);
	transform: translateY(100%);
	-webkit-transition: -webkit-transform 0.4s, opacity 0.1s 0.3s;
	-moz-transition: -moz-transform 0.4s, opacity 0.1s 0.3s;
	transition: transform 0.4s, opacity 0.1s 0.3s;
}
.no-touch .mask figure:hover figcaption, .mask figure.cs-hover figcaption {
	opacity: 1;
	-webkit-transform: translateY(0px);
	-moz-transform: translateY(0px);
	-ms-transform: translateY(0px);
	transform: translateY(0px);
	-webkit-transition: -webkit-transform 0.4s, opacity 0.1s;
	-moz-transition: -moz-transform 0.4s, opacity 0.1s;
	transition: transform 0.4s, opacity 0.1s;
}
.mask figcaption a {
	position: absolute;
	top: 10px;
	bottom: 10px;
	right: 30px;
}

Merci beaucoup

J'ai supprimé tout le /* Caption Style */. A force de persévérer ca paye
