Button layout

How can I change the layout of the buttons?

In template_css.php from line 757:

/* read more buttons */

p.readmore a, p.mod-articles-category-readmore a, ul.pagenav a {
display: inline-block;
padding: 10px 15px;
line-height: 1;
color: #ffffff !important;
vertical-align: middle;
text-align: center;
cursor: pointer;
border: 0;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
-o-user-select: none;
user-select: none;
border-radius: 4px;
-webkit-border-radius: 4px;
-moz-border-radius: 4px;
border-radius: 4px;
background-color: #f96666;
background-image: none;
box-shadow: 0 -2px 1px #9f2f19 inset,0 2px 1px rgba(0,0,0,0.05);
text-shadow:none;
text-transform: uppercase;
font-weight: 300;
font-size: 14px;
}

p.readmore a:hover, p.mod-articles-category-readmore a:hover, ul.pagenav a:hover {
color: #ffffff !important;
-webkit-box-shadow: 0 2px 1px #9f2f19 inset;
-moz-box-shadow: 0 2px 1px #9f2f19 inset;
box-shadow: 0 2px 1px #9f2f19 inset;
background-position: inherit;
}

.content_sparky ul.pagenav {
margin: 0 !important;
padding: 40px 0 !important;
clear: both;
}
