Thank you.
To keep effects (hover) and have an one line button I modified a bit.
.blog-postcol a.button.blue.small {
visibility: hidden;
position: relative;
}
.blog-postcol a.button.blue.small::after {
visibility: visible;
position: absolute;
content: "Your text"!important;
color: white !important;
background: #03a9f4 !important;
top: 0px !important;
left: 0px !important;
padding: 13px 20px;
border-radius: 4px !important;
-moz-box-shadow: 0px 1px 2px 0px rgba(0, 0, 0, 0.14), 0 3px 1px -2px rgba(0, 0, 0, 0.2), 0 1px 5px 0 rgba(0, 0, 0, 0.12) !important;
