CSS Transparent buttons with borders

Question

I am trying to make a button in css like this one

but I have no idea how to do it as I am new to css. This is what I tried:

.gbtnHollow  {
     background:  transparent;
     height:  38px;
     line-height:  40px;
     border:  2px solid white;
     display:  inline-block;
     float:  none;
     text-align:  center;
     width:  120px;
     padding:  0px!important;
     font-size:  14px;
     color:  #fff;
 }

.gbtnHollow:hover  {
     color:  #fff;
     background:  rgba(255, 255, 255, 0.2);
 }

Answer 1

It's very simple, set background: none; to button. JSFiddle

Answer 2

button {
    background-color: Transparent;
    background-repeat:no-repeat;
    cursor:pointer;
    overflow: hidden;
    outline:none;
}

Add this and customize it for you. Example is here on Fiddle
