How to create a line input effect?

Hi please can you advise onhow to create this line input effect , thanks

.form-textbox {
background: transparent !important;
outline-style: none !important;
border-top: none !important;
border-left: none !important;
border-right: none !important;
border-bottom: solid #000000 1px;
box-shadow: 0 0 0 !important;
-webkit-box-shadow: 0 0 0 !important;
}
