How to change the underline color of the input component in MD Bootstrap

Question

So I'm using the Input Group Component from MDBootstrap.

I was wondering if there's a way around for changing the color of the blank of the input field component in MD Bootstrap. Like at the moment, it looks like this (without focus):

When I click on this input field, it looks like this (with focus, the color of the input field blank changes to green):

The code for the this component is as follows:

<div class="input-group input-group-lg">
  <div class="input-group-prepend">
    <span class="input-group-text" id="inputGroup-sizing-lg">Name</span>
  </div>
  <input type="text" class="form-control" aria-label="Large" aria-describedby="inputGroup-sizing-sm">
</div>

I was wondering if there's a way around for changing the color of the input field blank to black instead of green when we click on it. Thanks!

Set backgroundImage style with <input /> would work

Try it in-text:

 const style = { backgroundImage: `linear-gradient(0deg, black 2px, rgba(0, 150, 136, 0) 0), linear-gradient(0deg, rgba(0, 0, 0, 0.26) 1px, transparent 0)` }; const App = () => { return ( <div className="App"> <div class="input-group input-group-lg"> <div class="input-group-prepend"> <span class="input-group-text" id="inputGroup-sizing-lg"> Large </span> </div> <input type="text" class="form-control" aria-label="Large" style={style} aria-describedby="inputGroup-sizing-sm" /> </div> </div> ); }; ReactDOM.render(<App />, document.getElementById("root"));

 <div id="root"></div> <script src="https://cdnjs.cloudflare.com/ajax/libs/react/16.12.0/umd/react.production.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/react-dom/16.12.0/umd/react-dom.production.min.js"></script> <link rel="stylesheet" href="https://unpkg.com/bootstrap-material-design@4.1.1/dist/css/bootstrap-material-design.min.css" integrity="sha384-wXznGJNEXNG1NFsbm0ugrLFMQPWswR3lds2VeinahP8N0zJw9VWSopbjv2x7WCvX" crossorigin="anonymous" />

The step to achieve it:

If you check the style in the browser,

You would find that color with animation, copy it and change that color, and that's it.

You can change the border bottom:

.md-form .form-control#form1 {
  border-bottom: 1px solid #f48fb1;
}
