A big part of writing web applications is having a UI Kit to help create the interface of the application. We are going to use Bootstrap for our note taking app. While Bootstrap can be used directly with React; the preferred way is to use it with the React-Bootstrap package. This makes our markup a lot simpler to implement and understand.

Installing React Bootstrap

Run the following command in your working directory

$ npm install react-bootstrap --save

This installs the NPM package and adds the dependency to your package.json.

Add Bootstrap Styles

React Bootstrap uses the standard Bootstrap styles; so just add the following styles to your public/index.html.

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/latest/css/bootstrap.min.css">

We’ll also tweak the styles of the form fields so that the mobile browser does not zoom in on them on focus. We just need them to have a minimum font size of 16px to prevent the zoom.

To do that, let’s add the following to our src/index.css.

input.form-control {
  font-size: 16px;
input[type=file] {
  width: 100%;

We are also setting the width of the input type file to prevent the page on mobile from overflowing and adding a scrollbar.

Now if you head over to your browser, you might notice that the styles have shifted a bit. This is because Bootstrap includes Normalize.css to have a more consistent styles across browsers.

Next, we are going to create a few routes for our application and set up the React Router.
