styled componentsA couple nights ago I was working on a project that I m building in React Making sure I m referencing class names correctly and importing CSS files in the right places was something I ve done before This time none of my styles were applying and I d done all the troubleshooting I could So I hit up Google and look up styling in React Very broad search terms I know but it helped me find styled components What is styled components In short styled components allow you to write CSS in JS files I d never used styled components before and I only remembered hearing about it very briefly First I had to install the styled components package To do so I ran npm i styled componentsThen I got to work on my Footer js file The Footer component came out like this import Link from react router dom import styled from styled components const SiteFooter styled footer position fixed background color FBB bottom width const linkStyle margin rem textDecoration none color white function Footer return lt SiteFooter gt lt Link to contact style linkStyle gt Contact lt Link gt lt SiteFooter gt export default Footer And voila We have a footer By importing styled from the styled components package I am able to create a React component that will render the selected HTML element Let s say I wanted to make a div that is a red square Styled components allows me to reference the red square as a component that I might name RedSquare const RedSquare styled div width px height px background color red In SiteFooter you ll notice that the CSS is written inside of back ticks these are tagged template literals An easy way to think of tagged template literals is like a function Benefits of using styled componentsA footer was a great reason for using styled components because it requires minimal styling Since I ve handled all the styling in the component itself I don t have to search through files for the class name and make changes Styling markup and logic are all in one file and makes for a smooth developer experience This has been quite the unlock in my deep dive into React What are your favorite things about React |
