Assignment Details: - Developed for the freeCodeCamp React Project: Build a Markdown Previewer - Details: https://www.freecodecamp.com/challenges/build-a-markdown-previewer
Requirements for this assignment: - Objective: Build a CodePen.io app that is functionally similar to this: https://codepen.io/FreeCodeCamp/full/obYYqW. - Rule #1: Don't look at the example project's code. Figure it out for yourself. - Rule #2: Fulfill the below user stories. Use whichever libraries or APIs you need. Give it your own personal style. - Rule #3: You must use both Sass and React to build this project. - User Story: I can type GitHub-flavored Markdown into a text area. - User Story: I can see a preview of the output of my markdown that is updated as I type. - Hint: You don't need to interpret Markdown yourself - you can import the Marked library for this: https://cdnjs.com/libraries/marked
Assignment Completed. v1.0 03/28/2016: - Responsive design using HTML5, Font-Awesome, Sass, and React with JSX syntax - All required user stories fulfilled. - Added highlight.js support for nicer code-block styling
To Do: - emoji support -->
