Expenses chart component

In this challenge, you'll create a bar chart component from scratch. We provide a local JSON file, so you can add the chart data dynamically if you choose.


Your challenge is to build out this bar chart component and get it looking as close to the design as possible.

You can use any tools you like to help you complete the challenge. So if you've got something you'd like to practice, feel free to give it a go.

We provide the data for the chart in a local data.json file. So you can use that to add the bars dynamically if you choose.

Your users should be able to:

  • View the bar chart and hover over the individual bars to see the correct amounts for each day
  • See the current day's bar highlighted in a different colour to the other bars
  • View the optimal layout for the content depending on their device's screen size
  • See hover states for all interactive elements on the page
  • Bonus: See dynamically generated bars based on the data provided in the local JSON file

Download the project and go through the file. This will provide further details about the project and help you set it up.

🗃Assets provided

  • Sketch and Figma design file access - Unlock with Pro
  • JPEG design files for mobile & desktop layouts
  • Style guide for fonts, colors, etc.
  • Optimized image assets
  • README file to help you get started
  • HTML file with pre-written content

💡Ideas to test yourself

  1. Write your styles using a pre-processor, such as Sass, Less or Stylus

  2. Train your eye for detail by getting your solution as close to the design as you can

  3. Use a JavaScript framework/library to practice building using components

  4. Try estimating the time it will take for you to build the project. Then see if the time taken matches up to your estimate. Project estimations are a skill that is often overlooked but is essential for professional developers

Challenge FAQs

Can I use libraries/frameworks on these projects?

Yes! Our challenges provide professional designs but there are no rules on what tools to use. So feel free to use anything you like to build your projects.

How can I get help if I'm stuck on a challenge?

The best (and quickest) way to get help on a challenge is in our Slack community. There are thousands of other developers in there, so it's a great place to ask questions. We even have a dedicated "help" channel! If you haven't joined yet, you can get an invite to our Slack community here.

Can I use these projects in my portfolio?

Definitely! Please do feel free to use whatever you build in your portfolio. Helping developers add professional-looking projects to their portfolio was one of the reasons we created this platform!

Is there an official solution I can take a look at?

We don't provide "official" solutions for the challenges. This is because there is no single perfect way to complete a challenge. Instead, you're encouraged to review other people's code in the community. You can learn so much by seeing how other people have approached the same challenges and giving them feedback.

Do I get a code review when I post my solution?

Frontend Mentor is a collaborative learning community where everyone can give feedback to each other. If you'd like to receive feedback from the community, please be sure to post a question when you submit your solution. The more specific you can be, the better. Being clear with your questions means you're much more likely to receive valuable feedback from others.

How do I submit my solution?

We'd recommend reading our complete guide to submitting solutions . If you get stuck and need help, please feel free to ask questions in our Slack community, and we'll help you submit your project.

Can I use these challenges within my own free or commercial content/tutorials/projects?

Please visit our License page to learn more about how our challenges can be used within your own content. If you're unsure about anything, please feel free to contact us at [email protected] and we'll be more than happy to answer your questions.

How often are new challenges added?

We launch a new challenge every two weeks. We alternate between free and premium challenge launches, so we launch one free and one premium challenge each month.
