Overview

The challenge

Users should be able to:

• View an age in years, months, and days after submitting a valid date through the form
• Receive validation errors if:
  • Any field is empty when the form is submitted
  • The day number is not between 1-31
  • The month number is not between 1-12
  • The year is in the future
  • The date is invalid e.g. 31/04/1991 (there are 30 days in April)
• View the optimal layout for the interface depending on their device's screen size
• See hover and focus states for all interactive elements on the page

My process

Built with

• Semantic HTML5 markup

• Flexbox
• CSS Grid
• Mobile-first workflow
• JS

What I learned

In this project I was able to develop skills with manipulating dates in Javascript, in addition to working with data validation and error handling.

The project requires dates to be checked against the maximum number of days, months and years. Thus, the validation included the use of the Date object, conditional structures, and DOM manipulation.

Continued development

Although the script is functional it can still be made cleaner. Thus, I intend to make changes to the code to make it cleaner and following good practice standards.

Code refactoring will have a positive impact, making the code lighter and more readable, in addition to facilitating future maintenance.
