Overview

Was a little challenging if getting used to JavaScript. BMI was a great warmup. Some css understanding of flexbox and grid. BMI using JS is operable. I chose *imperial instead of both.

The challenge

Users should be able to:

• Select whether they want to use metric or *imperial units
• Enter their height and weight
• See their BMI result, with their weight classification and healthy weight range
• 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
• CSS custom properties
• Flexbox
• CSS Grid
• Mobile-first workflow

What I learned

The JavaScript side of things. First time actually using conditionals:

if (bmi <= 18.4) { document.getElementById(‘message’).innerHTML = ‘You are under weight’ } else if (bmi >= 18.5 && bmi <= 24.9) { document.getElementById(‘message’).innerHTML = ‘You are at a healthy weight’ } else { document.getElementById(‘message’).innerHTML = ‘You are overweight’ }

Continued development
