Parent and child font elements, relating px to ems

I have been asked to convert px values to em values.

The parent element has a font-value of 1em = 16px.

If the child element is to be 20px, is that not 1.25em (in relation to the parent value)? 1.25 em is being scored incorrectly.

header {
  font-size: 1.8em;
}

.title {
  font-size: 1.625rem;
}

h1 {
  font-size: 5.625rem;
}

h2 {
  font-size: 3.3125em;
}

h3 {
  font-size; 1.25em;
}

        Lake Tahoe is one of the most breathtaking attractions located in California. It's home to a number of ski resorts, summer outdoor recreation, and tourist attractions. Snow and skiing are a significant part of the area's reputation.

So, in short, my math was correct, but the syntax of my code was not. I accidentally had a semi-colon where a colon needed to be. False alarm. Carry on. :-)

Hi,

An 'em' unit is a multiplayer by two.

Default px on most browsers is 16px, 16px is 1em.

2em of 16px is 32px (16*2 = 32)

If you have set your body tag to 20px as default, 1em will be 20px, and 2em will be 40px;

Check out this mozilla dev for more details.

What happens if you try 1.2em?
