        As spawning season approaches, the fish acquire a humpback and protuberant jaw. After spawning, they die and their carcasses provide a feast for gatherings of mink, bears, and Bald eagles.

Look at this code example :

<body>   <!-- Consider that its font-size is set to 1.5em -->
     <h1>Header</h1>    <!-- Consider that its font-size is set to 2em -->

    <p>A paragraph explains smthng...</p>   <!-- Consider that its font-size is set to 1,5em --> 
</body>

to find font-size of the <p>tags, multiply its own size property with its parent elements font-size.

<p> tags have 1,5em, its parent <body> has 1.5em ; font-size of <p> : 1,5em*(1,5em) = 2,25em (36 pixels)

for <h1>

<h1> has 2 em, its parent <body> has 1,5em ; font-size of <h1> : 2em*(1,5em) = 3em (48 pixels)

Try to convert px units to em's. Challenge wants you to do that

Hi Seketha,

Oddly, the problem is with the precision of your font-size. The system rejects 1.250 but 1.25 passes the challenge.

Cheers
