I'm trying to create a form that allows for calculation of metabolic rate.
There is an if,then statement related to gender (formula changes if female vs male)
I'd also like the result to be targeted to a specific part of the page (anchor). Ideally a new section can appear (maybe need to link a new page?) to provide further details
Below is my code, any help would be so appreciated!!
<head>
<style>
body {
font: 15px gothic, sans-serif;
letter-spacing: 1px;
}
input {
width: 100%;
}
input[type=number] {
border: none;
border-bottom: 1px solid grey;
}
input[type=button], input[type=submit], input[type=reset] {
background-color: #ddcecb;
border: none;
-moz-border-radius: 5px;
-webkit-border-radius: 5px;
color: #95483e;
padding: 16px 32px;
text-decoration: none;
letter-spacing: 1px;
margin: 4px 2px;
#submit:hover {
border: none;
background: #d2d1d1;
box-shadow: 0px 0px 1px #777;
}}
input[type=text]:focus {
border: 1px solid #555;
}
.form-inline label {
margin: 5px 10px 5px 0;
}
@media (max-width: 800px) {
.form-inline input {
margin: 10px 0;
}
.form-inline {
flex-direction: column;
align-items: stretch;
}
</style>
