# Creating Components

A Polymer component consists of the structure, visual appearance and behavior. The name must contain a hyphen (-) for the browser to know it is a custom element. The structure is denoted by the template-tag. The appearance is added using a style tag. Behavior is placed outside the template within script-tag.

<my-element id="my">
	<template>
		<style>

		</style>
		<script>

		</script>
	</template>
</my-element>
