					bit of padding to be out of the way of the TabList.

					The button will toggle between full width (adding <code>width: 100%</code>) and the
					default width.
				</p>
				<p>Try the following:</p>
				<ul>
					<li>
						<strong>Small container</strong> that causes tabs to overflow with scroll.
					</li>
					<li>
						<strong>Large container</strong> that exceeds the normal width of the tabs.
						<ul>
							<li>
								<strong>
									With <code>width: 100%</code>
								</strong>{ ' ' }
								set on the TabList (tabs fill up the space).
							</li>
							<li>
								<strong>
									Without <code>width: 100%</code>
								</strong>{ ' ' }
								(defaults to <code>auto</code>) set on the TabList (tabs take up space proportional
								to their content).
