<h5>Here's What We're Doing</h5>
<p class="beginning">The most important thing in sailing is experience. Read all the books you want - you'll still need time on the water.</p>
<p>The Down Champlain Regatta is a non-profit organization designed to give students, if nothing else, tons of time on the water. Its three weeks of all-weather keelboat sailing on Lake Champlain, something not offered in many other places, will teach students more than anything else can.</p>
<p>This course is not for new sailors. It's for kids who know how to sail, but want to take it to the next level. It's for kids who want to move up into the world of keelboat racing.</p>
<p>And at the end of the course, they do just that. The course finishes with an all-day, student-led race down Lake Champlain. This is a unique opportunity for the students to apply their newly learned skills, build confidence, and </p>

我想让页面在单击 #down 时向下滚动 100vh。我已经做了一些研究，但没有给我一个正确的答案。有没有办法使用 vh，或者我是否必须滚动到我想要的元素（#container）？
我建议滚动到#container，但也许window.innerHeight会有帮助。
要滚动到#container，您可以尝试类似的操作：
HTML 按钮：
<a href="#container">Check it out</a>
JS
$(document)
.on('click', 'a[href^="#"]', function(e) {
e.preventDefault();
var target = $(this).attr('href');
$('html, body')
.animate({
scrollTop: $(target).offset().top}, 'slow', 'swing', function() {});
})
