Мне не разрешено добавлять в JQuery/Javascript на этом сайте, поэтому я искал любой способ сделать кнопку «Вверх» и перевести ее на верхний уровень только с CSS/HTML ... don ' Думаю, что это возможно, но проверяя, не нашел ли кто-нибудь решение.Плавный прокрутка вверх страницы с CSS/HTML?
Он не будет гладким прокруткой, но вы можете использовать тег ахора для ссылки на любую часть страницы. Вот пример из школ W3.

<h2><a id="top">There is a link at the bottom of the page!</a></h2>
<p>In my younger and more vulnerable years my father gave me some advice that I've been turning over in my mind ever since.</p>
<p>"Whenever you feel like criticizing any one," he told me, "just remember that all the people in this world haven't had the advantages that you've had."</p>
<p>He didn't say any more, but we've always been unusually communicative in a reserved way, and I understood that he meant a great deal more than that. In consequence, I'm inclined to reserve all judgments, a habit that has opened up many curious natures to me and also made me the victim of not a few veteran bores. The abnormal mind is quick to detect and attach itself to this quality when it appears in a normal person, and so it came about that in college I was unjustly accused of being a politician, because I was privy to the secret griefs of wild, unknown men. Most of the confidences were unsought-frequently I have feigned sleep, preoccupation, or a hostile levity when I realized by some unmistakable sign that an intimate revelation was quivering on the horizon; for the intimate revelations of young men, or at least the terms in which they express them, are usually plagiaristic and marred by obvious suppressions. Reserving judgments is a matter of infinite hope. I am still a little afraid of missing something if I forget that, as my father snobbishly suggested, and I snobbishly repeat, a sense of the fundamental decencies is parcelled out unequally at birth.</p>
<p>And, after boasting this way of my tolerance, I come to the admission that it has a limit. Conduct may be founded on the hard rock or the wet marshes, but after a certain point I don't care what it's founded on. When I came back from the East last autumn I felt that I wanted the world to be in uniform and at a sort of moral attention forever; I wanted no more riotous excursions with privileged glimpses into the human heart. Only Gatsby, the man who gives his name to this book, was exempt from my reaction-Gatsby, who represented everything for which I have an unaffected scorn. If personality is an unbroken series of successful gestures, then there was something gorgeous about him, some heightened sensitivity to the promises of life, as if he were related to one of those intricate machines that register earthquakes ten thousand miles away. This responsiveness had nothing to do with that flabby impressionability which is dignified under the name of the "creative temperament"-it was an extraordinary gift for hope, a romantic readiness such as I have never found in any other person and which it is not likely I shall ever find again. No-Gatsby turned out all right at the end; it is what preyed on Gatsby, what foul dust floated in the wake of his dreams that temporarily closed out my interest in the abortive sorrows and short-winded elations of men.</p>

в основном HREF использует селектор CSS, чтобы решить, какой якорь, чтобы перейти к
UPDATE: Так что я нашел интересную ссылку на smooth scrolling думал, что я бы разместить его по этому вопросу.
Насколько я знаю, нет способа сделать плавный переход страницы, используя только CSS. Как указано в aaronman, вы можете использовать атрибут HTML id, чтобы помочь перейти в разные места на странице. Вы даете элемент идентификатор, который может быть все, что вы хотите
<h1 id="whatever">Jump to me</div>
Тогда где-то на странице, вы можете использовать якорь тег, чтобы иметь возможность перейти на это.
<a href="#whatever">Jump to "Jump to me"</a>
Это работает очень похоже на ориентации элемента в CSS. Вы нацеливаете его с помощью id, и href доставит вас туда. Это полезно для таких проектов, как оглавление. В случае, если вы делаете что-то вроде оглавления, и хотите показать, что вы прыгнули в раздел, вы можете использовать псевдокласс для :target, чтобы выполнить это. Here - очень простой пример.
Способ, которым вы можете сделать это, не имея элемента для перехода к нему, дает ahref of #. Это переместится прямо в начало страницы. Это почти как <html> страницы имеет id#.
Для того, чтобы перейти к началу страницы с помощью CSS, вы должны добавить какое-то триггер для изменения CSS. Который, AFAIK, возможен только через встроенные JavaScript-скрипты html или EventListeners в javascript.
Вы можете, однако, перейти к точке на странице с помощью привязки якорей (href=#the_id_of_an_element), но это негласно, но вместо этого мгновенно.
Теперь мне удалось получить примерно вид гладкой прокрутки вверху страницы, или, скорее, начало элемента, но с использованием только CSS, у этого есть некоторые непростые побочные эффекты. Хотя, я поделюсь кодом и посмотрю, помогает ли он кому-либо в начале или с любой другой проблемой.
/*
\t KNOWN ISSUES
\t
\t - requires constant user input.
\t Either through hover or buttonpress
\t \t -> If an element would be triggered, they cannot be untriggered. CSS is not made for this.
\t
\t - moves the page
\t Well, what did you expect? CSS visualises the page. You can only move
\t the page through the CSS by editing visual content and making the page smaller,
\t basically forcing the client to move the user.
\t \t -> this also means that elements below the element are shown in the view
\t \t -> it is VERY visible, especially if you look at the scrollbar
\t \t
\t - has a delay depending on where the user is at
\t The animation has to reach the position of the user, basically.
\t \t
\t At least it works on IE?
\t But honestly, just use javascript to scroll to. It's literally an one-liner

\t Settings for the transitions
\t

\t the top is shown again. This also causes the user to be moved upwards

\t After that animation, the page is restored in size.

\t settings though. Height - height of whatever is beneath it, but

\t \t Min-height here is the amount of spacing between the element and

\t \t page size, and NOT its contents or its parent.

\t \t Set to your div height. Unfortunately, animations from auto to
\t \t 0px are not supported (yet?), and there's no real good trick
\t \t as a placeholder for this one. You could mess around with
\t \t max-height, but remember that this can cause a delay in animation
\t \t and creates differences in speed that are hard to tweak or measure.
\t */
\t height: 1400px;

\t \t In order to move the page, you'll have to suppress the content
\t \t that will be shown outside of the element. Ergo, hide the overflow.
