html - 我如何居中这个文字动画？

Question

总体上对文本动画和编码非常陌生 - 提前致歉!我目前正在尝试将整个文本动画集中在网站的标题部分。我一直在玩弄 css，但我很难让它看起来居中并保持水平并且在移动设备上看起来不错。任何建议或信息都会很棒 :) 非常感谢!

我叉了你的笔here .

我删除了大部分边距和填充，这就是我所拥有的(我评论了我在代码中所做的):

.rw-sentence {
  text-align: left;
  text-shadow: 1px 1px 1px rgba(255, 255, 255, 0.8);

  /* max-content make the width fit the content "at is largest" (without wrap) */
  /* this allow margin: 0 auto; to center it without white space 
     (It fit the box to the text and center the box) */
  width: max-content;
  margin: 0 auto;
  /* This is also necessary, otherwise you'd have to compensate for the difference
     in height with the container one way or another */
  height: 100%;
}

.rw-sentence span {
  color: #333;
  font-size: 200%;
  /* I fiddled to find the right line height to fit the height of the container */
  /* not sure that's "best practice" but it work :) */
  line-height: 140%;
  font-weight: 400;
 }

稍后阅读有关响应问题的信息。

html {
  /* define a root font-size */
  /* using unit like vw (a % of the width of the viewport 
     or vmax (a % of the largest between the height and width of the viewport
     can make your design more fluid as it will adjust with the device viewport */

  font-size: 16px;
}

/* I set this container font-size to "1 time the root font-size" 
   The font size in your span (200%) is 200% of this font-size here 
   If you use 'rem' for other length (like width, height ..) it will still
   be representing the root font-size (here x time 16px) */

.rw-sentence {
  font-size: 1rem;

/* This is the values I chose for the media queries but feel free to 
   play around with those values, trying 'vw', 'vmax', using rem ...*/
