Re: Eileen Dover university application

Dear Eileen,

Thank you for your recent application to join us at the University of
Awesome's science faculty to study as part of your
PhD (Doctor of Philosophy) next year. I will answer your
questions one by one, in the following sections.

Starting dates

We are happy to accommodate you starting your study with us at any time,
however it would suit us better if you could start at the beginning of a
semester; the start dates for each one are as follows:

First semester: 9 September 2016
Second semester: 15 January 2017
Third semester: 2 May 2017

Please let me know if this is ok, and if so which start date you would
prefer.

Subjects of study

At the Awesome Science Faculty, we have a pretty open-minded research
facility — as long as the subjects fall somewhere in the realm of science
and technology. You seem like an intelligent, dedicated researcher, and
just the kind of person we'd like to have on our team. Saying that, of the
ideas you submitted we were most intrigued by are as follows, in order of
priority:

Turning H2O into wine, and the health benefits of Resveratrol
(C14H12O3.)
Measuring the effect on performance of funk bass players at temperatures
exceeding 30°C (86°F), when the audience size exponentially increases
(effect of 3 × 103 increasing to 3 × 104.)
HTML, Hypertext Markup Language, and CSS,
Cascading Style Sheets, constructs for representing musical scores.

So please can you provide more information on each of these subjects,
including how long you'd expect the research to take, required staff and
other resources, and anything else you think we'd need to know? Thanks.

Exotic dance moves

Yes, you are right! As part of my post-doctorate work, I
did study exotic tribal dances. To answer your question, my
favorite dances are as follows, with definitions:

Polynesian chicken dance
    A little known but very influential dance dating back as far as
    300 BCE, a whole village would
    dance around in a circle like chickens, to encourage their livestock to
    be "fruitful".
Icelandic brownian shuffle
    Before the Icelanders developed fire as a means of getting warm, they
    used to practice this dance, which involved huddling close together in a
    circle on the floor, and shuffling their bodies around in imperceptibly
    tiny, very rapid movements. One of my fellow students used to say that
    he thought this dance inspired modern styles such as Twerking.
Arctic robot dance
    An interesting example of historic misinformation, English explorers in
    the 1960s believed to have discovered a new dance style characterized by
    "robotic", stilted movements, being practiced by inhabitants of Northern
    Alaska and Canada. Later on however it was discovered that they were
    just moving like this because they were really cold.

Yours sincerely,

Dr Eleanor Gaye

项目简介

在此项目中，您的任务是标记一封需要托管在大学内网的信件。这封信是一位研究员回复一名潜在的博士生关于他们申请该大学事宜的信。

块/结构语义

添加适当的 HTML 结构，包括 doctype、<html>、<head> 和 <body> 元素。
通常，除了下一项中提到的地址外，这封信应标记为由标题和段落组成。有一个顶级标题（“Re:”行）和三个二级标题。
将两个地址放入 <address> 元素中。地址的每一行都应显示在新行上，但不在新段落中。
使用适当的列表类型来标记学期开始日期、研究课题和异国舞蹈。

行内语义

发件人和收件人的姓名（以及电话和电子邮件）应标记为具有强烈重要性。
文档中的四个日期应包装在包含机器可读日期的适当元素中。
信件中的第一个地址和第一个日期应设置 sender-column 类属性值。稍后添加的 CSS 将使它们右对齐，就像经典信件布局一样。
在信件正文中标记以下五个缩写词/缩略词——“PhD”、“HTML”、“CSS”、“BC”和“Esq.”—以提供它们的扩展。
应适当标记六个下标/上标——化学式中的下标/上标，以及数字 103 和 104（它们应该分别是 10 的 3 次方和 4 次方）。
在文本中标记至少两个其他适当的词语，以表示强烈重要性/强调。
用适当的元素标记大学座右铭引文和出处。

文档的 head 部分

文档的字符集应使用适当的 <meta> 标签设置为 utf-8。
信件的作者应在适当的 <meta> 标签中指定。
您应将文档的语言设置为 en-US。
在文档标题元素中包含以下文本：“Awesome science application correspondence”。

以下 CSS 应包含在 head 中适当的元素内

css

body {
  font: 1.2em / 1.5 system-ui;
}

.sender-column {
  text-align: right;
}

h1 {
  font-size: 1.5em;
}

h2 {
  font-size: 1.3em;
}

提示和技巧

使用 W3C HTML 验证器来验证您的 HTML。如果验证通过，请给自己额外的奖励分数。
您不需要了解任何 CSS 即可完成此作业。您只需要将提供的 CSS 放入 HTML 元素中。

示例

以下实时示例显示了标记后的信件应有的外观。如果您在如何实现其中一些功能时遇到困难，请参阅实时示例下方的解决方案。

您完成的 HTML 应该看起来像这样

html

<!doctype html>
<html lang="en-US">
  <head>
    <meta charset="utf-8" />
    <meta name="author" content="Dr. Eleanor Gaye" />
    <title>Awesome science application correspondence</title>
    <style>
      body {
        font: 1.2em / 1.5 system-ui;
      }

      .sender-column {

      }

      h1 {
        font-size: 1.5em;
      }

      h2 {
        font-size: 1.3em;
      }
    </style>
