Question

这段代码有什么问题？它适用于代码学院。我是html的新手，因此我仍在测试水域。我刚刚下载了括号，开始在代码学院之外做自己的事情，但这严重阻碍了我。这有什么不妥？每次我尝试预览时，Brackets都会抛出错误。它说：“确保有一个html文件或我在文件夹中有一个index.html文件。

    background-size: cover;
     background-color: #cccccc;
    }
h1{

    color: solid black;
    background-color: orange;
    }
th{
    background-color: red;
    font-size: 30px;
    border-bottom: 10px solid black;
    }

    border-right: 2px solid black;
    border-left:  2px solid black;
    border-top: 2px solid black;

    }

img{

    border-right: 5px solid black;
    border-left:  2px solid black;
    border-top: 2px solid black;

Answer 1

你到处都有语法错误，试试这个：

>>> local_tz = pytz.timezone('America/Chicago')
>>> local_time = local_tz.localize(datetime.datetime(2015, 8, 6, 0, 0))
>>> print local_time
2015-08-06 00:00:00-05:00
>>> utc_time = local_time.astimezone(pytz.utc)
>>> print utc_time
2015-08-06 05:00:00+00:00

同时更改

                             </tr>
                             <tr>
                                  <td><em>Hey!</em></td>
                                  <td><em>-yeah?</em></td>
                             </tr>
                             <tr>
                                  <td><em>do you care?</em></td>
                                  <td><em>-don't think so!</em></td>
                             </tr>
                      </table>
               </div>
          <p><em><strong>
          "Life is too short to be wasting time being stupid, enjoy what you have and live!"
