Reading/Web/Desktop Improvements/Features/Header/zh

作为桌面版改进计划的一部分，我们正在引入一个新的头部.
 * 1) 此头部的第一次变更包括一个重新配置的徽标，该徽标的尺寸较小（但是，文字标志和标语的尺寸与Vector皮肤中的尺寸相同）.
 * 2) 稍后，我们将探索使头部“固定”——即当用户向下滚动页面时也可以访问. 这将使读者和编者可以访问重要功能，例如编辑整个页面或查看对话和历史记录页面，而无需他们一直滚动页面.

发布计划
我们于2020年5月开始向办公维基（Office Wiki）和测试维基部署第一次变更，并计划在接下来的几个月中继续使用我们的早期采用者维基. 有关更多详细信息，请参见我们的主功能页面.

功能描述及要求
The first iteration of the header consists of the new logo. The reconfiguration of the logo will allow us to provide future functionality such as the sticky header mentioned above, as well as easy access to the collapsible sidebar.

The approach we took was to separate the logo into three components - the logo itself, the wordmark (the stylized name of the wiki), and the tagline (the text that site beneath the logo, for example “the free encyclopedia” for Wikipedia). This allows increased flexibility when defining logos both for this project, as well as for future WMF and community initiatives.

Visually, the logos will appear in a horizontal layout, with the logo to the left, and the wordmark and tagline immediately to the right of it (see mockup below).

设计要求及准则
The current design will feature the logo in a different configuration, as can be seen below:

We will also be publishing detailed logo creation guidelines soon.

局限性
The new header and logo setup introduces different constraints than were seen before. In particular:


 * The new logos will be image tags. This means that caching will need to be taken into account when changing any logos - i.e. the updated logos might take a few days to propagate throughout a wiki.
 * The new logos will be served as SVGs. No PNG fallbacks will be available. This means that for browsers that do not have JavaScript, the logos will be displayed as text only.

用户测试
We performed prototype testing with editors on a variety of wikis. This test included the new version of the header. The majority of users reported positive to neutral experiences to the new header and logo configuration. However, about 18 of the 226 editors tested (about 8%) expressed concerns with the size of the logo. The main concern stated was that the new configuration of the logo would not be as prominent and memorable as the current configuration. We share some of these concerns and will continue gathering feedback once the change is live on some of the production wikis.

We also believe that any effect this might have will be lessened once a persistent (sticky) header is introduced. Our current plan for the persistent header is to include the full or partial version of the logo throughout the reading experience, in addition to access to other functionality.

That said, we have explored other ways of making the logo more prominent - including centering it in the middle of the header, as can be seen in this prototype. Based on the feedback received from the test wikis, we will determine whether this is a direction we want explore more in the future:

大量测试
As the current header changes are visual-only, we will not be performing any direct quantitative testing for this change. However, we will be monitoring important metrics such as account creation and pageview to note any overall effects.
