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.


 * 1) The first iteration of this header includes a reconfigured logo, of a smaller size (however the wordmark and tagline remain the same size as they are currently in the Vector skin).
 * 1) Later on, we will explore making this header “sticky” - i.e. accessible when a user scrolls down the page. This will allow readers and editors to access important functionality such as editing the full page or viewing the talk and history pages, without requiring them to scroll all the way up the page.

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
标头的第一版变更包含新徽标. 徽标的重新配置将使我们能够提供将来的功能，例如上面提到的固定头部，以及易于访问的可折叠侧边栏.

我们采用的方法是将徽标分为三个部分——徽标本身、文字标记（维基的文字名称）和标语（徽标下方的文本，例如维基百科的“自由的百科全书”）. 在为该项目以及未来的WMF和社群计划定义徽标时，这可以提高灵活性.

徽标在视觉上将以水平布局显示，徽标在左侧，而文字标志和标语紧随其右侧（请参见下面的模型）.

设计要求及准则
当前的设计将以不同的配置显示徽标，如下所示：

我们还会在不久后发布详细的徽标创建准则.

限制
新的标题和徽标设置引入了与以前不同的限制. 特别是：


 * 新徽标将是图像标签. 这意味着在更改任何徽标时需要考虑缓存——即更新的徽标可能需要几天的时间才能传播到整个维基.
 * 新徽标将使用SVG. 没有可用的备用PNG提供. 这意味着对于没有JavaScript的浏览器，徽标将仅显示为文本.
 * 阅读详细的徽标配置指南.
 * 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.
 * Read detailed guidelines on configuring logos.

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:

定量测试
由于当前的头部更改仅是视觉上的，因此我们将不对该更改进行任何直接的定量测试. 但是，我们将监视重要的指标，例如帐户创建和综合浏览量，以记录所有总体影响.
