Question

我有一个页面，https://adsler.co.uk/jobs/，但是当我尝试使用model.compile(optimizer='adam', loss='mse') model.fit(X, y, epochs=1) # prints out: Training None更改广告的背景颜色时，它不起作用。

尝试：

a href=

什么都没有。

我使用的是WordPress，页面由插件控制，因此难以编辑php / html，甚至找不到div类控制项，

您需要删除a和[href...]之间的空格。

ul.job_listings li.job_listing a[href="https://adsler.co.uk/job/nicos-cleaning-service-london-6-cleaner/"] {
  background-color: white;
}

ul.job_listings li.job_listing a:active[href="https://adsler.co.uk/job/nicos-cleaning-service-london-6-cleaner/"] {
  background-color: white;
}

body {
  background: black;
}

a {
  display: block;
}

<ul class="job_listings">
  <li class="post-7252 job_listing type-job_listing status-publish has-post-thumbnail hentry job-type-freelance" data-longitude="" data-latitude="" style="visibility: visible;">
    <a href="https://adsler.co.uk/job/nicos-cleaning-service-london-6-cleaner/">
      <h3>Cleaner</h3>
    </a>
  </li>
  <li class="post-6399 job_listing type-job_listing status-publish has-post-thumbnail hentry job-type-temporary" data-longitude="" data-latitude="" style="visibility: visible;">
    <a href="https://adsler.co.uk/job/nicos-cleaning-service-london-5-cleaners-needed/">
      <h3>Cleaners Needed</h3>
    </a>
  </li>
  <li class="post-6379 job_listing type-job_listing status-publish has-post-thumbnail hentry job-type-temporary" data-longitude="" data-latitude="" style="visibility: visible;">
    <a href="https://adsler.co.uk/job/customer-assistant/">
      <h3>Customer Assistant – Chelsea</h3>
    </a>
  </li>
  <li class="post-6169 job_listing type-job_listing status-expired has-post-thumbnail hentry job-type-freelance" data-longitude="" data-latitude="" style="visibility: visible;">
    <a href="https://adsler.co.uk/job/cleaner/">
      <h3>Cleaner</h3>
    </a>
  </li>
</ul>

图片中有CSS选择器。

您可以通过

只需将CSS应用于您的元素即可

a[href="https://adsler.co.uk/job/nicos-cleaning-service-london-6-cleaner/"]{
    /*your css properties*/
}

以下是一些参考供您

    Syntax:  [attribute^=value] 
    Example:  a[href^="https"]  
    Description:  Selects every <a> element whose href 
    attribute value begins with "https"

    Syntax:  [attribute$=value] 
    Example:  a[href$=".pdf"]   
    Description:  Selects every <a> element whose href 
    attribute value ends with ".pdf"

    Syntax:  [attribute*=value] 
    Example:  a[href*="someValue"]  
    Description:  Selects every <a> element whose href 
    attribute value contains the substring "someValue"'
