Question

function countSuccessPosts(rssFeeds) {
  var index, itemIndex, feed, item, successCounter = 0;

  for (index = 0; index < rssFeeds.length; index++) {
    feed = rssFeeds[index];

    for (itemIndex = 0; itemIndex < feed.itemsToPost.length; itemIndex++) {
      item = feed.itemsToPost[itemIndex];

      if(item.response && item.response.id) {
        successCounter++;
      }
    }
  }

  return successCounter;
}

以上是我的代码，其中第1行有4个div，第2行有3个div。我试图让div响应。为此，代码中提到了<!DOCTYPE html> <html lang="en-US"> <head> <title>Responsive</title> <style> .city { float: left; margin: 5px; padding: 15px; width: 100%; height: 300px; border: 1px solid black; } .city2 { float: left; margin: 5px; padding: 15px; width: 100%; height: 100px; border: 1px solid red; } </style> </head> <body background="page-bg.jpg"> <h1>W3Schools Demo</h1> <h2>Resize this responsive page!</h2> <div style="width:100%"> <div style="width:21%;" > <div class="city2"> <h2>London</h2> <p>London is the capital city of England.</p> </div> </div> <div style="width:21%;float:left;"> <div class="city2"> <h2>Paris</h2> </div> </div> <div style="width:21%;"> <div class="city2"> <h2>Tokyo</h2> </div> </div> <div style="width:21%;"> <div class="city2"> <h2>Istanbul</h2> </div> </div> </div> <div style="width:100%"> <div style="width:33.3%"> <div class="city"> <h2>London</h2> <p>London is the capital city of England.</p> <p>It is the most populous city in the United Kingdom, with a metropolitan area of over 13 million inhabitants.</p> </div> </div> <div style="width:33.3%"> <div class="city"> <h2>Paris</h2> <p>Paris is the capital and most populous city of France.</p> </div> </div> <div style="width:33.3%"> <div class="city"> <h2>Tokyo</h2> <p>Tokyo is the capital of Japan, the center of the Greater Tokyo Area, and the most populous metropolitan area in the world.</p> </div> </div> </div> </body> </html>的css。渲染代码时，前四个div不是直线。另外，当我调整窗口大小时，布置会响应，但这4个div前面有空白区域。很乐意帮助我如何使它们响应并占据屏幕各个方面的屏幕。

        .city {
