看到我codepen：http://codepen.io/Chiz/pen/ZOPvvZ大巨大的差距，當瀏覽器窗口大小調整到1100px以下
當調整瀏覽器的寬度窗口1100px或更少，有一個在英雄的旗幟底部的大缺口巨大和它下面的部分。
我相信這是由我在英雄橫幅上設置的700px的固定高度造成的。我嘗試將其設置爲height：auto，以便在瀏覽器窗口調整大小時自動計算高度，但不起作用。
任何想法？我試圖用CSS來做到這一點，而不是依賴bootstrap或grids/flexbox。

<p class="generic-center-text generic-content-text">Grace Patricia Kelly (November 12, 1929 – September 14, 1982) was an American actress who, after marrying Prince Rainier III in April 1956, became Princess of Monaco.<br /><br />After embarking on an acting career in 1950, at the age of 20, Kelly appeared in New York City theatrical productions and more than 40 episodes of live drama productions broadcast during the early 1950s Golden Age of Television. In October 1953, she gained stardom from her performance in the film Mogambo. </p>

<p class="generic-right-text generic-content-text">Tragedy struck on September 14, 1982, when Princess Grace and her younger daughter was driving along the steep cliffs of the Côte d'Azur region of southern France. She suffered a stroke and lost control of the vehicle, which spun off the cliff's edge and plunged down a 45-foot embankment. Mother and daughter were rushed to a hospital where Princess Grace spent 24 hours in a coma before passing away at the age of 52. Princess Stéphanie survived with minor injuries.<br /><br />
Grace Kelly remained in the public eye for most of her life. Her on-screen beauty, self-confidence and mystery enchanted the world, and her serenity and poise as Princess Consort piqued the media's attention. Of this attention, she remarked with typical humor and grace, "The freedom of the press works in such a way that there is not much freedom from it." Kelly's very public life is set to be portrayed by Nicole Kidman in the film Grace of Monaco (2014).</p>
