div内でdiv要素を作るにはどうすればいいですか？

Question

私の質問は、divスタイルの中にある要素= background-imageが画面が小さくなると正しく動作するようにする方法です。私の場合は、イメージボックス内の要素の1つが同じ高さを維持しているようです。

#main_article_box { 
 
    width: 728px; 
 
    height: 374px; 
 
    border: 1px solid #f8f8f8; 
 
    -moz-box-shadow: 0 2px 1px #9c9c9c; 
 
    -webkit-box-shadow: 0 2px 1px #9c9c9c; 
 
    box-shadow: 0 2px 1px #9c9c9c; 
 
} 
 
#main_article_text { 
 
    margin: 280px 3px 10px 3px; 
 
    height: 90px; 
 
    background: #ffffff; 
 
    border: 1px solid #f8f8f8; 
 
    background: #ffffff; 
 
    background: -moz-linear-gradient(#ffffff, #cccccc); 
 
    background: -webkit-gradient(linear, left bottom, left top, color-stop(0, #cccccc), color-stop(1, #ffffff)); 
 
    background: -webkit-linear-gradient(#ffffff, #cccccc); 
 
    background: -o-linear-gradient(#ffffff, #cccccc); 
 
    background: -ms-linear-gradient(#ffffff, #cccccc); 
 
    background: linear-gradient(#ffffff, #cccccc); 
 
    /*-moz-border-radius: 1px; 
 
\t border-radius: 1px; 
 
\t -moz-box-shadow: 0 1px 1px #f8f8f8; 
 
\t -webkit-box-shadow: 0 1px 1px #f8f8f8; 
 
\t box-shadow: 0 1px 1px #f8f8f8;*/ 
 
    opacity: 0.8; 
 
    filter: alpha(opacity=80); 
 
} 
 
#main_article_title { 
 
    font-size: 23px; 
 
    letter-spacing: -1px; 
 
    text-transform: uppercase; 
 
    text-shadow: #333; 
 
    font-weight: bold; 
 
    margin: 8px; 
 
} 
 
#main_article_short_text { 
 
    font-size: 14px; 
 
    width: 530px; 
 
    font-weight: bold; 
 
    margin: -2px 0 0 8px; 
 
    color: #333333; 
 
} 
 
@media only screen and (max-width: 460px) { 
 
    #main_article_box { 
 
    width: 100%; 
 
    height: auto; 
 
    } 
 
    #main_article_text { 
 
    width: 98%; 
 
    height: auto; 
 
    } 
 
    #main_article_title { 
 
    font-size: 16px; 
 
    } 
 
    #main_article_short_text { 
 
    font-size: 11px; 
 
    } 
 
}

<div id="main_article_box" style="background-image: url(http://www.watchathletics.com/data/headline/9718/rio%20usain%20bolt.jpg); no-repeat center; background-size: 100% auto; ">

私は、コードを理解するために、私だけのためにいくつかのスタイルを削除しました。この解決策はあなたに合っていますか？

.wrapper { 
 
    position:relative; 
 
    width:728px; 
 
    max-width:100%; 
 
} 
 
.wrapper:after { 
 
    content: ' '; 
 
    clear: both; 
 
    display: block; 
 
} 
 

 
#main_article_box {

    width:100%; 
 
    height:auto; 
 
    border:0 none;
