CSS打印寬度不適用

Question

我一直在嘗試簡單地使#content div在打印樣式表中為100％寬度。 無論我嘗試什么，我似乎都無法使它正常工作。

可以在此處看到視覺效果的屏幕截圖： http ： //t.co/brgvKPtKxA

標頭消息跨越100％，這很有趣，但僅此而已。

我的CSS看起來像：

@media print {

    html, body, #content { width: 100%; padding: 0; margin: 0; display: block; overflow: visible; padding-right: 30px; }
    @page { size: portrait; margin: 1cm; }
    nav, #search, footer, #breadcrumbs, #pull-search, #scroll-to-top, img, #aside { display: none; }

    h1 { font-size: 22pt; }
    h2 { font-size: 18pt; }
    h3 { font-size: 14pt; }
    p, ul, ol { font: 10pt/13pt Times New Roman, serif; }
    table { page-break-inside : avoid; }

    header:before {
        display: block;
        content: "Thank you for printing our content at www.schoolcraft.edu. Please check back often for news and updates.";
        border: 1px solid #bbb;
        font-style: italic;
        padding: 3px 5px;
        margin: 0 0 10px 0;
    }

} /* end of print query */

我的代碼有點混亂，因為我一直在每秒嘗試新事物。 我以前曾經遇到過這個問題，但是我從來沒有遇到過這樣的困惑。 有什么建議么？

感謝您的時間和幫助。

Answer 1

刪除這些：

style="width: 76%;"

style="width: 24%;"

並為div：s添加id：s（id =“ content_right”，id =“ content_left”），如下所示：

<section id="content">               
<div class="sf_cols">
    <div id="content_left" class="sf_colsOut sf_2cols_1_75">
        <div id="MainContent_Content_C004_Col00" class="sf_colsIn sf_2cols_1in_75" style="margin: 0px 70px 0px 0px; ">
            <div class='sfContentBlock'>
                <h1>Heading</h1> 
                <p>Maecenas laoreet bibendum nisi, vitae pharetra dolor. Sed id viverra enim, semper tincidunt magna. Curabitur varius nisl vel sapien commodo, id gravida ipsum elementum. Integer dui orci, malesuada eget hendrerit tempor, interdum vel tortor. Phasellus quis leo aliquet, feugiat turpis sed, egestas libero. Duis placerat hendrerit lacus in vulputate. Aliquam tristique, neque vel vehicula eleifend, urna erat imperdiet orci, id pulvinar tellus nisi in quam. Etiam a varius justo. Quisque consectetur commodo velit ac laoreet. Suspendisse aliquet vehicula urna. Vestibulum at justo non nibh placerat aliquet vel a arcu. Morbi at convallis ante. Vivamus in nulla quis mauris ornare tempus. Nam ultrices nisi quis nisi ullamcorper iaculis. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. Nulla facilisi.</p>
            </div>
        </div>
    </div>
    <div id="content_right" class="sf_colsOut sf_2cols_2_25">
        <div id="MainContent_Content_C004_Col01" class="sf_colsIn sf_2cols_2in_25" style="margin: 0px; ">            
        </div>
    </div>
</div>

然后將此添加到您的桌面 CSS：

#content_left {
  width: 76%;
}

#content_right {
  width: 24%;
}
