Generally, details are used to further explain the content displayed on the page. The effect displayed is similar to that of the jQuery accordion plug-in.
It is roughly written as follows:
<details> <summary>Google Nexus 6</summary> <p>商品详情：</p> <dl> <dt>屏幕</dt> <dd>5.96” 2560x1440 QHD AMOLED display (493 ppi)</dd> <dt>电池</dt> <dd>3220 mAh</dd> <dt>相机</dt> <dd>13MP rear-facing with optical image stabilization 2MP front-facing</dd> <dt>处理器</dt> <dd>Qualcomm? Snapdragon? 805 processor</dd> </dl> </details>
The first is the . The content here is generally short and summary, and will be displayed on the page . You can then follow any type of HTML element as detailed content, which will only be displayed when
is clicked.
Details is a new interactive element in h5. Details can be used in conjunction with the summary tag to define a title for details. By default, the content in the details tag is not displayed. When the user clicks on the title, details are displayed. The emergence of the
details tag has brought us a better user experience. There is no need to write JS to achieve this shrinking and expanding effect.
details has a newly added sub-tag - summary. When the mouse clicks on the content text in the summary tag, all other elements in the details tag will expand or contract.
