کامپوننت media object در بوت استرپ 4 چیست و چه کاربردی دارد:

Media object ها، باکس هایی حاوی محتوای متن و تصویر می باشند، که معمولا به صورت افقی در صفحات قرار می گیرند. Media object ها می توانند در قالب نظرات و خلاصه ای از مقالات و... در صفحات دیده شوند.

 

Media object  ها دارای کلاس های زیر می باشند:

• Media : برای ایجاد media object استفاده می شود.
• Media-body : برای ایجاد محتوای اصلی media object استفاده می شود.
• Align-self-*(for image) : برای تنظیم کردن عکس در media object استفاده می شود.
• Nesting media : یکی از امکانات جالب این کامپوننت این است که می توان درون یک media  یک media دیگرهم قرار داد، به عبارتی به صورت تودرتو می توان استفاده کرد.
• Media list : برای ایجاد media object ها می توان از لیست ها <li><ul>,   استفاده کرد.

 

برای درک بهتر مطالب به مثال های زیر توجه کنید:

ساخت یک media object:

  <div class="media">
        <img class="mr-3" src="https://thr-storage.abramad.com:9021/images/../images/person/p1.webp?AWSAccessKeyId=zradfi8e9on5crea7roho17l7nj69btwwyh7fbfmnnji545u&Signature=IcM1ReKZ1Ssp16gISEHuLV0YcJM%3D&Expires=2148379697" alt="Generic placeholder image">
        <div class="media-body">
          <h5 class="mt-0">Media heading</h5>
          <span>Cras sit amet nibh libero, in gravida nulla. Nulla vel 
            metus scelerisque ante sollicitudin. Cras purus odio, vestibulum in vulputate at, tempus viverra turpis. Fusce condimentum 
            nunc ac nisi vulputate fringilla. Donec lacinia congue felis in faucibus.
