媒體對象（Media object）

Bootstrap媒體對象的文檔和示例，用于構建高度重復的組件，如博客評論、推文等。

一、Example

媒體對象有助于構建復雜和重復的組件，其中一些媒體與不圍繞所述媒體的內容放在一起。此外，由于flexbox，它只需要兩個必需的類就可以做到這一點。

下面是一個單一媒體對象的示例。只需要兩個類——內容周圍的.media和.media-body 正文。可選的填充和邊距可以通過間距實用程序進行控制。

<!--Example-->
<div class="media"><img src="../images/2.jpg" class="mr-3" alt="..."><div class="media-body"><h5 class="mt-0">Media heading</h5><p>Will you do the same for me? It's time to face the music I'm no longer your muse. Heard it's beautiful, be the judge and my girls gonna take a vote. I can feel a phoenix inside of me. Heaven is jealous of our love, angels are crying from up above. Yeah, you take me to utopia.</p></div>
</div>

二、Nesting 嵌套

媒體對象可以無限嵌套，但我們建議您在某個時候停止。將嵌套的.media放入父媒體對象的.media-body 正文中。

<!--嵌套 Nesting-->
<div class="media"><img src="../images/a1.jpg" class="mr-3" alt="..."><div class="media-body"><h5 class="mt-0">Media heading</h5><p>Standing on the frontline when the bombs start to fall. Heaven is jealous of our love, angels are crying from up above. Can't replace you with a million rings. Boy, when you're with me I'll give you a taste. There’s no going back. Before you met me I was alright but things were kinda heavy. Heavy is the head that wears the crown.</p><div class="media mt-3"><a class="mr-3" href="#"><img src="../images/1.jpg" class="mr-3" alt="..."></a><div class="media-body"><h5 class="mt-0">Media heading</h5><p>Greetings loved ones let's take a journey. Yes, we make angels cry, raining down on earth from up above. Give you something good to celebrate. I used to bite my tongue and hold my breath. I'm ma get your heart racing in my skin-tight jeans. As I march alone to a different beat. Summer after high school when we first met. You're so hypnotizing, could you be the devil? Could you be an angel? It's time to bring out the big balloons. Thought that I was the exception. Bikinis, zucchinis, Martinis, no weenies.</p></div></div></div>
</div>

三、Alignment 對齊

媒體對象中的媒體可以與flexbox實用程序對齊到.Media-body 正文內容的頂部（默認）、中間或末尾。

• 頂部（默認）對齊方式：

<div class="media"><img src="..." class="align-self-start mr-3" alt="..."><div class="media-body"><h5 class="mt-0">Top-aligned media</h5><p>I’m gon’ put her in a coma. You give a hundred reasons why, and you say you're really gonna try. So I sat quietly, agreed politely. Suiting up for my crowning battle. And on my 18th Birthday we got matching tattoos. So très chic, yeah, she's a classic. I am ready for the road less traveled.</p><p>I'm walking on air (tonight). But down to earth. You're original, cannot be replaced. But in another life I would be your girl. We drove to Cali and got drunk on the beach. We can dance, until we die, you and I, will be young forever. Saw you downtown singing the Blues.</p></div>

• 中間對齊方式：

<div class="media"><img src="..." class="align-self-center mr-3" alt="..."><div class="media-body"><h5 class="mt-0">Center-aligned media</h5><p>She'll turn cold as a freezer. At the eh-end of it all. Stinging like a bee I earned my stripes. Bikinis, zucchinis, Martinis, no weenies. I hope you got a healthy appetite. We can dance, until we die, you and I, will be young forever. We're living the life. We're doing it right. Word on the street, you got somethin' to show me, me.</p><p class="mb-0">Wanna see the show in 3D, a movie. They say, be afraid you're not like the others, futuristic lover. Open up your heart. So I sat quietly, agreed politely. Last Friday night. Yeah, you're lucky if you're on her plane. I'll be your gift, give you something good to celebrate.</p></div>

• 末尾對齊方式：

<div class="media"><img src="..." class="align-self-end mr-3" alt="..."><div class="media-body"><h5 class="mt-0">Bottom-aligned media</h5><p>Come on, let your colours burst. I can feel this light that's inside of me. All night they're playing, your song. From Tokyo to Mexico, to Rio. There’s no going back. But down to earth. Magical, colorful, Mr. Mystery, ee. Different DNA, they don't understand you.</p><p class="mb-0">But down to earth. She's got that, je ne sais quoi, you know it. I can see the writing on the wall. The boys break their necks try'na to creep a little sneak peek. Take me, ta-ta-take me. Open up your heart. Thought that I was the exception. Boom, boom, boom. Venice beach and Palm Springs, summertime is everything. Bring the beat back. (This is how we do)</p></div>
</div>

四、Order 順序

通過修改HTML本身或添加一些自定義的flexbox CSS來設置order屬性（為您選擇的整數），從而更改媒體對象中內容的順序。

<!--Order-->
<div class="media"><div class="media-body"><h5 class="mt-0 mb-1">Media object</h5><p>I know there will be sacrifice but that's the price. Are you brave enough to let me see your peacock? Be your teenage dream tonight. Uh-huh, I see you. There’s no going back. Yeah, we maxed our credit cards and got kicked out of the bar. So let me get you in your birthday suit. You may fall in love when you meet her. Had the world in the palm of your hands. Don't let the greatness get you down, oh, oh yeah. Now we talking astrology, getting our nails did, all Japanese-y. Make me your Aphrodite.</p></div><img src="../images/2.jpg" class="ml-3" alt="...">

五、Media list 媒體列表

因為媒體對象的結構要求很少，所以您也可以在列表HTML元素上使用這些類。在您的<ul>或<ol>上，添加未設置樣式的.list-unstyled 以刪除任何瀏覽器默認列表樣式，然后將.media應用于您的<li>s。與往常一樣，在需要微調的地方使用間距實用程序。

<!--Media list-->
<ul class="list-unstyled"><li class="media"><img src="../images/2.jpg" class="mr-3" alt="..."><div class="media-body"><h5 class="mt-0 mb-1">List-based media object</h5><p>All my girls vintage Chanel baby. So you can have your cake. Tonight, tonight, tonight, I'm walking on air. Slowly swallowing down my fear, yeah yeah. Growing fast into a bolt of lightning. So hot and heavy, 'Til dawn. That fairy tale ending with a knight in shining armor. Heavy is the head that wears the crown.</p></div></li><li class="media my-4"><img src="../images/a1.jpg" class="mr-3" alt="..."><div class="media-body"><h5 class="mt-0 mb-1">List-based media object</h5><p>Maybe a reason why all the doors are closed. Cause once you’re mine, once you’re mine. Be your teenage dream tonight. Heavy is the head that wears the crown. It's not even a holiday, nothing to celebrate. A perfect storm, perfect storm.</p></div></li><li class="media"><img src="../images/1.jpg" class="mr-3" alt="..."><div class="media-body"><h5 class="mt-0 mb-1">List-based media object</h5><p>Are you brave enough to let me see your peacock? There’s no going back. This is the last time you say, after the last line you break. At the eh-end of it all.</p></div></li>
</ul>
