私は次のようなHTMLを持っています:
<div id='container'>
<div class='left mr1'>
<img src='https://placehold.it/100x50' srcset='https://placehold.it/200x100 2x'>
</div>
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
</div>
CSS は次のようになります。
#container {
width: 400px;
background: #eee;
padding: 10px;
}
.mr1 {
margin-right: 10px;
}
.left {
float: left;
}
Firefox でのみ、"retina" ディスプレイで表示すると、.left
div
(指定されていないwidth
) の幅が 2 倍になります。これを他のブラウザで複製することはできません。
