问题
I am basically styling a long essay with various images scattered throughout. I would like the first image to "float: left" and the second one to "float: right". I know that I can style the images like this:
img {
float: left;
}
This makes each image have the same style. How do I style each image differently? I tried to put each image in a different div class, so that I could style them differently, but it didn't work.
I also understand, that I could style each image in the html tag, like this:
<img src="ABCD.png" alt="Raoul Hausmann's ABCD" align="left" height="300px">
I keep hearing that it is best to keep style in the external style sheet (CSS), separate from the html. Is this a case where inline styling is necessary?
回答1:
You can give each image a class or id that will help you to define different css for each image like
<img src="" class="image1">
<img src="" class="image2">
in css file you can define
.image1
{
width:200px;
height:200px;
}
.image2
{
width:300px;
height:300px;
}
回答2:
Give your image a class and then you can style all images with that class like this:
.left {
border: solid 5px red;
float: left;
}
.right {
border: solid 5px blue;
float: right;
}
<img src="ABCD.png" class="left">
<img src="ABCD.png" class="right">

Try this
img{width: 200px;height:200px;background-color: antiquewhite}
.left{float:left}
.right{float:right}
<img src="ABCD.png" alt="Raoul Hausmann's ABCD" class="left">
<img src="ABCD.png" alt="Raoul Hausmann's ABCD" class="right">
this will float two images one in left and another in right

All the above are fine, I would only suggest grouping the common settings of picture in this case so that the left/right classes only contains that what is different.
/* Group the common attributesso that you only need to set it once */
.picture, .leftPicture, .rightPicture {
border: 2px dotted gray;
width: 200px;
}
.leftPicture {
float:left;
}
.rightPicture {
float:right;
}
