javascript代码运行维基百科API根据用户的搜索字词返回的每个返回对象。然后它将图像放在一个带有类&#34; entryImg&#34;的div中。以及名为&#34; entryTxt&#34;的div中的条目文本。然后将它们中的每一个放在一个标记为outterDiv的div中,该div被附加到我的HTML中已经使用id&#34; bodyDiv。&#34;我的问题是,在每个outterDiv中,无论我多少改变边距,为什么图片和文本的格式彼此如此接近。我把5px放在文本左边距上,5像素放在图片右边距上,可以看出并且更改没有出现在浏览器中。为什么这样,我该如何解决?
答案 0 :(得分:1)
根据您的javascript代码,生成的HTML将是
<div id="bodyDiv">
<div class="entry">
<div class="entryImg"></div>
<div class="entryTxt">
<h2>lorem ipsum</h2>
<p>lorem ipsum</p>
</div>
</div>
</div>
并且,使用您的CSS,您可以通过
增加图像和文本之间的空间在margin-right
上增加.entryImg
.entryImg {
margin-right: 10px;
}
或者在margin-left
上添加.entryTxt
之后增加overflow: hidden;
。
.entryTxt {
margin-left: 10px;
overflow: hidden;
}
