在图片前的内容上应用CSS边距

Question

I have text content and images mixed and want to apply css margin to elements directly before and after images (

, , can come before or after the image, but I have no control on which one and where)

I am using the following code to apply margin to the elements before the image

#single-pg * + img { margin-top: 75px; }

Problem is that it adds the margin-top to other images aswell (I want it to apply to all elements EXCEPT images) and I want to add similar to affect content elements after the image

#single-pg img + * { margin-bottom: 75px; }

html (Wordpress)

<div id="single-pg" >
    <?php the_content(); ?>
</div>

so the outcome could be (but could also be in any other order based on the author)

<h2>Title</h2>
<image></image>
<image<</image>
<p>text</p>
<p>text</p>
<p>text</p>
<image<</image>

Answer 1

Not entirely clear from your description of the issue (and it's hard without seeing your markup); however, if you want margin-top and margin-bottom to apply to every element except for images, I'd make use of the :not selector.

:not(img) {
    margin-top: 75px;
    margin-bottom: 75px;
}

EDIT

To target the paragraphs in a more nuanced way, we'll have to use some scripting. We can use the adjacent sibling selector to add our margin-top value:

img + p {
  margin-top:75px;
}

and then we can use the jQuery .prev() method to target the paragraph immediately preceding each image:

$("img").prev().css("margin-bottom", "75px"); 

Here is an updated fiddle of an example in action. Let me know if that helps.

将图像和文本放入包装器中，将每个图像和文本放入另一个包装器中，就可以管理每个图像的边距。
