p 标签内可调整大小的 img，其宽度大于容器

Question

我正在使用 Ghost 博客平台，当我插入图像时，它会自动将图像包装在 p 标签中。我为包装 p 标签和 img 的容器设置了最大宽度。我希望 img 比容器大。我可以为 img 设置一个更大的宽度 width: 62rem; 但是它不再响应 width: 100%;

我希望在调整浏览器大小时调整 img 的大小，我希望在没有媒体查询的情况下这样做，但如有必要我会这样做。

我已经更改了所有 p 标签的大小，以便我的块引用是容器部分的大小，我希望我的图像也这样做，但它只是 p 标签的大小。我主要关心的是使 img 响应式和更大，我已经可以以指定的宽度自行使其更大，但它不再保持响应式。

提前致谢。

<p>After debating for a while of whether to use a Zurbs Foundation, I have decided to go with html5 boiler plate custom, I want the site to be as minimal as possible and it is simple enough I dont need a massive template to still to rapid development, however it is nice to have the goodies bundled with html5 boiler plate have the option to remove the stuff that I dont need. Below is a list of what I used and why.</p>


<p>I am using docpad for this project, docpad is like static pages on steroids. So far I am loving it for fast development. I am using the no template and building from scratch, plopping in my custom html5 boiler plater contents.</p>

<p>I read this article <a href="http://alistapart.com/article/the-infinite-grid">http://alistapart.com/article/the-infinite-grid</a> and it is a great starting point for creating a responive site. It really hits home the theory, and not so much specifics about a one fit solution for a website.</p>

Answer 1

我认为您不应该有一个特定大小的 div，然后在其中的一个元素 打破 div，因为您已将其设置为大于 @ 987654322@

第一件事我要做的是重新组织容器的工作方式。这里是a FIDDLE 的一些基本 html 供参考。

第二件事我会做的 - 是问一个更有针对性的问题，关于从幽灵论坛中的图像中删除自动 p 标签（假设它们现在存在）。

在 WordPress 中，默认情况下也会发生这种情况。它看起来像这样，带有一个运行正则表达式搜索和替换的函数。我敢打赌，ghost 会有这样的东西，或者真的很快就会有——因为这是一个巨大的痛苦——几乎没有人真的把图像内联了。如果他们这样做了，他们会想要控制这种情况何时发生。

function filter_ptags_on_images($content) {
  // do a regular expression replace...
  // find all p tags that have just
  // <p>maybe some white space<img all stuff up to /> then maybe whitespace </p>
  // replace it with just the image tag...
  return preg_replace('/<p>(\s*)(<img .* \/>)(\s*)<\/p>/iU', '\2', $content);
}

// we want it to be run after the autop stuff... 10 is default. ? ? ?
add_filter('the_content', 'filter_ptags_on_images');

祝你好运！我希望很快能和 Ghost 一起玩，我敢打赌这也是我遇到的第一个问题。

Answer 2

您也设置了 100% 的宽度图像，但也给它边框。这会导致问题。

您需要从图像中减去边框数量。

试试：

#postSelect p img {
    width: calc(100% - 2rem);
    border: 1rem solid #fff;
}
