Gif 打破了 Gatsby 网站的响应能力

Question

• Problem Summary

There are two.gif images in my blog post, which are breaking the responsiveness of my site, they don't seem to get resized when opened on a mobile device. Although they seem to be fine when opened from pc.

PC view:

Mobile view:

As you can see, in mobile view the two.gif images are still the same size, which breaks the responsiveness of the page. Is there a way I could solve this issue?

• The syntax I've used to include the.gif in my.mdx file is-

  .[otter dancing with a fish](./neural_net_data_manupulation_2.gif)

• Config.js file of my site:

require(`dotenv`).config({
  path: `.env`,
})


const shouldAnalyseBundle = process.env.ANALYSE_BUNDLE

Answer 1

The HTML on the question's page shows that the GIF images for figure 6(a) and 6(b) are not responsive.

Here is the HTML for figure 6(a):

<th class="css-hep4zx"><img  src="...gif" class="css-0"></th>

Note that no responsive classes are present.

And here is a responsive PNG figure 3(a), with very different markup:

<th class="css-hep4zx"><span
    class="gatsby-resp-image-wrapper"
    style="position: relative; display: block; margin-left: auto;
      margin-right: auto; max-width: 650px;">
    <span
      class="gatsby-resp-image-background-image"
      style="padding-bottom: 100%; position: relative; bottom: 0px;
      left: 0px; background-image: url(...); background-size: cover;
      display: block;"
    ></span>
    <img
      class="gatsby-resp-image-image css-0"
      src="(...).png"
      style="width: 100%; height: 100%; margin: 0px; vertical-align: middle;
      position: absolute; top: 0px; left: 0px;"
    >
  </span>
</th>

Why the PNG vs GIF Difference?

The very different HTML markup generated for .png and .gif images appears to be a limitation of the gatsby-remark-images plugin. From the documentation:

Supported Formats

This plugin will support the following formats:

• JPEG
• PNG

Conclusion: The gatsby-remark-images plugin does not generate responsive HTML for gifs.

So what now?

So if the gatsby-remark-images plugin won't make responsive GIFs, is there a plugin that will?

Let's experiment with a different plugin, here's a sample gif to try:

Using the gatsby-remark-interactive-gifs , with the recommended CSS styling, produces HTML like this:

 /* CSS copied from `gatsby-remark-interactive-gifs` page */.interactive-gif {}.interactive-gif.embedded { position: relative; width: 100%; height: auto; }.interactive-gif.gif-container { position: absolute; top: 0; width: 100%; height: 100%; }.interactive-gif.gif { width: 100%; height: 100%; cursor: pointer; }

 <div class="interactive-gif"> <div class="embedded" style="padding-top: 56.28517823639775%"> <div id="nyancat.gif" class="gif-container" style="display: block;"> <img id="image-nyancat.gif" class="gif" data-original="https://i.stack.imgur.com/f7DcY.gif" src="https://i.stack.imgur.com/f7DcY.gif"> </div> </div> </div>

The resulting GIF image is indeed responsive, so it seems that using gatsby-remark-interactive-gifs does produce responsive GIFs.

Answer 2

The issues come because your layout is wrapped in a <table> tag, with an inherit display: table . It's a CSS issue so you will need to change the rules for that table, forcing the wrap of those gifs.

If you are able to change your HTML structure, I would suggest a more flexible and simple structure, such as:

<div className="your-flex-wrapper">
  <img src="gif1"/>
  <img src="gif2"/>
</div>

The wrapper should have a:

.your-flex-wrapper{
   display: flex;
   flex-flow: row wrap;
}

I've applied these changes live to your site (in the th and tr tags) and:

However, it's not semantic to add a display: flex to a table layout so, it will be better to change the structure accordingly.

If you force the width of the .gif to a 100% of the viewport on small screens, they will always be responsive.

Answer 3

I was able to solve my problem with a pretty easy solution. I've just integrated Bootstrap into my Gatsby system and then used some basic bootstrap grid classes to make the.gifs responsive.

The way I solved it:

1. Firstly , install the bootstrap plugin-

   npm install react-bootstrap bootstrap

2. Then , import the plugin where necessary (I've imported it in my post's.mdx file where I've defined those.gifs)-

   import 'bootstrap/dist/css/bootstrap.min.css'

3. Lastly , I've just used the bootstrap way of doing things to make those.gifs responsive (that's how I defined those.gifs in my.mdx file)-

<div class="container">
  <div class="row">
    <div class="col-sm-12 col-md-6 col-lg-6">
      <img src="./neural_net_data_manupulation_2.gif" style="width: 100%;"/>
      </div>
    <div class="col-sm-12 col-md-6 col-lg-6">
      <img src="./neural_net_decision_boundary.gif" style="width: 100%;"/>
      </div>
  </div>
</div>

That's how they look now:

• Big display (PC)-

• Small screen (mobile)-
