How to Change Video Thumbnails on RebelMouse

When users create an article in the Particle Assembler that includes videos, a default thumbnail image appears when the video is uploaded to the Entry Editor. However, sometimes a video does not have a placeholder image or the image is something you want to change.


If the default image is not preferable, it is easy to change with custom CSS. Here is a step-by-step of how to do it.

First, find the image you would like to use as the video thumbnail. Then, use that image URL for the next steps. First, locate the post ID in the CSS. Using the Inspect function, you should find the post ID inside the tag <article>.

You can also easily find your Post ID In the URL of any RebelMouse article.

Now, using the specific post ID, you can change the background image for the <div> that contains code video you want t update. In the example below, the name 'no-image' is used to target the <div>.

In case there are many spots with the same name, you will need to use the CSS selector "first-of-type" or "first-child" to grab the specific occurrence you want to change.

Once you have found the specific element you want to change, apply the following rules:

/*set a thumbnail for one specific post*/
.post-2604691972 .listicle-slideshow__thumbnail > div.no-image {
      background-image:  url('put the url created in the first step here');
  }

Finally, remove the icon that is hovering your picture with the following rule:

.post-2604691972 .listicle-slideshow__thumbnail > div.no-image path {
     display: none;
 }

Once the custom CSS is updated, you should see your new image as a thumbnail option in the post.

How to Add a Placeholder Image for Articles on Google AMP

The process is similar if you are publishing on Google AMP, but you need to use custom AMP CSS through our Layout & Design tool to make sure you are grabbing the target element only. Here is where to find it:

For AMP, use the same image URL as the previous example. To find the AMP-specific CSS rule that will only grab the desired post and the <div> you need, inspect the article's code to find the right place.

Then, inside your post, find the element you want to change the background image. In the example below, the CSS selector "first-of-type" is used to isolate only the first occurrence of the carousel image:

/*set a thumbnail for one specific post*/
.css-listicle-body-2604691972 button.amp-carousel-slide.amp-scrollable-carousel-slide:first-of-type {
 background-image: url(https://media.fox16.com/nxsglobal/fox16/photo/2018/09/07/Interview_with_Mother_of_Botham_Jean_0_54547264_ver1.0_640_360.jpg);
       background-size: cover;

Finally, remove the default image in order to see your new background image. In order to do that, set the <img src> of target element to "none."

.css-listicle-body-2604691972 button.amp-carousel-slide.amp-scrollable-carousel-slide:first-of-type amp-img[src]{
display:none;
}

Once completed, here is how the additional thumbnail will look on Google AMP:

The Intersection of Design and Development: Where Your Clients Thrive

We started RebelMouse seven years ago knowing that there was a fundamental design flaw in the world of traditional CMSs: Every instance, on every platform, had to be updated independently. It's similar to an era when users had to manage their own Microsoft Exchange Server for email. The costs of managing, maintaining, and iterating on a CMS to keep it awesome and world class is typically a $10 million-a-year endeavor. But even then, these cost-prohibitive CMSs are still behind the times.

Native Multivariate Testing at Scale With RebelMouse

What Differentiates Our Approach

There are many popular tools that allow you to perform experiments and A/B tests on your users — primarily Google Chrome Experiments and Optimizely. But all of these solutions are JavaScript additions to your web page that sidestep the problem of old, outdated, and clumsy CMSs. These solutions work by calling on a third-party JavaScript library that rewrites a page after it's rendered. This approach adds extra page weight and creates strange user experiences due to having to wait for everything to load and be rewritten on the fly.

At RebelMouse, we've solved this in a very elegant way. At the core level of our platform, we can natively render different layouts and track the exact differences in performance when comparing a test to your other layouts.

How to Monetize Your Website in Today’s Publishing Environment

In order to define distributive publishing, we have to ask the following question: If you have quality content, but nobody sees it, does it even exist? The answer is no, because your content needs to be supported in a way that lets it move seamlessly across all channels, especially site, search, and social. But let's take this question a step further: If you can't monetize your content to generate the support it needs, how do you create quality content in the first place?

A Modern Story of Web Performance From RebelMouse Founder + CEO Andrea Breanna

If I had more time, this website would have loaded faster

In the first months of 2020, we've focused at RebelMouse on page speed and performance. We worked very hard and found ways to take 90% of the sites we power to 90+ performance scores via Google's PageSpeed Insights tool — even with sites that are loaded with ads, embeds, third-party analytics, and other typical slow-loading elements. You can read more about our victories here.

A few months after we started this process, COVID-19 hit the world very hard. Suddenly, every media company was faced with a huge problem: Advertising fell off a cliff in what seemed like seconds. The only way to survive this unprecedented downturn is to grow traffic and control costs at the same time. So we started to shave our code and made our websites faster. We dropped costs just as dramatically as we were increasing scores.

Here are some surprises we found when doing this: If you want truly exceptional performance, none of the JavaScript and CSS frameworks that developers love so much make the cut. We thought the React version of RebelMouse was going to be the huge page speed breakthrough, until we realized the only way to achieve this goal was to write the code carefully and refactor it endlessly until it was as short as possible. As any author will tell you, like editing a book or a blog post, the revision process is never really done. By stepping away from frameworks, and methodically shaving vanilla code, our customers continue to see major improvements in performance.

As we announced this to our site network and rolled it out publicly, many of our clients asked me personally, "How did you do it?" The answer is easy to understand regardless of how technical you may be. It's perfectly summarized in this wonderful quote attributed to Mark Twain:

"If I had more time, I would have written a shorter letter."
—Blaise Pascal, 1657 (and later, more famously Mark Twain)

The universe is sometimes very beautiful, and especially when you keep it simple. If you would like to start publishing on a site optimized for both speed and sustainability, request a proposal and let's start working together.
