How to expand embedded video player html css

Written by Jamie Juviler. If you want to engage first-time visitors on your website, you have about 10 to 20 seconds. To inject some life into your page content, you might want to try adding a background video with CSS. Video backgrounds take up the entire width and height of the viewport in other words, the visible page area and add some visual flair to boost engagement. Over this video, you can place your featured page content — after all, it is just a background, and your content is most important.

Adding Media

Many sites use third-party embeds to create an engaging user experience by delegating some sections of a web page to another content provider. The most common examples of third-party content embeds are video players, social-media feeds, maps, and advertisements. Third-party content can impact the performance of a page in many ways. It can be render-blocking, contend with other critical resources for network and bandwidth, or affect the Core Web Vitals metrics. Third-party embeds may also cause layout shifts as they load.

This article discusses performance best practices that you can use when loading third-party embeds, efficient loading techniques, and the Layout Shift Terminator tool that helps reduce layout shifts for popular embeds.

What is an embed A third-party embed is any content displayed on your site that is: Not authored by you Served from third-party servers Embeds are frequently used in the following: Websites related to sports, news, entertainment, and fashion use videos to augment textual content.

Organizations with active Twitter or social media accounts embed feeds from these accounts to their web pages to engage and reach out to more people. Restaurant, park, and event venue pages often embed maps. This can make the third-party embeds heavy and affect the performance of the page by delaying its first-party content. They take more time to load and keep the main thread busy when executing.

Performance monitoring tools such as Lighthouse and Chrome DevTools help to measure the impact of third-party embeds on performance. Reduce the impact of third-party code Lighthouse audit shows the list of third-party providers a page uses, with size and main-thread blocking time. The audit is available through Chrome DevTools under the Lighthouse tab.

It is a good practice to periodically audit the performance impact of your embeds and third-party code because embed source code may change. You can use this opportunity to remove any redundant code. Third-party embeds can negatively impact performance, but they also offer important functionalities. To efficiently use third-party embeds and reduce their performance impact, follow the guidelines below.

Script ordering In a well-designed page, the key first-party content will be the focus of the page, while the third-party embeds will occupy side-bars or appear after the first-party content. For the best user experience, the main content should load quickly and before any other supporting content. For example, the news text on a news page should load before embeds for a Twitter feed or advertisements. Requests for third-party embeds can get in the way of loading first-party content, so the position of a third-party script tag is important.

Scripts can affect the loading sequence because the DOM construction pauses while scripts are executed. Place third-party script tags after the key first-party tags and use async or defer attributes to load them asynchronously. Since third-party content usually comes after the primary content, it may not be visible in the viewport when the page loads. In that case, downloading third-party resources may be deferred until the user scrolls down to that part of the page.

This not only helps optimize the initial page load but also reduces the download costs for users on fixed data plans and slow network connections. Delaying the download of content until it is actually needed is called lazy-loading. Depending on the requirements and the type of embed, you can use different lazy-loading techniques explained below. The loading attribute supports the following values: lazy : Indicates that the browser should defer loading the iframe.

The browser will load the iframe when it is nearing the viewport. Use if the iframe is a good candidate for lazy-loading. Use if the iframe is not a good candidate for lazy-loading. If the loading attribute has not been specified, this is the default behavior—except in Lite mode. Browsers that support the attribute may have different implementations for the distance-from-viewport threshold the distance at which the iframe starts loading.

Following are some ways in which you can lazy load iframes for different types of embeds. YouTube videos: To lazy-load a YouTube video player iframe, include the loading attribute to the embed code provided by YouTube. Lazy loading the YouTube embed can save approximately KB on the initial page load.

If you need better control on the distance thresholds or you want to provide a consistent lazy-loading experience across browsers, you can use the lazysizes library. Once you have downloaded the component, it can be used with an iframe for a YouTube embed as follows. Similarly, lazysizes may be used with iframes for other third-party embeds.

Using data-lazy in Facebook Facebook provides different types of social plugins that can be embedded. This includes posts, comments, videos, and the most popular Like button.

All plugins include a setting for data-lazy. Lazy-loading Instagram feeds Instagram provides a block of markup and a script as part of the embed. Replace embeds with facades While interactive embeds add value to the page, many users may not interact with them. For example, not every user browsing a restaurant page will click, expand, scroll, and navigate the map embed.

Similarly, not every user to a telecom service providers page will interact with the chatbot. In these cases, you can avoid loading or lazy-loading the embed altogether by displaying a facade in its place. A map embed with a zoom in and out feature.

A map facade that is an image. A facade is a static element that looks similar to the actual embedded third-party but is not functional and, therefore, much less taxing on the page load. Following are a few strategies to load such embeds optimally while still providing some value to the user. Use static images as facades Static images can be used instead of map embeds where you might not need to make the map interactive. You can zoom in on the area of interest on the map, capture an image, and use this instead of the interactive map embed.

You can also use DevTools Capture node screenshot functionality to capture a screenshot of the embedded iframe element, as shown below.

DevTools captures the image as a png , but you can also consider converting it to WebP format for better performance. Use dynamic images as facades This technique allows you to generate images corresponding to an interactive embed at run time.

Following are some of the tools that allow you to generate static versions of embeds on your pages. The Static map maker tool helps to configure the parameters required for the URL and gives you the code for the image element in real-time.

It has been included in a link tag that ensures that the actual map can be accessed by clicking on the image. Note: API key attribute is not included in the url. Twitter screenshots : Similar to map screenshots, this concept allows you to dynamically embed a Twitter screenshot instead of the live feed.

Tweetpik is one of the tools that can be used to take screenshots of tweets. The API also accepts parameters to customize the background, colors, borders, and dimensions of the image.

The click-to-load concept combines lazy-loading and facades. The page initially loads with the facade. When the user interacts with the static placeholder by clicking on it, the third-party embed is loaded. This is also known as the import on interaction pattern and can be implemented using the following steps. On page load: Facade or static element is included on the page. On mouseover: Facade preconnects to the third-party embed provider.

On click: The facade is replaced by the third-party product. Facades may be used with third-party embeds for video players, chat widgets, authentication services, and social media widgets. YouTube video embeds that are just images with a play button are facades that we come across frequently.

The actual video loads only when you click on the image. You can build a custom click-to-load facade using the import on interaction pattern or use one of the following open source facades available for different types of embeds. YouTube facade. Lite-youtube-embed is a recommended facade for the YouTube player, which looks like the real player but is times faster. Custom player parameters supported by YouTube may be included through the params attribute.

Other similar facades available for YouTube and Vimeo players are lite-youtube , lite-vimeo-embed , and lite-vimeo. React-live-chat-loader loads a button that looks like a chat embed instead of the embed itself. It can be used with various chat provider platforms such as Intercom, Help Scout, Messenger, and so on. The look-alike widget is much lighter than the chat-widget and loads faster. It can be replaced by the actual chat widget when the user hovers or clicks on the button or if the page has been idle for a long time.

The Postmark case study explains how they implemented react-live-chat-loader and performance improvements they achieved. If you find that some third-party embeds result in poor loading performance and using any of the techniques above is not an option, the simplest thing that you can do is remove the embed entirely. Layout stability While dynamically loading embedded content can improve the loading performance of a page, it can sometimes cause unexpected movement of page content.

This is known as layout shift. Since visual stability is important to guarantee a smooth user experience, Cumulative Layout Shift CLS measures how often those shifts happen and how disruptive they are. Layout shifts can be avoided by reserving space during page load for elements that are going to be dynamically loaded later. The browser can determine the space to be reserved if it knows the width and height of the elements.

You can ensure this by specifying the width and height attributes of iframes or by setting a fixed size for static elements where the third-party embed will be loaded. For example, an iframe for a YouTube embed should have width and height specified as follows. Popular embeds like YouTube, Google Maps, and Facebook provide the embed code with size attributes specified. However, there may be providers who do not include this. For example, this code snippet does not indicate the dimensions of the resulting embed.

You can use DevTools to inspect the injected iframe after this page is rendered. As seen in the following snippet, the height of the injected iframe is fixed while the width is specified in percentage. This information can be used to set the size of the containing element to ensure that the container does not expand on loading the feed and there is no layout shift.

How to Customize an Embedded YouTube Video

The first thing that you need is the YouTube iframe embed code, grab that in your video share options from the YouTube site. Place the iframe code on your page, in this example above the iframe's container div div. This makes the content fluid as a percentage unit is used, it also has a max-width set as I don't want the video displaying wider than px. The first CSS declarations target the video container and the second target what is in the container, in this case it's the iframe , you can also apply this to objects and embed elements. That's it the video will now scale as the viewport is resized, the magic element is the padding-bottom rule of This same process can also be achieved using a javascript technique explained in the Vimeo video guide , which plays just as friendly with YouTube videos. YouTube Making YouTube videos scale in all browsers, tablets and phones for responsive design.

HTML5 Canvas by Steve Fulton, Jeff Fulton

Responsive designs are all the hype in Web development communities nowadays. With videos becoming an important marketing tool on many websites, there is a growing need to incorporate responsive videos into these designs. Responsive videos are elastic and are especially favored where web pages will be viewed on different screen sizes using a variety of browsers. Using the HTML5 video element however is not enough when handling video embed code that uses iframes and objects tags. This forces the embed elements to automatically expand full width. Check out how this has been done in the markup below:. Likewise, minimum width of the video element can be set using the min-width tag. A working demo of the above code snippet can be seen here.

Bootstrap's video gallery is a component that compiles a number of media into one interactive collection presented in a basic or a more advanced lightbox. It can be resized as desired, and thanks to Bootstrap's responsiveness, it will adjust to the screen size. Note: This documentation is for an older version of Bootstrap v. A newer version is available for Bootstrap 5. We recommend migrating to the latest version of our product - Material Design for Bootstrap 5.

Embed a YouTube video with 16:9 aspect ratio and full-width

In previous years all the video you have ever watched online has been channeled through a third party plugin such as QuickTime, Flash, or RealPlayer. Problems arise however when the user suddenly tries to view a video on a platform that is not supported. With an ever growing audience viewing video content on portable devices the problem of ensuring video can be seen on any device with any browser is of growing concern to web developers. Compounding the problem is a lack of support for many of the plugins on many of the portable browser versions such as iOS, Android, and Windows Phones — with a lack of support for Flash on all the major platforms being a major issue for many users and developers especially. The HTML5 video specification has been trying to change all that but it is still an uphill battle. Modern browsers in conjunction with new specifications in HTML5 have made adding video to a web page a much simpler affair than it used to be.

Fluid Width Video

There are lots of ways in which video can be displayed on your site. In each of these video-embedding scenarios, it is very common for a static width and height to be declared. Guess what? What if the parent container for that video shrinks narrower than the declared px? It will bust out and probably look ridiculous and embarrassing. Well, yep, you can! If you are using standard HTML5 video, that will make the video fit the width of the container. Fortunately, there are a couple of possible solutions here.

Aspect ratio — The media width and height properties, set in your curl statement when creating a player, define the intrinsic video dimensions, also known as the aspect ratio. The video aspect ratio is the relation between width and height. Classic TVs use a aspect ratio, while widescreen uses a aspect ratio.

Video embedding has become a popular aspect of web development. With recent advancements in the tech industry, developers can embed videos into various web pages.

Video is more prevalent on the web than ever before. Yet, people rarely mention video when they talk about responsive design. In order for a video to be responsive, the video should always expand to fill the width of its container while maintaining its original aspect ratio. We want to avoid static sizing that can break page layouts, distort the image, or display black bars around the video. However, we can simplify things by ignoring file types, video and audio codecs, the video player, and the video source for this discussion. What we are left with are the same concerns for responsive images: aspect ratio, quality, and file size. Specifying a fixed width and height for a video can cause layout issues.
