HTML: Video
As with audio, until recently it was impossible to "comfortably" insert a video file into HTML markup. Since HTML5 there is a <video> element that, like <audio>, allows you to quickly add videos to a page.
The <video> tag is paired, which, in the absence of nested <source> tags, specifies the path to the video file in the src attribute. You can use the controls attribute to display controls for the video player. The visual appearance of the controls depends on the specific browser.
<video src="https://example.com/our-video.mp4" controls></video>
By using special <source> tags, you can add multiple video formats. This is necessary because each browser can only play certain video formats. The only format that all browsers handle correctly is mp4.
<video controls>
<source src="https://example.com/our-video.mp4" type="video/mp4">
<source src="https://example.com/our-video.webm" type="video/webm">
<source src="https://example.com/our-video.ogg" type="video/ogg">
</video>
Three file formats ensure that videos work on all devices. You also need type attribute, which will tell the browser the format of the video. It's this attribute that the browser uses to decide which file to download.
The <video> tag has several important attributes:
controls— Adds controls for the video playerautoplay— Automatic playback after loading the videowidth— Width of the video playeheight— Height of the video player
The width and height attributes are pixel values, and you don't need to specify the unit of measure.
<video width="500" height="500" controls>
<source src="https://example.com/our-video.mp4" type="video/mp4">
<source src="https://example.com/our-video.webm" type="video/webm">
<source src="https://example.com/our-video.ogg" type="video/ogg">
</video>
Instructions
Add an mp4 video to the page:
- Video link: https://www.w3schools.com/html/movie.mp4
- The video player should have controls
- Player height: 240
- Player width: 320
- Enter the path to the file in the
<video>tag
Turn your volume down just in case ;)
The exercise doesn't pass checking. What to do? 😶
If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:
- Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.
In my environment the code works, but not here 🤨
Tests are designed so that they test the solution in different ways and against different data. Often the solution works with one kind of input data but doesn't work with others. Check the «Tests» tab to figure this out, you can find hints at the error output.
My code is different from the teacher's one 🤔
It's fine. 🙆 One task in programming can be solved in many different ways. If your code passed all tests, it complies with the task conditions.
In some rare cases, the solution may be adjusted to the tests, but this can be seen immediately.
I've read the lessons but nothing is clear 🙄
It's hard to make educational materials that will suit everyone. We do our best but there is always something to improve. If you see a material that is not clear to you, describe the problem in “Discussions”. It will be great if you'll write unclear points in the question form. Usually, we need a few days for corrections.
By the way, you can participate in courses improvement. There is a link below to the lessons course code which you can edit right in your browser.
Tips
If only one file is used, it's enough to add the
srcattribute for the<video>tag. Otherwise use<source>tagsThe
mp4format is correctly handled by most browsers. If possible, it's best to use it.
