HTML has plenty of practical secrets that might come in handy.
But I do want to make sure that the site is working on Internet Explorer and other browsers.
I use Endtest to create automated tests and execute them on the cross-browser cloud.
Netflix uses the same platform to test their web apps.
It's even listed as a Required Skill for some of their jobs.
Endtest does have some really nice features, such as:
• Cross-browser grid, running on Windows and macOS machines
• Codeless Editor for Automated Tests
• Support for Web Applications
• Support for both native and hybrid Android and iOS apps
• Unlimited Video Recordings for your test runs
• Screenshot Comparison
• If Statements
• Upload files in your tests
• An Endtest API, for easy integration with your CI/CD system
• Advanced Assertions
• Mobile Tests on real mobile devices
• Email testing with Endtest Mailbox
You should check out the docs.
Below are 9 extremely useful HTML tricks.
This can be used to mark up a photo.
<figure> element can also contain a
<figure> <img src="https://thepracticaldev.s3.amazonaws.com/i/g84et7kjgp2phal89140.jpg" alt="Swat Kats" style="width:100%"> <figcaption>Fig.1 - SWAT Kats</figcaption> </figure>
And this is what it would look like:
This allows you to embed a media player for video playback.
For example, you can upload your video on AWS S3 and use the
<video> tag to embed it on your website.
Using YouTube for that might come off as unprofessional.
And Vimeo doesn't allow you to embed your videos without paying. ☹️
You can specify certain attributes, such as width, height, autoplay, loop, controls, etc.
<video autoplay="" loop="" controls="" width="640" height="480"> <source type="video/mp4" src="https://endtest-videos.s3-us-west-2.amazonaws.com/documentation/endtest_data_driven_testing_csv.mp4"> </video>
And this is what it would look like:
You can also embed a live stream using getUserMedia() or WebRTC
This tag helps you display images in a responsive manner, by showing an alternative image version for smaller viewports.
It needs to contain one or more
<source> tags and one
<img> tag will be used only if the viewport doesn't match any of the
<source> tags or if the browser does not support it.
<picture> <source media="(min-width: 968px)" srcset="large_img.jpg"> <source media="(min-width: 360px)" srcset="small_img.jpg"> <img src="default_img.jpg" alt="avatar"> </picture>
<progress> tag represents the progress of a task.
<progress> tag should not be confused with the
<meter> tag (which represents a gauge).
<progress value="63" max="100"> </progress>
This is what it looks like:
You can use the
meter element to measure data within a given range (a gauge).
This can be achieved with min and max values or with a percentage.
<meter value="2" min="0" max="10">2 out of 10</meter>
And here they are:
<map> tag is used to define a client-side image-map.
An image-map is an image with clickable areas.
All you have to do is mention the X and Y coordinates in the elements from the
This means that you create a map of our Solar System and define areas for each planet and take the visitors to a separate page for each planet they click on.
<img src="solar_system.png" width="500" height="300" alt="Planets" usemap="#planetmap"> <map name="planetmap"> <area shape="rect" coords="0,0,52,92" href="earth.htm" alt="Earth"> <area shape="circle" coords="60,48,5" href="mars.htm" alt="Mars"> <area shape="circle" coords="135,48,12" href="saturn.htm" alt="Saturn"> </map>
7. The contenteditable attribute
This attribute specifies whether the content of an element is editable or not.
<p contenteditable="true">This is an editable paragraph.</p>
8. Input suggestions
<input type="text" list="planets"> <datalist id="planets"> <option value="Mercury"></option> <option value="Venus"></option> <option value="Earth"></option> <option value="Mars"></option> <option value="Jupiter"></option> <option value="Saturn"></option> <option value="Uranus"></option> <option value="Neptune"></option> </datalist>
I hope you don't mind that I didn't add any styling.
I prefer to keep things as vanilla as possible in my examples.
The content inside the
I think it's really cool that you're looking for HTML tricks, but are you sure your Web Application is working correctly on all browsers and devices?
You can use Endtest to quickly create Automated Tests and execute them on the cross-browser cloud.
You don't even have to code in order to use it.
Seriously, just read the docs.

I LOVE the datalist tag and appreciate anyone who helps evangelize it! It can also be combined with
autocomplete='off'on the element that its used with so that you don't get annoying values in there. For instance if you have a list of employees and the type of the input is set to email, you wouldn't want all of your emails that you use to be autocompleted.
Also you can add stuff into option for better autocomplete.
with this searching names, or email will work. Even partials like 'ty@examp' will work and only bring up Arty.
The above example can be seen in this fiddle: jsfiddle.net/t2qb90vu/
Thanks! I was just in a desperate need for this kind of searchable list! :)
Glad to help! :D
Thank you for sharing this with us.
No problem! I'm a real big fan of not using JS or adding custom logic where you can get away with it. As a result I'm a HUGE fan of the datalist tag for autocomplete and also the
detailstag for most accordions. Especially on smaller sites.
Glad I that you and others find this useful. :)
dev.to actually uses the details tag for its accordion to close comment threads! The little arrow on the left of comments is via the details tag. You can see it via inspect element! :D
The map tag I have seen before in legacy websites. Where the Devs where lazy and put an image of an menu in the headers. And made it clickable using a map. And people needed to shuffle some items around... In the image...
Such a classic example of a good concept used in wrong way.
Thank you for sharing that.
Man, last time I've used
<map>was, like, last century... 😂
Pretty much abandoned and with a weird interface, it's still completely supported. It was actually pretty advanced at that time.
Wow, I had no idea that there was a native HTML typeahead-like control. Thanks!
Glad you liked it.
I never knew there was a progress tag. TIL.
No.7 was awesome :D, thanks bro
Wow, there is some great stuff in this, thanks for sharing!
Figure with img could use some srcsets.
Love the datalist tag.
Love the idea of Input Suggestions — I didn't know about that one!
How's accessibility with the image map? Hopefully with the outline, alts and link titles it is fine.
thank you for sharing tricks :)
Image maps? Like in 1998? Next we'll slice them up in tables ;)
Otherwise there is some good stuff here
contenteditable... had no idea!! Thanks for this Klaus, great read 🤜👍
