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.

You can use use Endtest to create automated tests and execute them on the cross-browser cloud.

Below are 8 extremely useful HTML tricks.

1. The <figure> tag

This can be used to mark up a photo.

The <figure> element can also contain a <figcaption>:

 <img src="" alt="Swat Kats" style="width:100%">
 <figcaption>Fig.1 - SWAT Kats</figcaption>

And this is what it would look like.

2. The <video> tag

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.

And this is what it would look like.

You can also embed a live stream using getUserMedia() or WebRTC

3. The <picture> tag

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.

The <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.

  <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">

4. The <progress> tag

The <progress> tag represents the progress of a task.

The <progress> tag should not be confused with the <meter> tag (which represents a gauge).

<progress value="63" max="100">

And this is what it would look like.

5. The <meter> tag

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>
<meter value="0.6">60%</meter>

And this is what they would look like.

6. The <map> tag

The <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 <map>.

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">

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>

And this is what it would look like.

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>

Here it is.

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.
