Must Know HTML5 Tags

You should become familiar with must know HTML5 tags that appear on almost every page.

If you want to put an image on your page then you will need to use the <img> tag with a src attribute. The source attribute contains the URL for your image.

For an example you can go to Google Images. Be sure to click on ‘Search Tools’ and ‘Labeled for Reuse’ so you do not violate any copyrights. Search for an image you like, right-click on it, and select ‘Save Image URL’.

Example of HTML5 <img> Tag

Here is an example of how to edit your HTML5 tag to display a standard Google image.

<img src=”” />


Note that the image tag is self-contained. It does not have a separate </img> closing tag.

Example of HTML5 <img> Tag with Size Percentage Attribute

Here is an image of some bananas, with the width adjusted to 50%:

<img src=”” width=”50%” />


Notice that you can use a percentage for adjusting the width. This is a nice feature to give your site a responsive quality.

Example of HTML5 <a> Tag Wrapped Over <img> Tag

You can also make the image a link itself. You can do this if you want to direct a user to another URL by clicking on the image.

The following is an example of how to edit your code so the image of bananas links to an article about bananas.

<a href=””>
++++<img src=”” width=”50%” />


As you can see, you simply put the <img> tag inside the <a> tag. Wrapping tags inside tags is a common practice with HTML5 editing, and it can go several layers deep. However, it is not permitted to overlap tags.

For example, the series of tags <p> <h2> </p> </h2> is not allowed. You can probably see by now why overlapping tags does not make sense.

Example of Using HTML5 Smaller Header Tag

You can make a smaller heading as follows:

<h3>This is a smaller heading. Use it where you want a small heading.</h3>


Example of HTML5 List Tags

You can also creat a numbered list, or as the tag suggests, an ordered list as follows:

<h4>Top Three Rock Guitar Players</h4>
++++++++<li>Jimi Hendrix</li>
++++++++<li>Jimmy Page</li>
++++++++<li>Eddie Van Halen</li>


You can also do an un-ordered list that shows bullet points.

<h4>Random Prime Numbers</h4>


Lists can add a nice dynamic to your page content. You can practice making lists at this free and interactive HTML Lists Tutorial at W3 Schools.


There are no universal rules on how to use indentations, but you should try to edit it so that it’s easy to read. Your eyes will thank you later. Writing clean code could also help you land a job.
