 The truth is, you're right to a certain degree. If you have done meticulous user research and have excluded any chance of a certain group of people visiting your website, the priority for catering to that group diminishes.

 Visually, the second element looks like a heading after styling it with CSS, but semantically it is a `span`. Thus, assistive technologies won’t know it's a heading. A screen-reader will read this element as regular text instead of a heading. Screen-readers that use a hotkey to jump between headings would skip this element.

 Spans and divs are not semantic elements; they do not provide the contextual meaning of a particular element to web browsers, search engines, or assistive technology.  You can fix these in two ways:

There are also hotkeys to jump to the next table, form field, link, etc. Thus, it is good practice to make sure these headings are actually in logical places.

-Also remember that headings are hierarchical. If you use an `h2`, make sure the `h3`s that follow it actually have something to do with that `h2`. Don't put an `h3` for contact details under your `h2` for recent blog posts. A good analogy here is a book with chapters, that have subsections. You wouldn't put a section on baking cookies in the middle of a chapter on preparing vegetables, right?

 ### What's the alternative?
 Images on a website are great. They add a new layer to your content, make experiences more immersive, and generally look good among all the text. A picture can say more than a thousand words, right?
 
-Certainly. That is, if you can see them. In the HTML5-specification,  an img-attribute must always have an alt-attribute. This attribute is  meant as an alternative to the image in case it is not visible. This  would be true for blind visitors to your website, but also when your  image doesn't load for some reason. Not adding an alt-tag to an  img-attribute not only breaks accessibility, it goes against the HTML5-spec.

 Now, there is one caveat here. Alt-attributes are mandatory according to the HTML5-spec, but it is not mandatory to fill them in. `<img src="awesome-image.jpg", alt="">` is therefore legal HTML5 code.

 For images that contain information, like a map or chart, not adding alt text breaks WCAG unless you provide a textual alternative. This is usually an alt-attribute, but can also be a block of text right below or next to the image.
 
-For images of text, the text can either be included in the  alt-attribute or offered in some alternative manner. The problem with adding the textual alternative on the same page is that the same content would show twice for people who can see the image, making the alt-attribute a better option.

 The text should provide the context and information that is an alternative to seeing the image. It is simply not enough to write "image of hot air balloons" – why are the balloon pictures there? If the image is stylized or conveys an emotional meaning, this can be included.
