Here I list some: -

Blind people: - Browse the web using screen readers
People with low vision: - Use extra large monitors and also increase default font size.
Deaf people: - Use captions to understand any audio content.
People with motor skills deficiency: - Use things like head-mouse, head-pointer or mouth-stick, voice-recognition software, an eye-gaze system or other assistive technologies.

```
<img src="myPic.jpg" alt="here goes the alternative text" />
```
If you are using any image to perform an action you should provide the alternative text according to the action not the image,for example:- Say you have an image of a home which you are using to navigate to home page instead of naming alt as "home" you should name its action which will be "navigate to homepage".
Headings: - Heading provide a structure to your website's content and makes it obvious for any disabled person where something end and a new thing starts that is why we should employ using different number of heading tags for different level of heading. As we know heading tag ranges from h1 to h6.
Contrast ratio: - The color of the text and background can influence people's difficulty to comprehend the text. Some people are unable to read dark text on light background and vice versa. So to counter this most people use contrast ratio of colours so that text get's accessible for everyone. The contrast ratio used for normal-size text is 4.5:1.
