Accessibility: A feature forgotten in applications?
Accessibility is the newest concept being incorporated in an Angular certification course. Most software teams concentrate on software architecture, performance, security, testability, and maintainability of the software. However, they forget to acknowledge the importance of accessibility. According to an analysis, by WebAIM, called WebAIM Million in February 2019, 98.7% of websites didn’t meet the WCAG 2 Conformance (Web Content Accessibility Guidelines). The results made everyone realize the importance for accessibility. Therefore, this is taught to students in an Angular certification course.
Learning to design for better accessibility during an Angular certification Course
It is essential for Angular developers learn about accessibility during an Angular certification Course. For this reason that, accessibility should start from the UI design phase. Thus, Designers must create color palettes that are in line with accessibility standards. Furthermore, to make readability clear for the users, they need to choose the right typography. Most importantly, they must ensure that users with cognitive issues do not face problems in reading and understanding the content of the application. Finally, they should use Responsive Design so that the application is accessible from various devices. They learn these aspects in an Angular certification course.
Accessibility Issues solved through Semantics taught in Angular certification course
Several accessibility issues can be resolved using native components with proper semantics. As a result, the SEO in the applications would be strengthened in the process. There are some rules which are taught in an Angular certification Course:
Use semantic tags like nav, aside, main, section, fieldset, header, footer etc. instead of just using div and span’s.
Use the correct order for headings (h1-h6).
Use alt attribute on img element.
Use buttons for clickables. If a non-interactive element is used for the click event, make sure to add key events for keyboard accessibility.
Associate label with the form control.
Avoid positive tabindex .
Add captions for video and audio.
All in all, these were the rules to solve accessibility through semantics. Every aspect would be covered in an Angular certification Course.
Optimizing accessibility for interactions
There are two ways to optimize accessibility for various interactions. These are also taught in an Angular certification Course. They are
1. Keyboard Navigation: Keyboard navigation is to be taken care of when the users have motor disabilities. Developers should ensure that the tab order is in a consistent order. This will help users navigate the website using just the keyboard. However, they also should note TAB key is not the only key to be supported by them. Accounting for other keys can be learnt in an Angular certification Course.
2. Focus Management : Focus Management is also critical for accessibility field. Users who use a screen reader or keyboard must be redirected to the right place. This should take place when either when an interaction occurs or there is a change in the route.
To conclude, those who have completed an angular certification course can make the web a better place with better features.
