Do CSS Frameworks Offer Greater Accessibility?
The CSS framework or the front-end framework basically comes in a package that consists of a set of files and folders of a universal standardized code. CSS – Code Styling Sheet – plays an important role in deciding the front-end of the web app. This is what is facilitated wonderfully by CSS frameworks.
CSS frameworks allow a more flexible web page designing. Most of these frameworks make use of at least one grid. Some of the main components of CSS frameworks include the CSS source code, typography, browser compatibility, and standard CSS classes. Let us take a brief look at each below:
CSS source code: the design of the site requires a number of elements that the developer will make use of. The CSS source code allows the developer to work around these components and assemble them in order to come up with a simple yet versatile design for the site.
Typography style definitions for the different elements involved.
Browser compatibility: The developer has to ensure that all the components are in place such that the site works well on all platforms. This will make sure that the site is displayed properly on all browsers.
Standard CSS classes: Standard CSS classes will be developed by the developer in order to ensure that the advanced components of the user interface can be designed.
CSS frameworks are described in the form of a button. This is because the screen reader is unable to have a visual take on the control, on the website. Therefore, such a screen reader will have to do it aurally. This can be done only if the developers make use of the correct code with the correct semantics. This is what the CSS framework takes care of.
Let us see how CSS frameworks lead to greater accessibility.
A screen reader like Voice Over in Mac basically forms the connection between the web page and the user. The CSS framework comes with an accessibility tree. VoiceOver here makes use of this accessibility tree to communicate with the user what all information has been gathered about and from the site.
The Swiss Cheese model is a structure of accident causation. In this model, the aim is to separate the risk from the reality. The threat of a risk turning into reality is eliminated by the use of layers of protection and defense, one placed behind another. This is the same model followed by CSS frameworks. In this case, we have a button and a button description. In order to ensure that the button is described properly, there are several layers of protection undertaken, much like the Swiss Cheese model. These layers include code reviews, accessibility checkers and manual testing. These form the different slices of Swiss Cheese, placed one behind the other.
All this while, we have mainly focused on the use of proper semantics in CSS frameworks. But now, we learn that every element in this framework comes with a particular state. The complete description of the component includes the state. For instance, a checked checkbox is a state of an element. This leads to a more accessible and convenient framework in CSS.
ARIA includes more number of roles into the CSS framework, more than just the buttons. Each of these comes with a set of states and properties which gives rise to a number of user interface controls.
A set of tabs on the web page can allow the user to swap out of the visible panel. This mainly facilitates two or more control panels to be functioning together.
With this, and a lot more to offer, it is correct to say that CSS frameworks do offer greater accessibility. What are your views on this?
