Client-side validation alone does not ensure security; therefore data needs to be validated on the server-side as well.Forms frequently include required input that needs to be clearly identified using labels.HTML5 input types are displayed as simple input fields in older web browsers that do not support these HTML5 features.The example below shows these HTML5 input types in action.These dialogs are expected to respect the settings and preferences of the user in the web browser (and operating system), such as default font-size, colors, and language.In the example below, the attribute is added to the input field.Depending on your web browser, the “Range” input field will be displayed as a slider control to help users provide input more easily.Similarly, the “Number” input field may be displayed with buttons to increase or decrease the number incrementally.
Client-side validation can also be easily bypassed, or the data is changed before reaching the server.If your web browser supports HTML5, it will not allow you to submit the form without entering text into the input field.Instead, it will display a message that is generated by the web browser itself.Where possible, require user confirmation for irreversible actions, such as permanent deletion of data.Examples include: These tutorials provide best-practice guidance on implementing accessibility in different situations.
