Enhancing Button Interaction with Tab Navigation

In web development, providing a smooth and intuitive user experience is essential. When users navigate through a web page using the tab key, it’s beneficial to provide visual cues to indicate which element currently has focus.

Solution:

This can be achieved by adding a hover effect to buttons when they receive focus during tab navigation. The code snippet you provided demonstrates a simple implementation using jQuery to add and remove a CSS class for the desired hover effect.

JQuery:
$('#card-btn').on('focus', function () {
        $(this).addClass('hovered');
});
$('#card-btn').on('blur', function () {
        $(this).removeClass('hovered');
});

CSS:
#card-btn.hovered {
     background-color: rgba(40, 116, 52, 0.9);
}

The code snippet you provided aims to add a hover effect to buttons when they receive focus during tab navigation.

• The code attaches event handlers to the button with the ID `#card-btn` to trigger the hover effect when they receive focus. The `focus` event is used to add a CSS class called `’hovered’` to the respective button elements.
• Similarly, the code attaches event handlers to the same buttons using the `blur` event. The purpose of these handlers is to remove the `’hovered’` CSS class from the buttons when they lose focus.
• The `’hovered’` CSS class is responsible for applying the desired hover effect to the buttons. The exact styling rules for this class would need to be defined in the CSS file or inline styles. These styles can include changes to the background colour, text colour, border, or any other visual properties to indicate the hover state.
