Problem

if I have `flex` and `hidden` in one class the `flex` class seems to overide the `hidden` class. I feel the `hidden` class should have higher importance Here is a fiddle link: https://jsfiddle.net/338mbbr5/1/ [code block]

Adjust CSS Specificity for Flex and Hidden Classes

Medium Risk

In CSS, the specificity of a class determines which styles are applied when multiple classes are used on the same element. The Tailwind CSS 'flex' class has a higher specificity than the 'hidden' class, causing the 'hidden' class to be overridden. This is due to the way CSS applies styles based on specificity rules, where more specific selectors take precedence.

  1. 1

    Create a Custom CSS Class

    Define a custom CSS class that combines the properties of both 'flex' and 'hidden' to ensure that the element can be hidden while maintaining the flex properties when needed.

    css
    .flex-hidden { display: none; }
  2. 2

    Apply Custom Class Conditionally

    Use JavaScript or a conditional rendering approach to apply the 'flex-hidden' class when you want the element to be hidden, while still allowing the 'flex' class to be applied when the element should be displayed.

    javascript
    const element = document.getElementById('yourElementId');
if (shouldHide) {
  element.classList.add('flex-hidden');
} else {
  element.classList.remove('flex-hidden');
  element.classList.add('flex');
}
  3. 3

    Remove Conflicting Classes

    Ensure that the 'hidden' class is not applied simultaneously with the 'flex' class to prevent conflicts. Instead, manage visibility through the custom class created in step 1.

    javascript
    element.classList.remove('hidden'); // Ensure 'hidden' is not applied
  4. 4

    Test Visibility Functionality

    Test the implementation by toggling the visibility of the element to ensure that it hides and shows correctly without conflicts between 'flex' and 'hidden'.

    javascript
    console.log(element.classList); // Check applied classes

Validation

Confirm the fix by checking that the element can be hidden and shown correctly without any display issues. Use browser developer tools to inspect the element and verify that the 'flex-hidden' class is applied when it should be hidden.
