Bug: Modal Looses Backdrop Transition After Build

by ADMIN 50 views

Introduction

The modal component in DaisyUI is a crucial element for creating interactive and engaging user experiences. However, a recent issue has been reported where the modal loses its backdrop transition after building. This problem can be frustrating for developers, especially when it affects the overall user experience. In this article, we will delve into the details of this issue, explore the possible causes, and provide a solution to resolve the problem.

Reproduction URL and Environment

The issue can be reproduced on the official DaisyUI documentation website, specifically on the modal component page. The problem is present in version 5.0.0 of DaisyUI, and it has been tested on Chrome browser. The modal component still works properly in version 4, and it has been tested locally as well.

Description of the Issue

The issue arises when the modal component is built, and the backdrop transition is lost. The transition is a crucial aspect of the modal component, as it provides a smooth and visually appealing way to display the modal content. The transition is defined in the CSS code, specifically in the &:not(dialog:not(.modal-open)), &::backdrop block.

Before and After Code Comparison

To understand the issue better, let's compare the before and after code. The before code is as follows:

&:not(dialog:not(.modal-open)), &::backdrop {
  opacity: 100%;
  @starting-style {
    visibility: hidden;
  }
  @starting-style {
    opacity: 0%;
  }
  background-color: oklch(0% 0 0/ 0.4);
  transition: display 0.3s ease-out allow-discrete, opacity 0.3s ease-out, visibility 0.3s ease-out allow-discrete;
}

The after code is as follows:

.modal:not(dialog: not(.modal-open)), .modal::backdrop {
  opacity: 1;
  transition: display .3s ease-out allow-discrete, opacity .3s ease-out, visibility .3s ease-out allow-discrete;
  background-color: #0006
}

@starting-style {
  .modal:not(dialog: not(.modal-open)) {
    visibility: hidden
  }
}

@starting-style {
  .modal:not(dialog: not(.modal-open)) {
    opacity: 0
  }
}

As we can see, the after code has removed the opacity: 100% property and replaced it with opacity: 1. Additionally, the background-color property has been changed to #0006.

Possible Causes

Based on the code comparison, it appears that the issue is caused by the removal of the opacity: 100% property and the change in the background-color property. The opacity: 100% property is responsible for setting the initial opacity of the backdrop to 100%, which allows the transition to work properly. The change in the background-color property may also be contributing to the issue.

Solution

To resolve the issue, we need to restore the opacity: 100% property and change the background-color property back to its original value. We can do this by modifying the after code as follows:

.modal:not(dialog: not(.modal-open)), .modal::backdrop {
  opacity: 100%;
  transition: display 0.3s ease-out allow-discrete, opacity 0.3s ease-out, visibility 0.3s ease-out allow-discrete;
  background-color: oklch(0% 0 0/ 0.4);
}

@starting-style {
  .modal:not(dialog: not(.modal-open)) {
    visibility: hidden
  }
}

@starting-style {
  .modal:not(dialog: not(.modal-open)) {
    opacity: 0
  }
}

By making these changes, we can restore the backdrop transition and ensure that the modal component works properly.

Conclusion

Introduction

In our previous article, we explored the issue of the modal component in DaisyUI losing its backdrop transition after building. We also provided a solution to resolve the problem. In this article, we will answer some frequently asked questions related to this issue.

Q: What is the cause of the issue?

A: The issue is caused by the removal of the opacity: 100% property and the change in the background-color property in the after code.

Q: What is the effect of changing the background-color property?

A: Changing the background-color property to #0006 may also contribute to the issue, as it may not be compatible with the original value of oklch(0% 0 0/ 0.4).

Q: How can I resolve the issue?

A: To resolve the issue, you can modify the after code to restore the opacity: 100% property and change the background-color property back to its original value.

Q: What are the benefits of restoring the opacity: 100% property?

A: Restoring the opacity: 100% property will allow the transition to work properly, ensuring that the modal component works as expected.

Q: Can I use a different value for the background-color property?

A: Yes, you can use a different value for the background-color property, but make sure it is compatible with the original value of oklch(0% 0 0/ 0.4).

Q: How can I prevent this issue from occurring in the future?

A: To prevent this issue from occurring in the future, make sure to test your code thoroughly and avoid making changes to the opacity and background-color properties without understanding their impact.

Q: Is this issue specific to DaisyUI?

A: No, this issue is not specific to DaisyUI. It can occur in any CSS framework or library that uses a similar approach to modal components.

Q: Can I get help with resolving this issue?
