Making an attempt out native dialog modals



I wrote an post on producing your modal rather of applying a plugin.

I reposted it the other day on Twitter, and Jhey produced a superior comment that it could swiftly be carried out with the dialog component these days.

I built a Astro model run by dialog but haven’t prepared down the plain variation for you all.
So in this write-up, we’ll build a modal with the dialog factor.

The dialog aspect

The major ingredient we are going to be functioning with right now is the dialog component.
This is an HTML factor that, by default, is a dialog (not a modal).

It can get an open up state, indicating whether or not it truly is open up or not.


Hello there from the dialog

Enter fullscreen mode

Exit fullscreen method

The code higher than will render the dialog specifically on our page like this.

Dialog in HTML

You can expect to notice that it is really not a modal and won’t have a backdrop this way.

Dynamically opening the modal

We normally want to open up the dialog with some action.

Luckily for us, the dialog comes with a JavaScript API.
If you give your dialogs a particular ID, we can goal them.


Howdy I only exhibit on click on

Enter fullscreen method

Exit fullscreen method

We can then use JavaScript to open up the modal like this.

window.mydialog.clearly show()
Enter fullscreen mode

Exit fullscreen manner

Even so, I might recommend making use of the extra express showModal functionality.
This just one makes it a modal, allowing for us to have a backdrop and centering the dialog on the web site.

Enter fullscreen method

Exit fullscreen method

It’s, of program, rather scarce to clearly show a dialog specifically in the browser so let’s only display it on button simply click.

 onclick="window.mydialog.showModal()">present modal


Hello there I only present on simply click

Enter fullscreen method

Exit fullscreen method

Closing the modal

There are two strategies of closing the modal. The initially a person is to use the close perform on the dialog like so:

<button onclick='window.mydialog.close()'>close modal</button>
Enter fullscreen mode

Exit fullscreen manner

Alternatively, you can use an HTML way of closing the dialog.
You can place a kind with the approach dialog inside the dialog aspect.


Enter fullscreen mode

Exit fullscreen mode

Styling the modal backdrop

The final aspect of why the dialog is cool is that you can design some tailor made features.

We get a new pseudo-element named ::backdrop to design and style the backdrop the modal has.

  track record: rgba(255, , , .1)

Enter fullscreen mode

Exit fullscreen manner

We need to now get a pinkish backdrop coloration when we open the modal.

Then, of class, you can fashion every single aspect of the dialog as you see healthy.

Accessibility problems

It’s excellent to note that to this working day, there are even now some accessibility considerations raised.

But from seeking it out, most browsers these days also obtained the comprehensive assist of the concentration in just the dialog, and it is searching to be a comprehensive-blown obtainable answer.

Read additional about the worries.


The dialog component, exposed APIs, and styling choices are a excellent way to make modals these times.

I’m sure to be hoping them out on a undertaking incredibly before long.

If you want to perform with the dialog component, I’ve established this CodePen for you to try out out.
