Styling the input fields

In this example I am using Firefox, but you can do the same with any browser.

Right-click the field and click Inspect. This will open the browser’s Web Inspector.

In the Inspector you can see which CSS classes are being used for the element you inspected.

The Web Inspector also has a button in the toolbar that you can use to hover over and click anything on the page which will highlight it in the Inspector. From there, you can see the CSS classes that are being used.

Once you know the CSS classes, you can use them in your own CSS to modify the way the form looks.

Thank you for this detailed answer !!! This way I know that I was on the right track in my past attempts.

I have entered the following examples into the style.css of my divi-child theme:

.glsr input {
background: green;
}

site-reviews-title-glsr_abd209fe {
background: green;
}

Unfortunately, the background color of the input fields/the input field does not change. Is the problem 50 cm in front of my computer? … do I have to go to the optician ?

You are probably having issues due to CSS specificity. What is the URL?

https://www.tagespflege-rasselbande.de/home/

At the bottom of the page. Page looks bit confused because it’s in progress.

Of course I meant with #:

#site-reviews-title-glsr_abd209fe {

background: green;

}

Try this:

.glsr-form .glsr-input,
.glsr-form .glsr-textarea{
    background-color: #B2D4CC;
    border-radius: 10px;
}

I put in your code into style.css of Divi Child Theme:

.glsr-form .glsr-input,
.glsr-form .glsr-textarea{
border-radius: 10px;
background-color: #B2D4CC;
}

I cleared Cache of Divi (Theme Options > Builder > Advanced > Static CSS File Generation > ‘CLEAR’ … and saved it)
I cleared the Browser Cache of Microsoft Edge
I loaded the page ‘https://www.tagespflege-rasselbande.de/home/’ with Edge –> Radius and backround didn’t change ??

I installed Firefox and loaded the page ‘https://www.tagespflege-rasselbande.de/home/’ in Firefox –> Radius and backround didn’t change ??

Did you try to create your own example? … embed the shortcode in a divi text module and tried to make adjustments ?

.glsr-divi .glsr-input,
.glsr-divi .glsr-textarea {
    background-color: #B2D4CC;
    border-radius: 10px;
}

Thank you so much, that works fine.

Your support is really great. So my ￡30 donation a few days ago was a good investment !
