White font on white background

In source file: forms-booking-reservation.html the text in "Select Persons" is white on white background, how to fix it?

How many requests per minute can form.php process on a simple VPS?

Please tell me where the fields of the letter are edited

)))

1. This is a Firefox Bug. Consider adding the .form-select Class to the <select> Element.

• I am using google chrome, but that helped fix the error.

1. To change the Language of the Field Names, you will need to Translate this in the Form’s HTML Code itself. Simply find the following code in your Form’s HTML Codes: name="template-contactform-name" and replace the name with your Translated Text. Example: name="template-contactform-nombre" .

This will display as Nombre in the Form Response Email.

• Sorry, no changes(((

Codes: name=”template-contactform-name”
Will this field accept Russian text?

Codes: name=”template-contactform-количество-гостей”

1. Yes, this should be Phone. Can you please consider trying this again? And yes you can use any Language.

• Hi! Everything is working. Most likely the old code was in the cache

I still have a lot of questions about this form. I hope I don’t bother you ...

1. This piece of code is responsible for displaying the date in this form forms-booking-reservation.html

jQuery(document)
                       $('.travel-date-group').datepicker({
				autoclose: true,
				todayHighlight: true,
				startDate: "0 days",
				format: "mm/dd/yyyy"
			}).on('changeDate', function(){
				let dayCheckin = new Date( checkIn.prop('value') ),
					dayCheckout = new Date( checkOut.prop('value') ),
					nights = ( dayCheckout.getTime() - dayCheckin.getTime() ) / (1000 * 3600 * 24);
				$( ".time-value" ).html( nights + '' );
			});

When I change the format: "mm/dd/yyyy" on format: "dd/mm/yyyy", this block stops working (Screenshot_3).

2. You already understood that I do not know html very well. Could you explain to me how add the disabled attribute to the

   Забронировать
 

before data validation, so that false reports about the form submission are not added to the metric.

3. Why do mobile versions have such poor PageSpeed ​​Insights performance? No more than 50 points.

On this page I have inserted only a few of my photos, I have not changed the code ...

4. Loading = "lazy" does not work on this block (Screenshot_4) and in these sections:

  Is this how it should work?

Thank you for your patience!
