Multilingual Website and Mobile version of the website

Site URL: https://www.skill-up.nu/

Hi!

1- We have created a website that has Dutch as the main language and English as a second language. We would like to make it possible for people on the dutch pages to be directed to the contact form in dutch when pressing the “contact” button on the header and vice versa for the English page. 
Could someone please help us achieve that? 

I have tried using previously shared codes however, I always get a syntax error :( 
2- On the Dutch version of our contact form, under the name space I can’t alter the text “First name” and “Last name”, I would like this to be in Dutch. Does someone know a solution?

3- I used this code to resize my logos on the “home” page and wanted to use it again for the images on the “about us'' page. But that doesn’t work, how can I use the same code twice? I want to resize the image only on the mobile version of the website, where they are too small. 
@media only screen and (max-width:640px){.sqs-block-image{width:40%;margin: auto}}

Any help or suggestions will be very appreciated!

I think @creedon solved some similar questions.

I may be able to help with item one.

Please see the following.

You'll need to install the script before the language code. Otherwise the language code won't be able to do it's magic to the buttons.

Then to the language code add the following below the /* ADD LANGUAGE CLASSES */ section of code.

$('.header-actions-action--cta a:link:not([href^="http://"]):not([href^="https://"])').each(function () {
      var langType = $(this).attr('href').split("/")[1];
      var multiLanguageClass = 'multilanguage lang-' + langType + '';
      if (undefined !== langType && langType.length <= 2) 
        $(this).addClass(multiLanguageClass).parent().addClass(multiLanguageClass);
    });

So this...

    });

    /* HOMEPAGE-LOGO LINKS TO PROPER LANGUAGE HOMEPAGE */

...becomes...

    });
    $('.header-actions-action--cta a:link:not([href^="http://"]):not([href^="https://"])').each(function () {
      var langType = $(this).attr('href').split("/")[1];
      var multiLanguageClass = 'multilanguage lang-' + langType + '';
      if (undefined !== langType && langType.length <= 2) 
        $(this).addClass(multiLanguageClass).parent().addClass(multiLanguageClass);
    });

    /* HOMEPAGE-LOGO LINKS TO PROPER LANGUAGE HOMEPAGE */

Let us know how it goes.
