recently as I updated some SEO details on my website I saw that the preview for the gallery just went crazy, now when you click on a picture you are sent to the bottom of the page where the picture is showed in huge resolution and the control arrows are showed in the bottom left corner. Any ideea what went wrong here?
You load jQuery but you never use any jQuery code. You have both bootstrap 5.3.2 and bootstrap 4.3.1 on your pages.
The portfolio images on the index.html page should be lazy loaded, they don’t have an alt tag or width and height tags.
You can optimize the images to webp
Header elements are not in sequential descending order
Your contact form, name and email fields should have an autocomplete attribute
Your button to change language doesn’t have an aria-label attribute
In your language modal change the type of the buttons to links and set the href attribute to what you have in the data-url. Then you can remove the custom code block from your pages that load the jQuery, bootstrap 4.3.1, popper and the inline script
