We want you to add functionality to our page.

We want you to add functionality to our page. The header of the site should be fixed on the home page. The site header should always stay at the top of the page when the site page scrolls down. All code should be executed on 1 page. Comments should be available in every block. To make sure we understand each other, we broke the page into several blocks. BLOCK 2 1. Add to block-2 (you can see it in [login to view URL]) a "Select file" photo upload button in .jpg, .jpeg, .png, .webp, or .bmp format. When you click on the button "Select file", the user should be automatically redirected to the photo gallery of the phone (or PC), but not to the download folder. 2. The style of the "Select file" button must be the same as that of the other buttons on the page. 3. The user should be able to upload a file of any size (image resolution), and the file size should be limited to 30 mb. 3.1) The image itself, when uploaded to the site, should not climb out of the page template, regardless of whether the user looks at the page from a phone or a PC. 3.2) After loading the image the user must see a preview of the uploaded image. ([login to view URL]). 4. After the photo is loaded the button "verify now" must become active and change its color from gray to blue (Example of work on image [login to view URL]) BLOCK 3 4. After you click on the button "verify now" the block <div class="loading2"> should work, which simulates the checking of the file. (you can see it works in [login to view URL]). We don't need the real file check at the moment. BLOCK 4 5. After checking the file, you need to show a separate block with categories of several products. Each product card should contain: - A picture of the product - Description of the product - The button "Complete Order" under each item. An example you can see in the image [login to view URL]
