HTML, CSS, JavaScript

Hi, Nice work. There are some section need to improve.

• If you want you can use a library named http://flexboxgrid.com/ to make you site responsive.
• There are so many white space. Please try to reduce this.
• Use main for this section name. Now you are using <section id="menu">
• Try to use class not id. Using class you can use it many times but id is using for single time

Happy coding. Hope that this will helpful for you.

Greetings.

• well done , your site is responsive.
• You have created a custom hamburger using divs and spans which is awesome but then you have to look into wai-aria attributes to allow people who rely on assistive technology to use your site. And that goes again to the closing menu button
• Do not use more than one h1 element per page ,it does not cause errors but is considered bad practice, see this article for more information headings
• Check also the following article on responsive images. The method you used below is not recommended. Read about srcset and picture element

<img src="assets/image-transform.jpg" alt="" width="50%" class="laptop-design-img">
            <img src="assets/mobile/image-transform.jpg" alt="" class="mobile-design-img">
