Your pages look good @vanoushka18. Some things to revisit;
prod landing
Codepen provides the boilerplate for you. It only expects the code you’d put within the body element in the HTML editor. (No need to include the body tags). For anything you want to add to the <head> element click on the ‘Settings’ button, then HTML and add it into the ‘Stuff for <head>’ box.
For instance links to fonts go in the box labeled ‘Stuff for <head>’
You have elements out of order. Everything the browser displays belongs on the body element. Review this for an understanding of the HTML boilerplate tags.
There are HTML syntax/coding errors you should be aware of and address.
Codepen provides validators for HTML, CSS and JS. Click on the chevron in the upper right of each section and then click on the respective ‘Analyze’ link.
The one for CSS is good. Use it and address the issue(s). (You may have to run it more than once)
(The one for HTML misses things which is why I recommend W3C)
Do not use the <br> element to force line breaks or spacing. That’s what CSS is for.
Do not use view port units for font sizes. The user should always be in control of the text size on the page (that is, they should be able to manually increase the text size). Using view port units prevents them from doing this. Your job as a developer is to make sure your page is responsive to text size increases. If you don’t know how to manually increase the text size, using Firefox, go to the ‘View->Zoom’ menu and activate ‘Zoom Text Only’. Then while holding down the Ctrl key scroll your middle mouse button to increase the text size. If font-sizes are defined with vw units the only way a user can increase the text size is to widen the browser window. What if the user has really bad eyesight and can’t make the browser window wide enough?
tech doc
All of the same issues noted above also appear here.
In addition;
Writing this <p><code></code></p> to pass a user story is not the best way to show your coding ability.
In programming circles, you’ll see a lot of conversation about (technical) documentation, in reference to explaining an API, library, project contribution, etc. Reading and writing good documentation is an important skill and doing this project about a code related subject gives you a good reason to go do some research about the tools you are learning to use.
