Solution retrospective


What are you most proud of, and what would you do differently next time?

I'm glad that I was able to complete this. I have learned that prior to getting into the coding there are many other challenges and sometimes command line things you need to learn. Finally, getting to practice has been great!

Next time, I would like to make the responsiveness more fluid.

What challenges did you encounter, and how did you overcome them?

Some of the challengers I encountered were getting the white background container centered. I was able to do it at some point but after editing the elements inside, it locked back to the left of the screen.

I later solved this with margin: auto; but I don't fully understand why it went back to the left hand side of the page.

What specific areas of your project would you like help with?

When I zoom in or out of the page the size of the text changes, but the image size does not change. I'm not sure if this is the correct approach to this. I think it breaks page.

I would like to learn how to handle that situation.

    To allow the design to scale when you zoom, make sure the width, padding and font-size properties are using REM units on all elements on the page (eg .qr-container { width: 25rem }).

    I would also add ARIA landmarks to the HMTL to help with accessibility (eg <main role="main"> around the .qr-container div and <footer role="contentinfo"> around the .disclaimer div).

How does the accessibility report work?

When a solution is submitted, we use axe-core to run an automated audit of your code.

This picks out common accessibility issues like not using semantic HTML and not having proper heading hierarchies, among others.

This automated audit is fairly surface level, so we encourage to you review the project and code in more detail with accessibility best practices in mind.

How does the CSS report work?

When a solution is submitted, we use stylelint to run an automated check on the CSS code.

We've added some of our own linting rules based on recommended best practices. These rules are prefixed with frontend-mentor/ which you'll see at the top of each issue in the report.

The report will audit all CSS, SCSS and Less files in your repository.

How does the HTML validation report work?

When a solution is submitted, we use html-validate to run an automated check on the HTML code.

The report picks out common HTML issues such as not using headings within section elements and incorrect nesting of elements, among others.

Note that the report can pick up “invalid” attributes, which some frameworks automatically add to the HTML. These attributes are crucial for how the frameworks function, although they’re technically not valid HTML. As such, some projects can show up with many HTML validation errors, which are benign and are a necessary part of the framework.

How does the JavaScript validation report work?

When a solution is submitted, we use eslint to run an automated check on the JavaScript code.

The report picks out common JavaScript issues such as not using semicolons and using var instead of let or const, among others.

The report will audit all JS and JSX files in your repository. We currently do not support Typescript or other frontend frameworks.
