I found it difficult to use the whole page in order to center the component.

    hi Andrew ..

    To center the component better . Here are some to changes I did after I downloaded your code .All my work was focused on the CSS code

    1.Index.html file remove line 33

    2.Index.html file line 48 > width:40% ;

    3 index.html add .container { height:50%}

    4.index.html set img{ width:70%; border-radius: 10px;height: 80%; }

    1. index.html line 65 add div > p { font-size: 0.8rem; line-height: 1.5; }

    6 .index.html line 93 replace the media query with this new media query

      @media screen and (min-width: 550px) {
    
    .container {height: max-content; width: 25%; }
    
     img {width:90%; border-radius: 10px; height: 30vh; }
    
      }

    I found this article to be very helpful on centering: https://css-tricks.com/centering-css-complete-guide/ For my solution, I followed the guideline under centering vertically & horizontally, with the element of being a fixed width and height.

    I'd extend the width of your qr component card so that the text flows better. I do like how the color of the footer complements the color scheme. Great job overall!

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.
