Solution retrospective


During the implementation of the project, I encountered a problem, namely the vertical centering of the element relative to the entire page.

I'm not sure I chose a good solution. I wrapped the main element in a container, for which I set the following values:

   position: fixed;
   top: 0;
   bottom: 0;
   right: 0;
   left: 0;
   display: flex;
   justify-content: center;
   align-items: center;

After that, the main element was centered vertically.

    Hi!

    You did a very good job on this project. I have some suggestions:

    To center this element both vertically and horizontally you can make use of the body tag. Just set the height of body to 100vh (100vh is 100% of the viewport height), and use flex.

    Also, remember to add alt attribute to your images. It's very important for screen readers.

    Hello there 👋. Good job on completing the challenge !

    I have some feedback for you if you want to improve your code.

    • To center an element vertically, you should use a height to its container. In this case it is recommended to use "min-height: 100vh" so that it occupies 100% of the viewport height. e.g.:
    .container-main {
        /* position: fixed; */
        /* top: 0; */
        /* bottom: 0; */
        /* right: 0; */
        /* left: 0; */
        display: flex;
        justify-content: center;
        align-items: center;
        min-height: 100vh;
    }
    

    HTML 📄:

    • The <div> tag defines a division or section on a website. It is used to style a container with CSS, set special alignment, or position content. It might be more efficient to use the <p> tag; the <p> element represents paragraph-level content, usually text:
    <p>A floral, solar and voluptuous interpretation composed by Olivier Polge, Perfumer-Creator for the House of CHANEL.</p>
    
    • The <h1> is the most important heading on the page, In this challenge the perfumer's name can be considered like the title of the page, so it should be the <h1>
    • You could use the <del> tag to indicate the price that was before the discount. Additionally, you can use a sr-only class to describe the discount. This will help screen reader users to understand that the price was discounted.

      Example: <del><span class="sr-only">Old price: </span>$169.99</del>

    • The alt attribute is used to provide a text description of the image which is useful for screen reader users, assistive technology users, and search engine optimization. Add the alt attribute to the <img> tag of the product.

    CSS 🎨:

    • Instead of using pixels in font-size, use relative units like em or rem. The font-size in absolute units like pixels does not scale with the user's browser settings. This can cause accessibility issues for users who have set their browser to use a larger font size. You can read more about this here 📘.

    I hope you find it useful! 😄 Above all, the solution you submitted is great!

    Happy coding!

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.
