Solution retrospective


Ok, second solution now. I have a just two specific questions now. 1- What does exactly the "min-height" do? I know that it's purpose is to put it on the middle of the page, but isn't that the job of the "align-items" property? Also what exactly is "hv" on "100hv". What kind of measurement is that? 2- The solution I gave still has the words in a different size than the challenge, even tho I've used the exactly same font size and weight, why is that?

    Replace <div class="box-2"> with the main tag to fix the accessibility issues. click here for more on web-accessibility and semantic html

    There is no need to style box-2, give the background-color you gave to .box-2 to the body.

    To center .box-1 on the page using flexbox or grid instead of margin, add min-height:100vh; display: flex; align-items: center: justify-content: center; or min-height:100vh; display: grid place-items: center to the body.

    USING FLEXBOX:
    body{
    min-height: 100vh;
    display: flex;
    align-items: center;
    justify-content: center;
    }
    
    USING GRID:
    body{
    min-height: 100vh;
    display: grid;
    place-items: center;
    }
    

    For a responsive content, replace the width in .box-1 with max-width and give the img a max-width of 100%.

    Replace the height in .card with a padding value for all the sides, this will prevent the content from overflowing on smaller screens and its a responsive replacement. padding:16px.

    Give h1 and p the same font-size of 15px which is 0.9375rem, text-align: center, the same margin-left, margin-right and margin-top values. Give p a margin bottom value.

    Use relative units like rem or em as unit for the padding, margin, width values and preferably rem for the font-size values, instead of using px which is an absolute unit. For more on CSS units Click here

    Hope am helpful.

    Well done for completing this challenge. HAPPY CODING

    Hello there 👋. You did a good job!

    I have some suggestions about your code that might interest you.

    HTML 📄:

    • Wrap the page's whole main content in the <main> tag.

    CSS🎨:

    You can use grid or flexbox to center the content no matter the viewport size. Using grid you can do the following:

    body {
    min-height: 100vh;
    display: grid;
    align-items: center;
    justify-content: center;
    }
    

    With flex:

    body {
    min-height: 100vh;
    display: flex;
    align-items: center;
    justify-content: center;
    }
    
    • Avoid using absolute length units px, especially for font-size and width properties, because they are not relative to anything else so that means they will always be the same size. Instead, you can use relative lengths like em or rem. The benefit of that last one is element which has that unit will scale relatively to everything else within the page, e.g., the parent container. You can dig up about it 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 1st-party linked stylesheets, and styles within <style> tags.

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.
