    Hi Abdoulaye

    I took a look at your code and found a few things you could adjust.

    you have given the img element a height and width of 180px. This would be unresponsive if necessary and would not adjust to its parent element. You could fix this by giving the container a max-width of the desired width and the width: 100%;. The img should also have the property width 100%.

    for web accessibility you should add a <main role="main>" and nest your code in it. Also you should change your h3 element to an h1 element. this is also important for this case. You can take a look at google and see what is important for web accessibility.

    try to use rem instead of px for the font size. if necessary the font's wouldn't adjust to the brower size with px.

    Keep coding and have a great day

    Replace<div class="container">with the main tag, <h3> with <h1> and <div class="attribution"> with the footer tag to fix the accessibility issues. click here for more on web-accessibility and semantic html

    wrap " Scan the QR code to visit Frontend Mentor and take your coding skills to the next level" in a <p> . e.g: <p> Scan the QR code to visit Frontend Mentor and take your coding skills to the next level</p>

    Use the colors that were given in the styleguide.md found in the zip folder you downloaded

    Give .container a fixed width value, for a responsive content, give .container a fixed max-width value. eg: width:320px Give p and h1 the same padding left and padding right value , the same margin-top value and a text-align: center.

    Give the img a max-width of 00% instead of a width and height value in an inline css.

    To center .container on the page, add min-height:100vh; display: flex; align-items: center: justify-content: center; or min-height:100vh; display: grid place-items: center to the body.

    To center .container on the page using flexbox:
    body{
    min-height: 100vh;
    display: flex;
    align-items: center;
    justify-content: center;
    }
    
    To center .container on the page using grid:
    body{
    min-height: 100vh;
    display: grid;
    place-items: center;
    }
    

    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

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.
