Product page using flex in css

Hey @sujeong054,

Nice job on finishing this challenge! It looks really good and you made good use of Flexbox. To answer your question:

body {
  display: grid;
  place-items: center;
  min-height: 100vh;
}

With these three CSS properties, you can center everything within your body to the center. min-height: 100vh is important because it makes the body as big as your browser viewport. Without that line, the body always takes up only the space of its children, so you won't get the effect.

With the above, you can reduce your CSS on the .main element:

.main {
  display: flex;
  background-color: var(--White);
  border-radius: 15px;
  height: 650px;
}

Besides that, a couple of additional suggestions:

• Try to use more semantic HTML elements. As the accessibility report already indicates, your page should have at least one main landmark, meaning that you should wrap your application in a main element. You can replace the div.main with a main.main to make that work.
• The page is also missing a title. You've used a lot of div and span elements for the text content, which don't convey any semantic meaning. Screen readers and search engines will have trouble understanding what's the product title, its category, or description. I'd recommend the following HTML structure:

<p>Perfume</p>
<h1>Gabrielle Essence Eau De Parfum </h1>
<p>A floral, solar and voluptuous interpretation composed by Olivier Polge, Perfumer-Creator for the House of CHANEL.</p>
<div>
  <p><span class="sr-only">Current price:</span>$149.99</p>
  <p><span class="sr-only">Old price:</span>$169.99</p>
</div>
<button type="button">Add to Card</button>

• With the above code, you get an h1 as the page title and a p for the description. From a perspective of accessibility, the pricing section a bit challenging - while we can visually indicate that the price is reduced, we have to explain it to those who can't see. I included span elements for that, made invisible via the .sr-only class. If you want to learn more about this technique, here's a great explanation.
• All interactive elements like buttons or links should have some hover and focus styles. Your button lacks these, making it unclear whether it's clickable or not. You could change the background color on hover to be darker or brighter, just as an idea.

Hope this answers your question and gives you some help. Let me know if you have any questions :-)
