Solution retrospective

What are you most proud of, and what would you do differently next time?

I am proud of how I was able to keep the QR code and it's content in the middle of the webpage. This CSS code:

    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);```

I hope to make use of bootstrap and design the webpage to be more interactive next time.

### What challenges did you encounter, and how did you overcome them?
I encountered challenges such as;
1. How to make the div and image stay in the middle.
2. How to curve around the edges of the scanner image.
3. The texts were warping and the image shrinking while I resized the window.

How I overcame the above challenges(respectively);
1. I checked different resources and was able to use the `top`, `bottom` and `transform:translate(-50%, -50)` to keep the div and the image at the center.
2. I simply used the CSS: `border-radius` on the `img` element.
3. I found out the warping texts and shrinking QR code image were simply because I used `max-width` for my contents, so any size of the page, it had to readjust. As soon as I changed it to `width`, everything was settled!

### What specific areas of your project would you like help with?
1. I wasn't able to use the specific sizes given in the `style-guide.md`. How was I supposed to use those sizes?

Exceptional work! You’re showing great skill here. I’ve got a couple of minor suggestions that could make this stand out even more…
- Avoid using id selectors for styling in CSS because they are too specific and hard to override, making your styles less flexible and maintainable. Instead, use class selectors (.), which are reusable and more manageable, allowing for better control over your styles and easier updates.
- Using a <main> tag inside the <body> of your HTML is a best practice because it clearly identifies the main content of your page. This helps with accessibility and improves how search engines understand your content.
- Every page should have one <h1> tag,
- Using a full modern CSS reset is beneficial because it removes default browser styling, creating a consistent starting point for your design across all browsers. It helps avoid unexpected layout issues and makes your styles more predictable, ensuring a uniform appearance on different devices and platforms, check out this site for a Full modern reset
- While px is useful for precise, fixed sizing, such as border-width, border-radius, inline-padding, and <img> sizes, it has limitations. Pixels don't scale well with user settings or adapt to different devices, which can negatively impact accessibility and responsiveness. For example, using px for font sizes can make text harder to read on some screens, Check this article why font-size must NEVER be in pixels. In contrast, relative units like rem and adjust based on the user’s preferences and device settings, making your design more flexible and accessible. Use px where exact sizing is needed, but prefer relative units for scalable layouts. If you want a deeper explanation watch this video by Kevin Powell CSS em and rem explained. Another great resource I found useful is this px to rem converter based on the default font-size of 16 pixel.
- Using position: absolute is not always best practice because it removes elements from the normal document flow, making layouts harder to manage and potentially causing overlap or misalignment on different screen sizes. Instead, use flexible layout techniques like CSS Grid or Flexbox for more responsive and maintainable designs.
- Using margin-inline: auto is better than margin: auto for centering elements horizontally because it is more precise. To center an element, set its width and apply margin-inline: auto; this will center it within its container., You can center the height by using this code snippet
```
  min-height: 100svh;
  display: flex;
  justify-content: center;
  flex-direction: column;
  align-items: center;
```
I hope you’re finding this guidance useful! Keep refining your skills and tackling new challenges with confidence. You’re making great progress—stay motivated and keep coding with enthusiasm! 💻
