Responsive QR Code with plain HTML and CSS

neat and really professional.

Amazing job with this! You’re making fantastic progress. Here are some small tweaks that might take your solution to the next level…

• I think you could benefit from a plugin on VS code called Prettier, It will format your code make it more easily readable.

• 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.

• Line height is usually unitless to scale proportionally with the font size, keeping text readable across different devices. Best practice is to use a unitless value like 1.5 for flexibility. Avoid using fixed units like px or %, as they don't adapt well to changes in font size or layout.

• Using rem or em units in @media queries is better than px because they are relative units that adapt to user settings, like their preferred font size. This makes your design more responsive and accessible, ensuring it looks good on different devices and respects user preferences.

• For future project, You could download and host your own fonts using @font-face improves website performance by reducing external requests, provides more control over font usage, ensures consistency across browsers, enhances offline availability, and avoids potential issues if third-party font services become unavailable.

Hi!

I have liked your solution. There are some things that I have not thought about. I am a newbie, but there is one thing I have noticed, the variable's name should not be linked to the value but yes to the function.

E.g.: highlight-color: #4fb9ff;, instead light-blue: #4fb9ff;

• Design is very better than me.
• No readme file and no live webpage.
