    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.

    You’re doing fantastic! I hope these tips help you as you continue your coding journey. Stay curious and keep experimenting—every challenge is an opportunity to learn. Have fun, and keep coding with confidence! 🌟

    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;

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.
