what does rem in css mean?
rem stands for "root em" and it is a relative unit of measurement in CSS. It is based on the font-size of the root element (typically the <html> tag).
Unlike the em unit, which is relative to its parent element, rem is always relative to the root element. This means that if the root element has a font-size of 16 pixels, then 1 rem is equal to 16 pixels.
The use of rem allows for more consistent and scalable designs, especially when it comes to responsive web development. Instead of specifying sizes using fixed pixels, rem can be used to create flexible and adaptable layouts.
Here's an example:
css Copy code
html {
font-size: 16px;
}
p {
font-size: 1.5rem; /* This would be equivalent to 24 pixels (1.5 * 16) */
}
With this example, even if the font-size of the root element changes, the p element will always be 1.5 times the size of the root element's font-size.
What is em
In computing, "em" is a unit of measurement that is commonly used in web design and typography. It is a relative unit and is typically used to define the size of text or other elements in relation to the font size of the parent element. For example, if the font size of a parent element is 16 pixels, then 1em would be equal to 16 pixels.
Here is an example of how em units can be used in CSS:
css Copy code
.parent {
font-size: 16px;
}
.child {
font-size: 1em; /* This will be 16 pixels */
}
.grandchild {
font-size: 0.75em; /* This will be 12 pixels (0.75 * 16) */
}

use em in html
To use em in HTML, you can apply the 'em' unit to your text. The 'em' unit is a relative unit of measurement that adjusts to the font size of the parent element. Here's an example:
html Copy code
<p>This text is <em>emphasized</em> using the em HTML tag.</p>
In the example above, the word "emphasized" is wrapped in an em tag to apply the emphasized styling. You can adjust the size of the emphasized text by setting font-size on the parent element.

AI stands for Artificial Intelligence. AI bots are able to learn from conversations with users and expand their knowledge this way.
SheCodes Athena will help you with technical questions about your code using artificial intelligence to find the answer. Imagine a super powerful human who has memorized everything on the internet and can access that knowledge in a matter of seconds. 🤯
SheCodes Athena can answer most coding-related questions, even complicated ones! It can even find bugs in your code and tell you how to fix them in just a few seconds. Impressive, right?
Just remember we're still in testing mode so the AI may return strange or incorrect replies. Feel free to message us if this happens!
SheCodes Athena can only reply to coding-related technical questions. The same type of questions you would ask in the channels on Slack.
For questions that are not coding-related, write us here 😃
You should treat Athena like a SheCodes team member, so always be polite! 😊 Ask your questions as detailed as possible, just like you would do on Slack.
Here are some examples:
- Prettier isn't working on my VS Code. How do I fix this?
- How do I make bullet points with different colors using the list element?
- My code in Codesandbox is having some issues. Can you please tell me what the issue is? [Include the link to your Codesandbox]
For now, SheCodes Athena is limited to 5 questions per day for each student.
In that case, you can either ask SheCodes Athena a follow-up question, or you can post on the designated weekly channel on Slack!
Our technical assistants are still available on Slack and are always happy to help! 😍💪
Remember, questions are limited to 1000 characters.
- If you're working with an HTML file: Post a snippet of your code related to the issue you're having (just copy the code and paste it into the question box).
- If you're working with Codesandbox: Good news, you can just post the link to your Codesandbox and the AI Assistant will be able to view your code.
- If you have a longer question that would require an entire HTML file or more than 1000 characters, post it in the designated weekly channels on Slack! 😃
Athena was the Greek goddess of wisdom, among other elements. She received her name from the city of Athens, which she is known for protecting.
Much like the goddess Athena, SheCodes Athena is also incredibly wise and can solve complicated coding puzzles in a matter of seconds! 😍
Not likely. AI can automate tasks and make developers' jobs more efficient but it can't fully replace the human ability to deal with complex software. And AI will still require human developers to supervise and improve it further.
So developers may see their tasks change but they won't be replaced by AI. 👩💻🤝💻
