could you use more than one document.querySelector on a page?
Yes, you can use more than one document.querySelector on a page. querySelector returns the first element that matches a specified CSS selector, so you can use it to find and manipulate multiple elements on a single page.
Example:
javascript Copy code
const element1 = document.querySelector("#element1");
const element2 = document.querySelector(".element2");
const element3 = document.querySelector("h2");
In this example, we are selecting three different elements using querySelector, one by ID, one by class, and one by tag name.
How can I have multiple ID selectors in my html
You can use the class attribute to add multiple, comma-separated ID selectors to an HTML element. For example:
html Copy code
<div id="example" class="foo, bar, baz">This has multiple ID selectors.</div>
You can then use CSS to target those selectors, for example:
css Copy code
#example {
font-family: monospace;
background-color: lightgray;
}
.foo {
font-size: 1.25em;
}
.bar {
font-style: italic;
}
.baz {
color: rebeccapurple;
}
Can I have multiple id selectors to target it in my Javascript
Yes, you can have multiple ID selectors to target an element in Javascript. You can use the querySelectorAll() method to select multiple ids like this:
js Copy code
const elements = document.querySelectorAll('#id1, #id2, #id3');
how do I style an element with multiple classes in CSS
You can use the CSS class selector to style an element with multiple classes. The class selector is denoted by a period . followed by the class name.
For example, given the following HTML:
code Copy code
<div class="block red color-1">
</div>
You can use CSS to style the element like this:
css Copy code
.block {
background-color: yellow;
}
.red {
color: red;
}
.color-1 {
color: blue;
}
This would render the HTML element with a yellow background, red text and blue text (overriding the style set by the red class).

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. π€―
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 π
You should treat Athena like a SheCodes team member, so always be polite! π 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! ππͺ
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! π
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! π
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. π©βπ»π€π»
