How to select parent pseudo-class from within child using scss

由 ╄→гoц情女王★ 提交于 2021-01-21 09:16:30
问题 I'd like to select the parent using the following pattern. I understand I could write this within the parent selector, but I'd like to know if it's possible to prefix the parent's pseudo class to the child from within the child selector. JSX: <div class="parent"> <div class="child" /> </div> <div class="parent"> <div class="child" /> </div> SCSS: .parent { height: 100px; .child { // the goal is to write this so it produces the CSS output below, from // within .child &:first-child & { height:

Python a &= b meaning?

问题 What does the &= operator mean in Python, and can you give me a working example? I am trying to understand the __iand__ operator. I just don't know what &= means and have looked online but couldn't find it. 回答1: Explanation Understandable that you can't find much reference on it. I find it hard to get references on this too, but they exist. The i in iand means in-place , so it's the in-place operator for & . &= calls the __iand__ operator, if it is implemented. If not implemented, it is the

Hyperlink href incorrectly quoted in innerHTML?

问题 Take this very simple example HTML: <html> <body>This is okay & fine, but the encoding of <a href="http://example.com?a=1&b=2">this link</a> seems wrong.</body> <html> On examining document.body.innerHTML (e.g. in the browser's JS console, in JS itself, etc.), this is the value I see: This is okay & fine, but the encoding of <a href="http://example.com?a=1&b=2">this link</a> seems wrong. This behaviour is the same across browsers but I can't understand it, it seems wrong. Specifically, the

Running bash script does not return to terminal when using ampersand (&) to run a subprocess in the background

由 北城余情 提交于 2020-03-13 06:11:02
问题 I have a script (lets call it parent.sh) that makes 2 calls to a second script (child.sh) that runs a java process. The child.sh scripts are run in the background by placing an & at the end of the line in parent.sh. However, when i run parent.sh, i need to press Ctrl+C to return to the terminal screen. What is the reason for this? Is it something to do with the fact that the child.sh processes are running under the parent.sh process. So the parent.sh doesn't die until the childs do? parent.sh

What is the purpose of `&` before the loop variable?

问题 What is the purpose of & in the code &i in list ? If I remove the & , it produces an error in largest = i , since they have mismatched types (where i is &32 and i is i32 ). But how does &i convert i into i32 ? fn largest(list: &[i32]) -> i32 { println!("{:?}", list); let mut largest = list[0]; for &i in list { if i > largest { largest = i; } } largest } fn main() { let hey = vec![1, 3, 2, 6, 90, 67, 788, 12, 34, 54, 32]; println!("The largest number is: {}", largest(&hey)); } Playground It
