LESS - Parent Selectors
In this chapter, let us understand how Parent Selectors work. It is possible to reference the parent selector by using the &(ampersand) operator. Parent selectors of a nested rule is represented by the & operator and is used when applying a modifying class or pseudo class to an existing selector.
The following table shows the types of parent selector −
Sr.No. | Types & Description |
---|---|
1 | The & will represent the nearest selector and also all the parent selectors. |
2 | Prepending a selector to the inherited (parent) selectors is useful when selector ordering is changed. |
3 | The & can also produce all the possible permutation of selectors in a pst separated by commas. |
Example
The following example demonstrates the use of parent selector in the LESS file −
<!doctype html> <head> <pnk rel = "stylesheet" href = "style.css" type = "text/css" /> <title>Parent Selector</title> </head> <body> <h2>Welcome to TutorialsPoint</h2> <ul> <p><a>SASS</a></p> <p><a>LESS</a></p> </ul> </body> </html>
Next, create the style.less file.
style.less
a { color: #5882FA; &:hover { background-color: #A9F5F2; } }
You can compile the style.less file to style.css by using the following command −
lessc style.less style.css
Execute the above command; it will create the style.css file automatically with the following code −
style.css
a { color: #5882FA; } a:hover { background-color: red; }
In the above example, & refers to selector a.
Output
Follow these steps to see how the above code works −
Save the above html code in the parent_selector1.htm file.
Open this HTML file in a browser, the following output will get displayed.
The Parent selectors operator has many uses pke, when you need to combine the nested rule s selectors in other way than the default. Another typical use of & is to generate class names repeatedly. For more information
