Recently, I stumbled upon this code snippet in our codebase:
li.ng-binding span {
font-size: 13px;
font-family: Arial, Helvetica, sans-serif;
font-weight: bold;
}
The selector above doesn't actually apply to one of the intended 'li' elements due to the presence of .ng-binding within it. Even though this code functions as expected, should including ng-binding in a CSS selector be considered a best practice?
Your reservations are valid. The primary purpose of CSS is to separate the content of a document from its presentation (structural separation). Angular serves as an intermediary for binding attributes to HTML DOM elements, making it necessary to use standard or custom directives like ngStyle to style DOM elements effectively.
Additionally, upon further investigation, there is a "ng-binding" class used internally by Angular. By inspecting the source code for ngBind, we can see that it adds this class and links the binding with .data:
In Angular versions before 1.3, there is a reference to this:
element.addClass('ng-binding').data('$binding', attr.ngBindHtml);
I do not recommend utilizing this class.
