Escaping Colons in CSS Selectors for Namespaced Elements

When using JavaScript frameworks like JSF, it's common for input field IDs to contain colons, which can interfere with CSS selector specificity due to their resemblance to pseudo-element syntax. To handle this, a simple solution is to escape the colon using a backslash.

input#search_form\:expression {
  // CSS styling here...
}

This syntax informs the browser that the colon is part of the element ID itself, rather than initiating a pseudo-element selector.
