# Copying CSS and HTML
### Copying child elements' CSS:
With CSS Pro, you can copy the CSS of the selected element and all its child elements. This can be turned on and off anytime at More > Settings > Child elements' CSS:
### Copying pseudo-classes pseudo-elements and media queries styles:
CSS Pro automatically copies all pseudo-classes such as `:hover`, `:active`, `:focus`, etc, and pseudo-elements such as: `:before`, `:after`, etc, **along with all media queries** automatically.
### Copying CSS variables:
CSS Pro automatically copies all CSS variables.
### HTML Code:
It's also possible to copy HTML code along with the CSS:
### Copying preferences for CSS selectors
**Copy original selectors**: CSS Pro will try its best to copy the selectors in their original form (removing invalid parts of it when necessary).
**Smartly generate selectors**: CSS Pro will generate a unique selector for every CSS. This generates a bigger output, but it's specific and won't cause conflict with your current CSS.
### Other copying preferences:
* **Convert font-size measurement units to px**
* If the CSS property `font-size` is declared on the element, will always be rendered in pixels.
* **Ignore box-sizing**
* Ignores the CSS property `box-sizing` (don't show it when inspecting elements, even if it's declared)
* **Ignore browser vendor prefixes**
* Ignores browser vendor prefixes such as (`-webkit-`, `-moz-`, `-ms-`, etc) (don't show it when inspecting elements, even if it's declared)
* **Ignore inherited properties**
* Ignores inherited CSS properties (such as `font-family`, `font-size`, `color`, etc)
* **Convert relative URLs to absolute**
* Converts all relative URLs to absolute in the CSS.
* Example: "`background: url(../assets/img.jpg)`" turns into "`background: url(https://yourwebsite.com/assets/img.jpg)`"
* **Nest pseudo-classes, pseudo-elements, and media queries (for SASS/LESS)**
* If you use CSS pre-processors like *SASS* and *LESS*, this can copy the code with the pseudo-classes, pseudo-elements, and media queries as "nested".
* **Don't copy CSS selectors when possible**
* If the copied code is simple (without child elements and without HTML code), it won't copy the CSS selectors.
* **Copy fonts**
* Copies the website's custom fonts imports (`@font-face` declarations with their URLs)
