So called userstyles can be used to change the look and feel of websites locally. Basic examples are to change the text color or size, the background color or the position of elements on a website. Most modern browsers come with capabilities to add styles directly or in the form of little files that include all the instructions.
One of the most popular destinations for custom userstyles is the userstyles.org web directory that lists thousands of styles for all sorts of purposes. When you visit the site you will notice that it recommends Firefox and the Stylish extension. There are however options available to install a style in Google Chrome or Opera. While Google Chrome users can install Stylish for their browser too, Opera users do not have that option.
It may be confusing at first to install styles in Opera, but once you know how it is done, it is not really complicated at all. Let me walk you through the installation of a custom user style.
To uninstall styles, simply delete them from the directory or move them out of it. Reloading is necessary here as well to complete the uninstallation.
There is another option, which can be useful if you only have a .css file for a specific site. You can assign custom CSS files to individual sites the following way:
Reload the page you are on to see the effects. To uninstall, simply remove the file from the same dialog again.
Update: As someone has pointed out, there is also an extension now available for Opera called Stylish which you can use for that purpose. It makes things a lot easier for Opea users as you can now install styles in the browser with a click.Advertisement
