How to Specify User Agent with cURL

Over the years I've shared how to perform a number of actions with cURL: how to send POST data, how to retrieve headers, follow redirects, check GZIP encoding, and more. Another useful cURL directive is sending the user agent, as some servers respond with different content or headers depending on the user agent. Let's have a look at how easy it is to send the user agent with cURL!

The user agent may be sent with the -A or --user-agent directives:

curl -A "MY-USER-AGENT" https://www.whatismybrowser.com/detect/what-is-my-user-agent

# .... Your user agent is: `MY-USER-AGENT` ...

Luckily we don't rely on user agent strings as much as we did in the early days of the web, but we'd be naive to assume that they no longer modify the output of all websites!

    MooTools: Set Style Per Media

    I'd bet one of the most used MooTools methods is the setStyle() method, which allows you to set CSS style declarations for an element. One of the limitations of MooTools' setStyle() method is that it sets the specific style for all medias.
