Robert, i have one of these aluminum floor jacks,

it fits under the front of my Miata without any problem. If you are looking for smaller and lighter this one would work,

But if your car has been lowered you might have a problem, my little brothers Miata has been lowered about an inch and has a slightly larger front air dam than mine and he has to drive up on a couple of two by tens laid flat on the ground if i want to jack the the front end off of the ground. And that is only to clear the air dam. I don't think that you would have a problem with a Civic just jacking up one tire even if it had a flat. The handles on these also break down into two pieces, so you can store it easier.

Whatever jack you decide to use be sure you test it, a friend of mine had his brand new floor jack break when he lifted the front of his car. This also reenforces the idea of using jack stands before crawling under your vehicle.
