CSS Columns

column-count

Below is an example of CSS columns. This uses column-count, as:

#col1 { -moz-column-count: 2; -webkit-column-count: 2; column-count: 2; }

One of the more difficult things for beginners is understanding what the meter is telling you. This is largely due to the actual readout, which varies greatly from one camera to another, and one manufacturer to another. Again, best to go to the manual. In general, the meter will read the scene, then tell you whether you are over- or underexposing the scene, using the current shutter speed and aperture settings. You then adjust these setting, either or both, to get to the correct exposure.

Probably the simplest meter to read was/is the Pentax K1000. It uses a needle, which moved up and down. There was a kind of slotted opening. When you are at the correct exposure, the needle would be centered in this opening. Both Canon and Nikon use an LED readout in their professional cameras, with a center point, and then bars representing stops, subdivided into thirds of stops. Fairly straightforward. There is a plethora of other schemes used to display exposure information.

column-width

Another way of doing it is to use column-width, as:

#col2 { -moz-column-width: 15em; -webkit-column-width: 15em; column-width: 15em; }

While column-width works fine, the width must but set explicitly, not by percentage (at this point). The browser will make as many columns as it can with that set width.
