Use × as close button instead of letter X

[Serhii-DV]

Hi.

Please, just see this image example:

I make font-size: 22px

Besides, × is used in Twitter Bootstrap.

+1 – I like it!

Would also replace the font weight from normal to bold to emphasize this close button a little bit more:

font-weight: bold;

I like the Heavy Multiplication x

using

& #10006;

×

Or better use the smaller one:
