Learn Basics of Linux

1. What is Linux? Linux is a free Unix-type operating system for computer devices. The operating system is what makes the hardware work together with the software. The OS is the interface that allows you to do the things you want with your computer. Linux is freely available to everyone. OS X and Windows are other widely used OS. Linux gives you a graphical interface that makes it easy to use your computer, yet it still allows those with know-how to change settings by adjusting 0 to 1 . It is only the kernel that is named Linux, the rest of the OS are GNU tools. A package with the kernel and the needed tools make up a Linux distribution . Mandrake , SUSE Linux , Gentoo and Redhat are some of the many variants. GNU/Linux OS can be used on a large number of boxes, including i386+ , Alpha, PowerPC and Sparc. 2.

Ten CSS tricks

1.  CSS  font shorthand rule When styling fonts with  CSS  you may be doing this: font-weight: bold; font-style: italic; font-variant: small-caps; font-size: 1em; line-height: 1.5em; font-family: verdana,sans-serif There's no need though as you can use this  CSS  shorthand property: font: bold italic small-caps 1em/1.5em verdana,sans-serif Much better! Just a few of  words of warning : This  CSS  shorthand version will only work if you're specifying both the  font-size  and the  font-family . The  font-family  command must always be at the very end of this shorthand command, and  font-size  must come directly before this. Also, if you don't specify the  font-weight ,  font-style , or  font-variant  then these values will automatically default to a value of  normal , so do bear this in mind too. 2. Two classes together Usually attributes are assigned just one class, but this doesn't mean that that's all you're allowed. In reality,  you can assign

How To tie a Tie

Image
A necktie (or tie) is a long piece of cloth worn for decorative purposes around the neck or shoulders, resting under the shirt collar and knotted at the throat. Variants include the ascot tie, bow tie, bolo tie, and the clip-on tie. The modern necktie, ascot, and bow tie are descended from the cravat. Neck ties are generally unsized, but may be available in a longer size. Men and boys wear neckties as part of regular office attire or formal wear. Neckties can also be worn as part of a uniform (e.g. military, school and waitstaff), whereas some choose to wear them as everyday clothing attire. Neckties are traditionally worn with the top shirt button fastened, and the tie knot resting comfortably between the collar points. However, it has become common in recent times for neckties to be worn as a casual item, tied loosely around the neck, nearly always with one or several buttons unfastened. Originally worn for warmth by soldiers, the tie appeared in France during the reign of Louis
