Buttons navigation menu with CSS Sprites

dito_cattelan2

In today's tutorial we talk again about HTML graphics and CSS integration. In my article a few months ago I talked about the technical (also widely used by Google) of CSS sprites. In practice consists in inserting the majority of images repeated several times within the page into one big image, that will be called multiple times with our CSS.

As a matter of personal preference I tend to avoid using Gimp every time I have to create a different menu item navigation, I prefer to create only the backgrounds of buttons and then think about the styles using CSS. In this way, the first menu is better indexed by search engines, secondly I avoid "waste" the time to create me to every button a new image.

Change the dpi / ppi of an image with Gimp

schema_dpi

I often find myself having to create images that serve as separator content within prints, or some simple graphic effects created with tracked, or with letters. I'm thinking of something very simple, that surely even in the old schoolbooks we were used to seeing without realizing.

Occasionally, however,, I happen to create the new image, save, and realize that the work is finished the dpi is too low Gimp because those who apply by default are 72, excellent to the web but too little for a detailed Print quality. Today we see how increase the dpi of an image we have already saved with Gimp 72 dpi, and the portarla 300 (great for Print).
