Sass vs GIMP

You are able to declare custom functions with Sass (for example, converting units) which can be easily invoked, even when using shorthand properties. This results in cleaner, more reusable code.

Sass allows you to nest selectors which results in code that is both faster to write and cleaner to read.

For example, this:

.parent 
  color: blue
  .child
    color: yellow

Will compile to this:

.parent {
  color: blue;
}
.parent .child {
  color: yellow;
}

Another big advantage for Sass is the very active community pushing the development forward at a rapid pace. Sass is constantly coming out with bug fixes, and are often the first to come out with improvements.

This is an important factor to keep in mind when picking a preprocessor to invest your time into.

It comes with two possible syntaxes:

• Sass - No parens or semicolons allowed and the nesting is dictated with whitespace.
• SCSS - SCSS syntax is a superset of CSS – which means SCSS can be written as CSS, but has been expanded to include the features of Sass as well.

SCSS is easier to pick up for beginners and Sass has a cleaner syntax. Having both syntaxes means you can pick the one that best suits your coding style.

The mandatory syntax rules for both SCSS and Sass results in a more consistent code. For a more detailed analysis between Sass and SCSS go here. To see a nice comparison of the Sass syntax against CSS and SCSS go here.

Sass simplifies minifying CSS files by offering a one-line command that will output a minified version.

It's very comfortable and easy to write/learn Sass, even for beginners.

Sass can be used with a framework called Compass, which provides additional functions and mixins which can reduce the amount of code you have to write.
For example, Compass will take care of vendor prefixes.

This:

div {
    background-image: -webkit-linear-gradient(#F00, #000);
    background-image: -moz-linear-gradient(#F00, #000);
    background-image: -o-linear-gradient(#F00, #000);
    background-image: linear-gradient(#F00, #000);
   }

Can be written as:

.gradient {
    @include background-image(linear-gradient(#F00, #000));
}

For a full list of features, check out the Compass documentation.

Rather than being limited to editing the outputted CSS file in devtools, with source maps you are able to manipulate the original .scss file.

There is also a C/C++ port of the Sass CSS precompiler called Libsass that decouples Sass from Ruby. It is very fast, portable and easy to build and integrate with a variety of platforms and languages.

The latest implementation of Sass is written in Dart, and compiles to pure JS with no native code or external dependencies, means you no longer need Ruby or libSass.

Since it's written in Ruby, it's easier and faster to use with Ruby apps.

GIMP is completely free and open source, meaning you can use GIMP and all of its features without spending a penny. This makes it an excellent case for artists or designers who may not have the budget to spend over 700 USD on Photoshop. It is also available for free on Windows, Mac OS and Linux. It's licensed under GPL with source code available here.

GIMP is the most feature rich free image editing tool. It has most image manipulation and workflow tools that you would expect from an image editing software and what it lacks it makes up with plugins.

There's a content-aware fill plugin available for GIMP.

By default GIMP splits out each window, but you can check to use the one screen mode in options if you prefer.

Compared to to other photo editing software, GIMP is very light weight. In addition it isn't very resource-intensive, meaning you can put it on a flash drive and have it with you to load up on just about any computer.

Gimp has less features than programs like Photoshop, but for a beginner, or someone not needing complicated options, Gimp is the perfect choice. It allows you to quickly do basic photo manipulation so you can easily get the product you need without having to worry about complicated features getting in the way.
