Gantry Framework
Next Generation Template / Theme Framework
Develop CMS themes quickly and efficiently while providing flexibility and ease of use for end-users. Gantry was born when the RocketTheme development team wanted to consolidate our extensive set of custom Grav, Joomla and WordPress theme functionality into a simple, easy-to-use framework. Yes, that’s right! Gantry 5 has a powerful and easy-to-use Layout Manager that ensures controlling the layout is a highly visual experience. When we started the Gantry 5 project, we wanted to think past the concept of Gantry as a framework. We wanted to create something so versatile and powerful, that it could stand on its own as a platform, virtually independent of a CMS in concept and implementation. Utilizing a dual MIT & GPL license, Gantry is free to use pretty much anywhere! Designed from the ground-up with performance and efficiency in mind. Configure and structure your menu hierarchy with our new Menu editor. -

Minify
Go minifiers for web formats
Minify is a minifier package written in Go. It provides HTML5, CSS3, JS, JSON, SVG and XML minifiers and an interface to implement any other minifier. Minification is the process of removing bytes from a file (such as whitespace) without changing its output and therefore shrinking its size and speeding up transmission over the internet and possibly parsing. The implemented minifiers are designed for high performance. The core functionality associates mime-types with minification functions, allowing embedded resources (like CSS or JS within HTML files) to be minified as well. Users can add new implementations that are triggered based on a mime-type (or pattern) or redirect to an external command (like ClosureCompiler, UglifyCSS,). Minifiers or bindings to minifiers exist in almost all programming languages. Some implementations are merely using several regular expressions to trim whitespace and comments. -

Open Source Web Design Software Guide
Open source web design software is a type of software available to users for free, that can be used without restriction or cost. It relies on open source code which is available to everyone who has access to a computer and the Internet. Open source web design software allows anyone with basic programming skills to create, customize, modify and share their own websites. The most popular open source web design software is WordPress, Joomla and Drupal.
WordPress is an extremely popular content management system (CMS). It has thousands of plugins and themes for users to choose from, as well as built-in support for hosting your website on their servers. WordPress also offers its users easy navigation tools making it great for beginners. Additionally, WordPress has a huge community of developers actively contributing new features and fixes throughout the year.
Joomla is another popular open source CMS that allows its users full control over the development process thanks to its flexible templating system. Unlike WordPress’ more limited customization options when using themes, Joomla can be completely customized using either HTML or CSS coding languages allowing you near infinite possibilities when designing your site’s look and feel. Additionally, due to its vast array of extensions you can extend Joomla’s functionality almost infinitely depending on what you need it for—making it great for larger businesses looking for an advanced yet still manageable solution for their website needs.
Lastly there’s Drupal which was designed with versatility in mind from the beginning –so much so that even NASA uses it in developing their sites. Built specifically with high-traffic sites in mind Drupal makes sure your site scales up just as quickly as traffic does by utilizing caching modules and other techniques such as security audits—allowing even large companies total peace of mind when entrusting their websites into Drupal platform’s hands. Additionally Drupal comes packed with dozens upon dozens of modules expanding some core functionality out-of-the box making sure no matter what kind of website project you have planned; Drupal has got you covered whatever it may be.
All three CMS platforms mentioned above are incredibly powerful pieces of open source web design software allowing anyone regardless if they know how to code or not customize all parts necessary in order build any kind website they desire—for absolutely free.
Features Provided by Open Source Web Design Software
- Responsive Design: Open source web design software allows users to create responsive sites that look good and function properly on any device or screen size. This is important considering the growth of mobile and tablet usage, allowing developers to create sites that are flexible and accessible to a wide range of audiences.
- CMS Capabilities: Most open source web design software has content management system (CMS) capabilities built in, enabling users to easily manage their website’s content without having to write code from scratch. This includes features like media library integration for adding images and video, blogging tools, page templates for quickly creating pages, and built-in search engine optimization tools for optimizing content for better visibility.
- eCommerce Tools: Many open source web design software packages include ecommerce capabilities so customers can purchase products or services directly from your website. These tools often include payment processing, shopping cart systems, product catalogs, inventory management, shipping options, discount codes and more.
- User Management: Open source web design software provides user management functions so you can control who has access to your site's backend administration area as well as other areas of your site such as forums or members-only sections. This feature is useful if you have multiple people contributing content and need an efficient way to manage permissions/privileges for each user group.
- Modular Design Options: With modular design options included in many open source web design packages, it's easy to customize a website by dragging-and-dropping elements into place in the WYSIWYG editor without having to dive into code view or mess around with CSS settings. This feature makes it quicky and easy for newbies who are unfamiliar with coding languages yet need professional looking results fast.
Types of Open Source Web Design Software
- Content Management Systems (CMS): This type of web design software enables users to easily create, manage, and update content on their websites without having to write complex code. It is designed to be user-friendly and intuitive. CMSs come in a wide range of different styles and options tailored for individual needs.
- Code Editors: These are programs that allow users to manually write or edit raw HTML or CSS code to create a website from scratch. Professional developers often use these tools for customizing websites or creating unique designs. They can also be used by beginners with basic computer skills once they gain some familiarity with the underlying coding languages.
- Drag & Drop Builders: This type of software simplifies the process of website creation even further by allowing users to build pages using drag & drop modules instead of coding them from scratch. It is helpful for those who want more flexibility than what’s offered in pre-built templates but don’t want the complexity associated with writing code themselves.
- Template Engines: Templates provide a quick way to get started on a project without having to completely reinvent the wheel each time a page is created. They enable designers and developers to customize website layouts quickly while still providing an attractive look and feel. Many open source template engines have been developed which offer hundreds of free professional designs that are highly customizable according to individual requirements.
- Graphical User Interfaces (GUIs): Designed for non-technical users, GUIs provide visual representations of data and make it easier for people with less technical knowledge or experience interacting with web based applications such as blogs and forums, ecommerce sites etc. With GUIs, it’s possible for anyone – even those without programming background – to create sophisticated websites without understanding HTML, CSS or other coding languages required when using code editors or drag & drop builders mentioned above.
Advantages of Using Open Source Web Design Software
- Ease of Use: Open source web design software is user friendly, with intuitive and simple interfaces. This makes it easy to learn for users without any programming knowledge.
- Cost Savings: Using open source web design software eliminates the need for expensive commercial software licenses or subscriptions. This can translate into huge cost savings for businesses or individuals who are looking to develop their own websites.
- Flexibility: Unlike closed-source software, open source web design software allows users to modify and customize the code as needed, giving them greater control over the look and feel of their website. This flexibility also enables developers to make changes quickly without having to wait for vendor approval or support.
- Security: Open source web design software generally has more robust security than proprietary alternatives, due to the increased transparency that comes with an open source license. Developers can access the source code at any time, making it easier to identify potential vulnerabilities and fix them before they affect your website’s performance or security.
- Community Support: With an active community of developers contributing new ideas and fixes constantly, open source projects often benefit from a wealth of resources available online—including forums, tutorials, user guides, etc.—allowing you to get help when you need it most.

How Much Does Open Source Web Design Software Cost?
Open source web design software is available for free. There are many open source solutions available, such as WordPress, Drupal, Joomla., and Magento, which offer simple drag-and-drop web building interfaces with a variety of web design tools. You don't have to pay any licensing fees or purchase subscriptions to use these programs; they are completely free to download and use. Additionally, some providers also offer community support and access to a marketplace filled with themes and plugins that can help you quickly customize the look and features of your website.
Apart from the initial cost of Web hosting - typically within the range of $10-$15/month - there will be the cost associated with purchasing any premium themes and plugins that you choose to integrate into your website’s designs. These prices vary depending on the type of plugin or theme you buy, but typically range between $30-$200 per item. However, since open source software is regularly updated by their developers and supporters at no extra charge, any costly upgrades necessary for security or compatibility issues should not be a concern for most users.
What Does Open Source Web Design Software Integrate With?
Open source web design software is designed to be integrated with a range of other types of software, including content management systems (CMSs), e-commerce platforms, and analytics tools. CMSs can be used to manage the content of a website such as text, audio, video and images in an organized way. This can help create a more dynamic website with easy navigation for visitors. E-commerce platforms enable users to set up an online store and provide secure payment methods for customers who wish to buy products or services from their site. Analytics tools provide detailed data about how the website is performing in terms of the number of visitors it attracts and what pages they view on the site - this data can then be used to improve the effectiveness of marketing campaigns or change aspects of the website’s design in order to increase conversions. Finally, open source web design software can also integrate with plugins that extend its capabilities such as providing support for different languages or adding extra features like search bars or contact forms.

- Increased Security: Open source web design software is generally more secure than proprietary solutions, as it is subject to continuous review by a large community of users. This means that any security issues can be quickly identified and fixed.
- Easier Collaboration: By using open source web design software, developers can easily collaborate and share their work with others. This makes it easier for teams to work together on projects without having to worry about licensing restrictions or compatibility issues.
Getting Started With Open Source Web Design Software
- Getting started with open source web design software is relatively straightforward and often requires minimal setup. Firstly, the user must find an appropriate piece of software to download onto their computer. Websites such as GitHub or SourceForge are great places to start looking for popular open source solutions. On these websites, users can look for solutions that match their individual needs and read comments from other people who have used the software before.
- Once a suitable piece of software has been selected, it’s time to download and install it onto the user’s device. Most modern operating systems come with installation wizards which make this process very easy. However, in some cases additional manual configuration may be required once the installer is complete so be sure to read all instructions carefully.
- Now that the software is installed, users need to familiarize themselves with its basic features and functions as well as any specific language or syntax it uses (HTML/CSS/JavaScript etc). The best way to do this is by reading tutorials online or watching video guides on YouTube which will help you get comfortable with how everything works. There are also tons of available online documentation which explains how different functions work in detail if more information is needed.
- If users want a deeper understanding of what’s going on under-the-hood they should consider reading up on relevant programming language(s) so they know exactly what code does when writing HTML/CSS/JavaScript etc. It’s also possible for users to customize their experience even further by tweaking settings within the application itself; this allows them greater control over its behavior and appearance according to personal preference.
- Overall, getting started with open source web design tools can be rewarding but does require patience and dedication during initial setup and learning stages - but thankfully there are plenty of resources out there which makes things easier along the way.
