If you're comfortable working with HTML, Sandvox gives you the freedom to focus on custom markup while letting Sandvox manage the HTML that makes up the foundation of each page or collection. Edit HTML or JavaScript in the HTML editor window with syntax coloring and you'll see the changes instantly applied to the page.
As long as your website host supports PHP or other scripting languages, you can easily enter these as well. To review the results of adding these scripts just upload the website and view it from the host's server.
Raw HTML Pages and Objects: Need custom code on your site? Sandvox makes it easy to insert a block of Raw HTML without modifying any of the structural elements of the page. Or, choose a Raw HTML page and create a completely customized page within your overall website.
Code Injection: Sandvox's Code Injection panel makes boosting your website with custom HTML, JavaScript, or scripting code - such as PHP - simple. Insert custom code in specific places outside of the <body> text to further customize and enhance your site's capabilities.
HTML Validation: Incorrect HTML can cause your site to offer substandard performance or look different to your visitors. With Sandvox, HTML validation is simple because it's integrated directly with the W3C Validator.
