*Dual View & Google Search & Syntax Highlighter HTML Viewer!! *High quality but simple. Corresponding to search Google, it is a two-screen HTML Viewer. NEW!! Syntax Highlighter like "Sublime text" *Syntax Highlighter is heavy process. If loading time is too long, you had better changing background color to "Blue". (No Syntax Highlighter mode) [How to use] Browser screen left, the right to display the HTML source at the same time . Make it easy to adjust the width of each screen. You can check the HTML source to compare left and right. Because it corresponds also "Google search", you do not need to directly hit the URL. HTML source is also updated in real time when you open a new page. I also support shared from the browser. *Full Screen Mode: Double-tap on source view [Features] Unlike the HTML Viewer to display the hit URL, you can use "Google Search". Because every time you open a new web page, HTML source will be updated automatically, it is also useful to check the entire site. Simple, easy to use and safe operation as well, it is a handy HTML Viewer !! This app is best HTML Viewer !!

Inspect elements in Safari on iPhone and iPad. View HTML and CSS, read JavaScript console errors, review captured network requests, and explore page source and website assets in the Safari page you’re already using. Built for frontend developers debugging the mobile web. Safari inspection • Elements: select a node on the page, browse the DOM, inspect styles, and try local CSS edits. • Console: evaluate JavaScript and read captured logs, errors, and available stack information. • Network: inspect requests observed after capture starts, including available status, timing, and response details. • Source: read the source available to the extension and distinguish it from the live DOM. • Resources: explore scripts, stylesheets, images, and available page storage. Start capture before reproducing a problem. Safari permissions, browser boundaries, and capture timing can limit the evidence available. Codable does not provide every capability of desktop Web Inspector. Tools in the companion app • Resize: test responsive layouts with custom viewport dimensions, device presets, scale controls, and resize handles. • Scratchpad: write and run JavaScript with syntax coloring, code keyboard shortcuts, and document support. Optional Apple Intelligence assistance is available on supported devices. • Extension setup: enable Codable in Safari and practice with the bundled demo website. The Safari extension works in your current Safari page. Resize uses a separate browser session. Optional support Codable is free to use. The Tip Jar offers optional, repeatable one-time purchases through Apple. Tips unlock no features and are not subscriptions.
