- Who is the HTTP Status Codes poster for?
- HTTP Status Codes belongs to the Computing section rather than to a school year, because computing is not something one grade owns. Anyone learning the web can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the HTTP Status Codes poster?
- The first digit tells you where to look: 4 means fix the request, 5 means fix the server. A wall chart earns its place by being glanceable from where the work is happening, so HTTP Status Codes belongs on the wall where that computing work actually happens, within glancing distance, rather than filed away.
- What other posters go with HTTP Status Codes?
- Accessibility, ARIA and How a Browser Renders sit alongside HTTP Status Codes in the Computing section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AccessibilityARIAHow a Browser Renders
- Is the HTTP Status Codes poster free to download and print?
- Yes. HTTP Status Codes downloads as a free PDF with no account, no email and no watermark, like everything else in the Computing section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the HTTP Status Codes poster print at?
- HTTP Status Codes is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of HTTP Status Codes loses nothing.Printing guide
