WHAT IS THIS PAGE FOR?
A quick support guide for using Teletext Tools safely on phones, tablets, laptops and desktop screens.
BEST STARTING CHECKS
Use a modern browser, keep zoom moderate, and switch orientation if a very small screen feels tight.
WHAT THIS GUIDE COVERS
Devices, browsers, touch, keyboard input, text size, colour, screen readers, reduced motion and reporting layout faults.
iPHONE
Supported. Phone layouts use compact rows and internal screens to avoid hidden footer content.
iPAD
Supported in portrait and landscape. Wider screens may show more text with safer spacing.
ANDROID
Supported in modern Android browsers. Chrome is usually the most predictable comparison browser.
WINDOWS / MAC
Supported on modern desktop browsers. Keep browser zoom close to 100% for the cleanest fixed frame.
SAFARI
Supported on iOS, iPadOS and macOS. iOS may need brief tap protection after swipes.
CHROME / EDGE
Supported and usually consistent on desktop, Android and modern tablets.
FIREFOX
Supported. If a tool behaves oddly, test Chrome or Edge to compare browser behaviour.
PRIVACY BROWSERS
Most pages work, but strict storage blocking can stop remembered settings from saving.
SWIPE USE
Swipe left or right to move between internal screens such as 1/11 and 2/11.
PAGE NUMBERS
Swiping changes only the internal guide screen. It does not jump to a different Teletext page number.
GHOST TAP SAFETY
After a swipe, taps are briefly blocked to prevent accidental link jumps on touch devices.
BEST USE
Swipe, pause briefly, then tap. This makes iPhone and iPad navigation more predictable.
PAGE BOX
Enter three digits for Teletext page jumps. Example: 101, 107 or 199.
DECIMALS
For calculators, use a dot for decimals, such as 1.5. Some mobile keyboards show commas.
MOBILE KEYBOARD
If the keyboard covers the bottom row, tap outside the input to reveal the full frame again.
KEYBOARD USERS
Use normal tab focus, links and buttons. Tool-specific shortcuts should stay simple and visible.
WHY TEXT CAN CLIP
Teletext Tools uses a fixed TV-style frame. Extreme zoom can push text beyond safe rows.
DESKTOP ZOOM
Keep browser zoom near 100% for best fit. Reload after changing zoom.
MOBILE TEXT SIZE
Moderate OS text size works best. Very large display zoom may reduce available row space.
SAFE DESIGN RULE
Pages should split into more internal screens instead of forcing hidden vertical scrolling.
WHY THESE COLOURS?
The Teletext palette is bold, familiar and designed to separate labels, links and warnings quickly.
COMMON MEANINGS
Yellow marks emphasis. Cyan marks structure. Red marks warnings.
PHOTO BACKGROUNDS
Clock and display pages work best with darker, simpler images behind text.
READABILITY
Do not rely on colour alone. Important controls should also have clear labels.
STRUCTURE
Pages use headings, sections, links and buttons where possible while preserving the Teletext look.
FAST NAVIGATION
Use links lists, landmarks and the Index page at 199 to reduce scanning.
PAGE BOX
The page box is part of the locked frame and should remain discoverable across pages.
DENSITY NOTE
Teletext is intentionally compact, so longer help text is split into internal screens.
FLASHING
Teletext Tools aims to avoid flashing effects. Transitions should be short and functional.
REDUCED MOTION
If reduced motion is enabled, internal screen movement is removed by CSS where supported.
WHY ANY MOTION?
Short transitions act like page turns, helping users understand where they moved.
SAFE USE
Use PREVIOUS and NEXT buttons instead of swiping if motion or touch input feels uncomfortable.
COMMON SEARCHES
Teletext Tools accessibility, iPhone support, browser support, screen reader support, zoom clipping.
WHO USES IT?
Phone users, tablet users, keyboard users, screen reader users, testers and people reporting layout issues.
COMMON USE CASES
Checking if a tool works on mobile, fixing hidden text, checking browser behaviour and reporting overlap.
TAPS NOT RESPONDING?
If you just swiped, pause briefly and tap again. Then try one reload.
SETTINGS NOT SAVING?
Private browsing or strict privacy tools may block local storage. Try normal mode.
TEXT OVERLAPS?
Overlap with the header or footer is a layout fault. It should be reported, not ignored.
REPORT DETAILS
Include page number, device, orientation, browser and what was hidden or overlapping.
