What should be done if the tick is not visible? - briefly
Verify that tick marks are enabled in the relevant settings and adjust the scale or display options to make them appear; if necessary, refresh the view or restart the application to force a redraw. Ensure that any visual filters or themes are not concealing the marks.
What should be done if the tick is not visible? - in detail
When a check‑mark element fails to appear on a page, the first step is to confirm that the element exists in the document structure. Open the developer tools, locate the element by its identifier or class, and verify that it is present in the DOM tree. If the node is absent, the rendering code responsible for creating the element must be examined for conditional logic that may prevent insertion.
Next, assess the styling applied to the element. Check for properties that could hide it, such as display: none, visibility: hidden, opacity: 0, or positioning that moves it off‑screen. Ensure that any media queries or theme overrides do not inadvertently conceal the symbol. Correct or remove conflicting rules to restore visibility.
If the element is present and styled correctly, investigate script execution. Confirm that JavaScript responsible for toggling the tick runs without errors. Look for console messages, unhandled exceptions, or asynchronous calls that may be blocked. Repair faulty logic or add fallback code to guarantee the element’s activation.
Browser rendering issues may also affect visibility. Test the page in multiple browsers and devices to rule out vendor‑specific bugs. Clear caches, disable extensions, and verify that font files containing the tick glyph are loaded without errors.
For automated testing, incorporate explicit checks that assert the element’s visibility state. Use assertions that fail when the element’s offsetWidth or offsetHeight is zero, or when computed styles indicate hidden status. Provide descriptive error messages to facilitate rapid diagnosis.
If all corrective actions are ineffective, implement an alternative representation. Replace the missing graphic with a Unicode character (e.g., ✓) or an SVG icon that does not rely on external assets. Ensure the fallback is styled consistently with the surrounding interface.
Summarized actions:
- Verify element presence in the DOM.
- Inspect CSS for hiding properties or conflicting rules.
- Debug JavaScript that controls visibility.
- Test across browsers and clear caches.
- Add automated visibility assertions.
- Provide a reliable fallback icon.
