The translateX() and translateY() functions in CSS are used to move an element along the X and Y axes respectively. If they are not functioning properly, there could be a few reasons for this:
1. Incorrect syntax: Make sure that the syntax of the transform functions is correct. They should be written as "transform: translateX(value) translateY(value);" where "value" is the distance you want to move the element.
2. Parent container positioning: If the parent container of the element is not positioned properly (e.g. relative, absolute, fixed), the translate functions may not work as expected. Make sure the parent container has a position other than the default static.
3. Conflicting styles: Check for any other CSS styles that may be overriding or conflicting with the translate functions. This can include margins, padding, or other positioning properties.
To improve the CSS code for proper display of elements on the page, consider the following:
1. Use proper units: Make sure to specify units for the translate values (e.g. px, %, em) to ensure consistent positioning across different screen sizes.
2. Test in different browsers: Check the page in different browsers to ensure that the translate functions work as expected across various platforms.
3. Avoid unnecessary transforms: Limit the use of translate functions to only when necessary, as excessive transforms can impact performance and responsiveness.
4. Use a CSS preprocessor: Consider using a CSS preprocessor like Sass or Less to write cleaner and more efficient CSS code, which can help in organizing and optimizing transform functions.
