Review Summary

Changes are needed because the current click-to-container coordinate calculation fails when the wall element itself is scrolled, so the spider is not positioned under the cursor in that case. In src/scripts/main.js, inside the container click handler where you compute clickX and clickY from event.clientX/event.clientY and container.getBoundingClientRect(), you're currently ignoring the container's internal scroll offsets. This breaks the requirement that the spider's center must land exactly under the pointer and stay within the wall boundaries for all wall states, including when the wall content is scrolled.

To fix it, adjust your coordinate math to add container.scrollLeft and container.scrollTop (while still subtracting container.clientLeft/container.clientTop), for example:

const clickX = e.clientX - rect.left - container.clientLeft + container.scrollLeft;
const clickY = e.clientY - rect.top - container.clientTop + container.scrollTop;

so that the computed position is relative to the scrolled content, not just the visible portion. Once you correct these coordinates, your existing centering and clamping logic based on the spider's size and the wall's client dimensions should correctly keep the spider within bounds again. As a minor, optional robustness improvement, you might also consider using rect.width/rect.height consistently when comparing against viewport-based positions, but this is not required for acceptance. Aside from the scroll-offset issue, the rest of your solution (centering under the cursor, proper clamping, no hardcoded sizes, and correct use of clientX/clientY) looks solid, so addressing this bug should be enough to fully satisfy the task requirements.

The click-to-container coordinate calculation doesn't include the container's scroll offsets. If the wall element is scrolled, you need to add container.scrollLeft / container.scrollTop to the computed values so the spider is positioned relative to the content (e.g. const clickX = e.clientX - rect.left - container.clientLeft + container.scrollLeft; and similarly for Y).

Review Summary

Your solution is approved because it correctly implements all the required behavior for moving the spider. On click, the spider moves so that its center is positioned under the cursor, using event.clientX/event.clientY along with the container’s bounding rect and scroll offsets, which also fixes the prior scrolling bug. You clamp the computed x and y values so the spider cannot move outside the wall, and you avoid hardcoded sizes by relying on spider.offsetWidth and spider.offsetHeight, which matches the task requirements. It’s also good that you kept the changes focused only in src/scripts/main.js, respecting the constraint to limit modifications to that file. As a minor improvement (not required for this task), you could review the part of the click handler where you compute maxX and maxY using container.clientWidth/clientHeight and consider whether scrollWidth/scrollHeight would better match cases where the wall content is larger than the visible area. Overall, this is a clean, focused implementation that meets the functional criteria—nicely done.
