An article grid is usually designed as a finished picture: every thumbnail has arrived, every title fits and all the cards sit neatly in place. Visitors encounter a process instead. Text and images arrive at different times, and an occasional image never arrives at all.
I judge the grid throughout that process. A layout that becomes orderly only after several seconds can still make the page difficult to use, especially if a link moves just as somebody tries to select it.
Decide whether uneven columns are useful
A masonry arrangement can suit a visual collection, but it is not automatically the best answer for news or advice. I ask whether the varied card heights help people browse or simply introduce another moving part. A regular grid often makes the reading order and comparison between items easier to follow.
The content should lead that decision. A collection of differently proportioned artwork has different needs from a list of articles with a title, date and short summary. Choosing a layout because it looks interesting in a demo can leave editors compensating for it later.
Before adding script-driven positioning, I try the simplest layout that expresses the intended order. If the design does need extra behaviour, its failure mode belongs in the brief: what should a reader see while the script or images are unavailable?
Give the image a place to arrive
A thumbnail area should not have to invent its size after the rest of the card appears. I establish the intended image shape and check how the crop treats the subject. That gives the surrounding text a more predictable place to sit.
Uniform dimensions are not permission to crop carelessly. An image containing a person, product detail or embedded words needs inspection at the actual card size. Sometimes the correct editorial answer is a separate thumbnail, not a more elaborate layout rule.
I also decide what happens when no image exists. A plain card with a useful heading may be perfectly sensible. An empty broken-image box suggests a failure even when the article itself is available. The fallback should be intentional and should preserve access to the content.
Test the sequence rather than the screenshot
On a test copy, slow the connection and watch the first load. Check whether cards overlap, whether titles remain readable and whether the reading order changes unexpectedly. Then repeat with one missing image and with a very tall source image.
Where positioning depends on image completion, that dependency needs an explicit implementation and a recovery path. I do not assume a layout event will happen in the order it happened on my own fast connection. A repeat visit can behave differently because some resources are already cached.
Keyboard navigation is another useful check. The order in which links receive focus should remain understandable alongside the visible arrangement. A grid that looks sorted one way and moves through links another way deserves a closer review.
Give editors examples they can reuse
I keep a small sample set: a short title, a long title, a missing thumbnail and a normal article. Editors can use those examples to judge future changes without learning the layout code.
The acceptance question is simple: can somebody choose and open an article before everything finishes loading? Once that works dependably, visual refinements have a solid base. An attractive final arrangement is valuable, but it should not come at the cost of a confusing arrival.
