When I experimented with scrolling, I found it hard not to lose understanding where I just scrolled from. What helped immensely was defining a top and bottom margin and using vim-smoothie.
This is very detailed introduction and documetation of a lense-based architecture in react. [2]
At the first glance it looks kind of overwhelming but it contains lots of examples.
This is a case study of many rather complex components. [3] The codinsteade is rather quick and dirty hacked together and at the first glance not really readable but thats kind of the point: even complex components can simply be composed locally from many small parts of requiring some global controller managing the state and keeping it consistent.
You have basically six cells. Five of them (lorem, ipsum, dolor, sit, amet) are 1x1, and the other one (foo) is 1x5.
What I do is, I draw the UI I imagine on a paper, add a grid where the smallest UI elements (labels, buttons, fields) their own, suitable $WIDTHx1 cells.
Some cells like "foo" needs to span mutliple cells (like this 1x5) to look and place correctly. At the end, you have a "spreadsheet like view" with some cells "merged and centered" in spreadsheet software parlance.
As the last step, I note the dimensions of the cells I need to realize the UI on the paper, and write the code reflecting that.
Not sure if this is standard for programming competitions, but I'm not a fan of this rule:
> During the qualification stage, the proctoring system must record the entire process of completing the problems. The recording must include video materials showing the participant, their computer screen, and the surrounding area.
> After completing the qualification stage, the participant must upload the recording to a convenient platform (for example, cloud storage or YouTube).
I've been using { and } more as well. Mostly to navigate paragraphs of prose, but sometimes for code too.
