The indentation for the file is not consistent, please use 2 spaces and don't create an empty new line just after opening a new tag or just before closing a tag. Also please use the xhtml syntax for self-closing tag (<br /> instead of <br>).
Make sure all the content is in a <main> tag and each section in a separate <section> tag.
<div> <div> <span>Text</span> <br> </div> </div>
<div> <div> <span>Text</span> <br /> </div> </div>
Indentation is broken and a coma is missing at the end.
Please remove this button and the css code for it. If we want to add such a button it should be for the complete website.
Don't use <br> and instead give the items an block display.
Can you explain the process of choosing which frameworks to highlight?
Why are we listing flatpack as the first deployment option and distros last? Is the order random or do you want to show a preference here?
Caps feel weird here.
Did you count all frameworks? Also this number is not static and subject to changes
I would move this in the top row as it documentation of developing for one of our products and the inqlude one down next to Qt.
For frameworks, 3 of them were suggested by Carson Black. And the other were mentioned in a couple of places outside api.kde.org . I guess you can consider that the choosing was random
for packaging, It was random. Pls suggest the preference order so that I can make the necessary changes
I would probably drop the question at the beginning of this paragraph, and rewrite this sentence to sound more confident instead of using "can use."
I would drop "the best thing" and "i.e." as they don't make the sentence sound very professional.
This section has some style problems:
I would probably drop "KDE" from here
Like above, drop the question and rewrite. You probably don't need this sentence in the first place anyways.
Like above, don't duplicate the name of the tools when describing them
Not sure I would have the HIG be just a "pro tip"
Again, inconsistent period usage and duplication of format name
Distro packaging probably shouldn't link to the appimage github.
Duplication of tool name
I would drop "KDE isn't the only community developing with Qt," "not just those by the KDE community," and drop duplication of tool name.
