Left/Right Column Width Issue After Custom Style Updates – Panels Not Resizing to 180px
Posted: 7. December 2025 12:56
Hi everyone,
I’m running Board3 Portal on phpBB and recently updated parts of my custom style (CSS + header layout). Since then I experienced an issue where the left and right portal columns would not properly respect the configured width of 180px.
Symptoms I was seeing:
* Portal panels (left/right blocks) appeared wider than 180px even though the ACP setting was correct.
* Some Revive Adserver iframe ads would overflow or create a small horizontal scrollbar.
* Large empty grey areas appeared inside certain panels.
* Adjusting the column width in ACP had no visible effect.
What caused it:
After some investigation, it turned out the issue was due to custom CSS overrides in my style (styles/lsf/theme/lsf.css).
A section had been added that unintentionally targeted:
Because of these selectors, the portal columns stopped using the default widths defined by Board3 and ignored the ACP column-width settings.
Fix/Resolution:
* Removed the custom CSS rules that referenced #portal-left or #portal-right.
* Cleared phpBB cache + browser cache.
* Reset column widths in ACP → Extensions → Portal → Column width settings back to 180px.
After doing this, the portal layout returned to normal, and all blocks now correctly follow the 180px width again.
Posting here in case it helps others:
If anyone else finds their Board3 column widths “stuck” or behaving unpredictably, I recommend checking for style-level CSS overrides that may be affecting portal containers.
Thanks for maintaining this extension; it’s excellent once everything is playing nicely together.
Cheers,
Phil
