Hi everybody. I get two errors from the links on the map:

a: 'Report a problem' Violation 339 CCR of 3.6, adjust foreground and background colors to exceed 4.5. a: 'OpenStreetMap' Violation 341 CCR of 3.6, adjust foreground and background colors to exceed 4.5.

Could you please help me to fix them? It seems that the contrast is not respected. Thanks. Monica.

Which map (app, website, ...) are you talking about and what are you trying to do when the error appears?

I have an iframe with the OpenStreetMap on my website, and the two links on it (report a problem and OpenStreetMap) don't respect contrast color analysis. Is there a way to change their color? Thanks.

Not with the one you are using. You would have to find a different tile source w/ higher contrast, e.g. set up your own style with a vector tile provider or set up tiles yourself.

You say "I have an iframe with the OpenStreetMap on my website". What do you mean by "the OpenStreetMap"? I can't see exactly the text that you are referring to at https://www.openstreetmap.org .

Look at the map at the end of this page, please: http://pa6.produzione.clio.it/ I don't know how to set up my own style. Can you help me? Thanks. Monica.

That's a Google map (for me, at least). The terms link is to https://www.google.com/intl/en-GB_US/help/terms_maps/ .

That embed link is https://www.openstreetmap.org/export/embed.html?bbox=17.732620239257816%2C40.18097176388722%2C18.443984985351566%2C40.5268484330944&layer=mapnik . The source is visible (at least in Firefox) as view-source:https://www.openstreetmap.org/export/embed.html?bbox=17.732620239257816%2C40.18097176388722%2C18.443984985351566%2C40.5268484330944&layer=mapnik">https://www.openstreetmap.org/export/embed.html?bbox=17.732620239257816%2C40.18097176388722%2C18.443984985351566%2C40.5268484330944&layer=mapnik">view-source:https://www.openstreetmap.org/export/embed.html?bbox=17.732620239257816%2C40.18097176388722%2C18.443984985351566%2C40.5268484330944&layer=mapnik . There are two links in there - the css and the javascript. To modify that embed link you'd need to take a copy of those three things and edit them so that they do what you want to do (it's the javascript that handles the "report" button).

Perhaps easier would be to use Leaflet (the Javascript library that OpenStreetMap.org uses) yourself to embed a map - see https://leafletjs.com/.
