  1. font size adjustment is missing

    • Hi,

      Font size adjustment is currently not supported yet, but you can edit the file “/Applications/HelloWeb.app/Contents/Resources/Assets/UI/edit.html” and add one line of code before “__hw_editors[lang] = editor;”:

      editor.setOptions({fontSize: "15pt"});

      Please change "15pt" to the size you would like, and restart HelloWeb when you finish.

      Thank you!

  2. hi, thanks for the reply. unfortunately, I can’t succeed. first, when I try to edit the edit.html system doesn’t give permission and say I can edit If I duplicate the file. Then I duplicate it, delete original edit.html from the folder, add the line of code you gave as

    });
    editor.on(“change”, function() {
    document.location = “helloweb-internal://event/text-changed”;
    });
    editor.setOptions({fontSize: “24pt”});
    __hw_editors[lang] = editor;
    }
    __hw_editors[“html”].focus();

    then save it to desktop and copy to the application folder. quit restart the app, and every time I get a white screen on application’s window. How can I fix this problem? thanks.

  3. problem solved, thanks :smile:
