Looks like you fixed it yourself... It would help if you would describe your issue.
I hear that a picture is worth a thousand words.
In this case, a picture is worth at least a few words (of explanation )
"Rear photo is my home page"....
Don't you mean that is your desktop background picture? Not really your home page.
It appears that you have changed the font size, or the zoom settings in your Chrome browser.
You can make that zoom setting smaller by holding Command, then press minus (-). Each time you press that key combo, the zoom setting will change (and everything in the Chrome window gets smaller). Press Command (+) to make the window contents larger, or click on View/Actual size, which resets the Chrome window to, well, actual size. You may also have changed settings in Chrome/Preferences, scroll to Appearance settings. Make sure that Zoom is set to 100%. This is NOT the same as the key combo Zoom setting. They can each be set differently, so double check the settings on both. You will see the setting number change when you do the key combo. Set to 100%, just to make sure it is at default, then recheck the page zoom setting in the Preferences, to make sure it is also still set at 100%.
NOW, make changes if you prefer some different page zoom, or maybe a different font size.
Keep in mind that any change to those settings WILL affect the total space used by the page, so sometimes it's a balance between your visual comfort, and page usability.
