Why has the font size suddenly increased in size? This has nothing to do with my browser; all other websites are fine?

Hello there, Ghami. It can happen sometimes that while the other websites are fine, the other one that has a big font size has been accidentally zoomed in. 

To reset the font size on your dashboard, press Ctrl + 0 to return it to normal. If you'd like to adjust the font sizes, you can hold down the Ctrl key while pressing the + or - keys or scroll up or down with your mouse wheel. If you’ve already tried these steps and they haven’t worked, I can suggest some other options.

You can also change the font size in your browser's settings. Keep in mind that any changes will apply to all websites you visit in that browser:

Google Chrome:

1. Click the three dots (Ellipsis) in the upper right corner.
2. Select Settings.
3. Under Appearance, adjust the Font size and Page zoom settings as needed.

Mozilla Firefox:

1. Click the Hamburger icon (three horizontal lines).
2. Choose Settings.
3. Update the font size according to your preferences.

Microsoft Edge:

1. Click the Ellipsis in the upper right corner.
2. Go to Settings.
3. Click on Appearance on the left side corner.
4. Scroll down to Appearance and adjust the font size to your liking.
