Hi there and welcome
Sorry, the previous expertmis understood and left the conversation.
For this to work you have to have a mac I know you said clearly you did not but I am only telling you the reality of the situation. For you to achieve what you want to do you need a mac
On your device, head to Settings > Safari > Advanced
You’ll find the Web Inspector toggle there.
Once enabled, you’ll need to physically connect your iPhone or iPad to your Mac. Yes, this is Mac only at this point. In Safari’s Preferences pane under Advanced, check the Show Develop menu in the menu bar checkbox.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
