Customizing web page

I like to customize the glinet admin web page by changeing. ““GL-inet admin panel”” in line 4 of /www/idx_vue.html to ““routermame1 gl-inet”” so it reflects the routername in my web browsers tab.

also I like to change /www/src/temple/login/index.html and include the router name on the login page itself by adding the servername and version # to line 20 like the following
““routername1 3.105 {{t($lang.login.adminPsw)}}””

found a chinese character on line 12 of v3.105 with the following in index.html
“”" “”"
I am unable to view it in this web page script but it is posted above this line

The web is using vue. I don’t know how to change it.
