Hi ashraf1,
1/ You can go to the site modules > Masthead then change the info for the contact us page now.
2/ To change the image, you can use the following CSS code:
.contact .plain-style .contact-information .inner .contact-left img {
border-radius: 0;
}
3/ To change the field space to a non-curvy corner, you can add the following CSS code to your site:
.form-control, .inputbox {
border-radius: 0;
}
4/ You can add this CSS Code to your site and change it:
.acm-teams.style-1 .teams-img .round-decor.bg-pattern {
border-radius: 0;
height: 50%;
z-index: 1;
}
.acm-teams.style-1 .teams-img .round-decor {
