Add text in the homepage banner in the existing module so it fit nice. I will give the text and want to be able to replicate for new banner. 3. Make the logo appear in menu and sticky menu. 3.1 Make sure the EN version if the same as the FR version. 4. Make the border disappear on each side of the footer. 5. Make the big white space disappear from under the footer. 6. Center the adress line at the bottom of the footer. 7. Add margin to the text in all content page (see the prpmedic center page) 8. In the page « traitements / plasma riche en plaquettes » adjust the text and image to fit the screen. 9. In the contact page, make sure that the form to contact the business is well integrated.
