To get critiques, you must be prepared to wait for people to notice your topic...
Right then...
- Validation cannot be done for your site as it is blocked by something.
- Spacing. The spacing on the website is shocking, as it is inconsistent and all over the place, making it hard for users to find content.
- Alignment. Hardly any part of the website is actually aligned properly (the right sidebar). The alignment of divs and headings of those divs are off. Make them all to the left, or all centered...not left or a bit from the left or center. This can also lead to content not being found for users.
Note: You can use grids for the design of the website.
This should help you out with spacing and alignment.
- Images. The background of the middle of your headers does not show in Firefox, but it does it IE. This makes it difficult for Firefox users to see headings of most of your divs.
- Typography. Apart from tahoma, the only fonts you use are 'arial, helvetica, sans-serif' for everything else. Make use of serifs for headings and another font for the content...you can also throw in a third font if you have a good enough design.
- Footer. You seem to have loads of space between the content and the footer of the page...it needs to be reduced so the user doesn't have to scroll down just to see the footer text.
- Slogan. It would be quite handy if you were to get rid of the blue gradient bar underneath the nav, as it has no purpose. Then you can put the text 'Professional repair since 2005' where the 'Formely MyiPodBroke.com' is as nobody really wants to know what the site was...as they are viewing iTronics Repair.
- Login. It would be far more useful to remove the big gray bar with the 'login' on it and place a navigation link to login on the far right of the navigation, to make it more visible to users.
- Date. Nobody needs to see what day it is as they have that information available to thewm already through the taskbar of their computer or on their phone. The only real need for it is if the site depends on users seeing that information and using it someway to interact with the site.
- Donation 'Please support MyiPodBroke.com and make a donation today!'. You may need to change that...
- Contact. When I click on the contact link, I do not expect to see the name of the file to be 'about.php' when it is 'contact' on the navigation. You should also include the form on the contact (well, you have it as the about page) page and provide the information you have on 'about.php' with it.
I hope I have helped you in some way.
