Site not displaying properly on devices

I’m still having some issues with the way the site displays on devices.

On my iphone, the images on the presentation/home page seem to be stretched. They are in 16×9 ratio, and look fine on the slider and on the computer screen, but on the iphone in the ‘latest posts section’ below the slider they seem to be stretched to the width of the iphone but for some reason are not proportionally taller as well, so they appear thin and stretched horizontally.

But when you go into the posts themselves, the images display quite small, they don’t reach all the way to the sides and have a big border round them, so the photo itself is quite small, especially the landscape-shaped ones.

Also, on both phone and ipad, the post titles don’t show up. On the computer, they pop up when you hover your mouse over the picture, which is ok. But on the phone and ipad there is no mouse, so you can’t ‘hover’. If you touch the picture, you click on it and it takes you to the post. So at no point can you see the post title. This is really bad as no one knows what the posts are about? Can this please be fixed asap? I’m pretty sure this is a new ‘feature’ which is nice on the computer screen but doesn’t translate to devices. If it’s not fixed soon I will have to switch to a different theme, and I don’t really want to do that!

Thanks
Bella
