The free Jimdo plan offers:
Premium features include more storage, faster support and more. The personal plan costs $90/year.
Jimdo uses a hybrid drag and drop editor - you can move text and images around, but you must stay within the confines of the template.
Jimdo can automatically create a mobile version of your site, if you check the box to activate mobile view (checked by default).
How much code do I need to know?
None, but: you can actually build your entire page using an HTML editor, if you want to. You can also add code to the <head> tag of your website, which is a unique feature among these tools.
Can I choose my own colors and fonts?
Yes, but: the amount of customizability you have depends on which layout you choose. You will be able to choose from eight fonts, and you cannot add any more.
Can I add professional features like a photo galleries and image sliders?
Jimdo allows for outside code, so you could create these features in a third party application and paste them into Jimdo. While there are some apps like Twitter integrated, there are fewer built-in fancy features.
