Web Design Tools
On the Design tab, you can add a logo, switch templates, and use the Style Editor while creating your website. The latter lets you change your template's colors and fonts to taste. Squarespace review offers a good amount of customization in this area, letting you choose from hundreds of fonts and colors using a gradient color-picker. Colors are adjustable for every type of button, header, and link, including social buttons. Note, however, that colors and fonts only apply to the content types. You can't change fonts and colors for different instances of a header, for example. The Style Editor also lets you adjust spacing and padding for buttons, images, and titles.
Working With Images
Not only does Squarespace offer integrated Aviary online photo editing for your uploaded images, but it also lets you search for, preview, and buy licenses to use Getty Images professional stock photography on your site. The licensing cost for my test images was $10—pretty reasonable. Unlike Wix and 1&1 MyWebsite, however, Squarespace doesn't save a repository of your uploaded images for use elsewhere on your site(s). Instead you have to upload an image every time you want to use it.
You can add a gallery to any page, or add a gallery page, which takes its design from your template—there aren't any customizations to the gallery's appearance if you go the page route. On-page galleries can appear as carousels, grids, slideshows, or stacks, and they offer behavior customization choices, such as showing the title and description when the mouse is over an image, transitions, and a lightbox for the grid gallery type. You can also adjust spacing, but you don't get the degree of control over the appearance of your galleries that some other site builders offer. This enforces good design, but at the cost of creativity.
Blogging With Squarespace
You can add pretty much any type of content to a blog post that you can add to any other page you build. Squarespace also lets you save and schedule posts for publishing later—an important feature that 1&1 MyWebsite lacks. Posts include a heart icon for liking, comments, and a share icon. You can enable an RSS feed for your blog, and use email to write new posts when you're afield. You can even set up iTunes podcasting integration.
