Paul Gauguin, Pastorales Tahitiennes, oil on canvas, 87.5 × 113.7cm Getting a nice UI/UX on a SaaS app can be a real challenge for developers that know how to code, but struggle with design. I come from a software engineering background and while building and blogging about it, I got a lot of questions about the UI framework I was using. https://checklyhq.com Spoiler: It’s just Bootstrap and some Vue.js 😱! Here are my tips on getting the spit & shine on your UI. Regretfully, this will not be easy. Life is pain 😥. Entries are listed in order of (very) subjective importance. 1. The eye is more important than math or code All your developer synapses will be firing at this one. But sometimes the exact grid and the equal divisions on margin and font sizes just plain look bad. Trust me , I studied Computer Sciences but also Art History 😇 (actually true!). On a 12px grid? Header looks better with a 13.7px margin? Do it. For my brand logo I tweaked the heights and widths of its various parts until it “felt right”, screw what the CSS says. The Checkly racoon mascot, logo text and beta callout are all slightly bumped up, in or out a few pixels to make them look aligned in the center What works mathematically doesn’t always work optically. This video is also enlightening. 2. Forms, modals & tabs solve 99% of your use cases Using sites like Github, Travis, Stripe, Digital Ocean and even AWS should drive home one important lesson: Form based pages with tabs for sections and modals for the more complex and context sensitive interactions solve 99% of your issues. Even in 2018. Edit page using tabs, a form an a button that triggers a modal. When trying to create a screen, I always fall back to this pattern. Rarely does it not solve the issue in the most simple and elegant way. 3. Double your white space everywhere My number one tweak to my CSS is adding more white space where there already was quite some white space. White space solves a ton of your information ordering and visual hierarchy issues. On vertical white space you can go totally nuts because . Landing pages are a good example where you can ladle on the white space. people don’t mind scrolling Checkly landing page with a lot of vertical white space To not get lost in padding and margin jungle, use these simple rules. Create a $spacer variable in your SCSS, SASS, Stylus or whatever CSS preprocessor you are using. Bootstrap uses 1rem by default. Use multiples of that $spacer in you margin and padding definitions. Again, don’t be afraid to mix up the divisions between even or uneven. If it looks better it is better, i.e : 1.5 * ; : 1.2 * ; margin-bottom $spacer padding-top $spacer 4. Just use Bootstrap and customize it a bit Maybe this tip should have been at number one. Most of the advice above and the next tips in this post are solved in . Bootstrap gets a lot of crap about sites looking samey and still using jQuery. Twitter’s Bootstrap These criticisms are easy to work around and they distract from the incredible amount of well made decisions in the framework due to its age and the experience of the people working on it for years. Bootstrap everywhere So how to dodge if you’re building an SPA? Simple, just use something like (the awesome) if you are using like me, or if you’re in land. jQuery https://bootstrap-vue.js.org/ Vue https://reactstrap.github.io/ React And how to dodge that canned Bootstrap look? Two options: The real way: start customizing by editing the metric tonne of Bootstrap variables. Small tweaks go a long way — more on that below. The docs on the give you all you need to get going. Bootstrap site The lazy way: buy a theme and reuse the(S)CSS. There’s some pretty decent theme’s on Themeforest’s . Admin Template section Other frameworks like , are also great and look shiny and “modern”. However, I found they rarely offer the same cross browser compatibility and robustness once you start prodding around. I might be wrong. Bulma Semantic UI 5. Colours matter more than you think Many developers completely underestimate how much colour determines the identity of a site/brand/product. is a great example. It is mostly white, has a very specific font — more on that later — and a very recognisable green brand colour (#018f69). Used consistently, it makes Medium instantly recognisable among the zillion other blog sites. Then there is Heroku purple (#79589F), Amazon orange (#FF9900)…you get it. Medium Medium, Heroku and AWS in three colours. Notice the pattern: A high visibility colour, coupled with a high contrast colour for text and a low contrast tone for borders, backgrounds etc. brand dark gray Tweaking the colour pallet is so easy and immediately sets you apart from all the non-customized Bootstrap sites. Here’s is Checkly’s file. Notice the and the various gray tones. _colors.scss brand-primary A modified Bootstrap colour scheme. The purple is still the default. Not sure what colour fit with all the others? I found a pretty handy tool to find nice complimentary hues. Adobe’s colour wheel 6. Fonts matter more than you think Fonts are like music in films. They come with a ton of even when they are rarely in the main feature. A bog standard scene of a man walking along some grassy field can convey victory, sadness or suspense just based on the soundtrack. Similarly, your site can be serious, business-casual or leisurely just based on the font. Try sticking Comic Sans on a banking site and watch the world burn. character, intent and emotion is hard to beat to start exploring how fonts resonate with what you are trying to say with your design. Small tip: use the “custom” text option to use any text that is relevant to your project. Google Fonts Google Fonts with custom text option For Checkly I chose a somewhat popular, non-free, font called Fakt Soft Pro. This font straddles the middle of the serious/leisure divide: exactly what I tend to express in Checkly’s product marketing: easy and friendly to use, but very serious in its application and problem solving ability. 7. TEXT EVERYWHERE In a typical SaaS site, you can never really have too much text. Not the long copy “War and Peace” type text, but more the right words in the right format dotted around your page. This can get messy, so getting a “visual hierarchy” for all your text elements is SUPER important. And you have WAY more text elements than you think. Let’s break down a typical screen: Different text types on a typical screen & chop the page up into digestible sections. Think to . Headers sub headers h1 h6 tell people what specific input type they are dealing with. Normally small, handle uppercase pretty well. Labels or just a paragraph (with element) tells people what something does when it is not immediately clear. This should be your “normal” baseline font. Inline help p are just a sneaky way to get more inline help in without turning every page into a declaration of independence. Use liberally against a contrasting background. Tooltips kinda only work on text field inputs, but are again ways to sneak in more help text without cluttering up the place. Lower contrast is fine to offset the actually text the user types in. Placeholders can take icons, or can be uppercased. Depends on your style. I personally tend to go light on the icons. Also see Buttons https://grumpy.website/post/0Px1O7Ukl Rule of thumb #1: The larger a font, the skinnier it should be, the smaller the fatter. Rule of thumb #2: HTML already has a visual hierarchy built in: up to and then For each element, change up at least two of the following attributes: in such a way that each element is at least different in two ways from its neighbours. Then just consistently use to . Also good for SEO! h1 h2 h3 h6 p. font-size, font-weight, margin-bottom, letter-spacing, text-transform: uppercase h1 h6 8. Steal So you thought I came up with these pages of wisdom by myself? Ha ha ha…sniff…No. I stole most of it from the from some great SaaS companies. “Good artists copy; great artists steal” goes the (totally overused) saying…but REALLY great artists tell you whom to steal from! Here are my favourites: insanely generous open style guides MarvelApp Heroku Auth0 Need more research? Here is a site that collects all of ‘m . It’s just nuts that you get to benefit from all the insights, learning and design talent at these companies. Learn, observe and maybe steal a little bit of inspiration and best practices. Styleguide.io 9. HTML emails are terrible Probably worth a full post, but making nice HTML emails is way harder than it should be. It’s HTML tables all the way down. No way around it. In general HTML emails fall into two categories: Newsletters, welcome messages, promotions etc. They have some level of personalisation, but the content is 99% the same for everyone. Mostly anonymous: transactional messages based on specific user accounts and user’s actions in your app. For Checkly these are for instance the alert messages for checks with specific response times and error messages and a weekly summary email on how each check for each account did in the last seven days. Mostly data driven: For the first category, try to just use Mailchimp or similar services. You can add a bunch of personalised data items and it will serve you well. You will age less. For the second category, I went on a wild goose chase to find the one framework or tool that allowed me to code HTML emails similar to how I build web app screens. This is what I ended up with: I use the pretty great and its pseudo HTML markup. mjml.io I use the also pretty great to actually code the templates so I can use . All Checkly HTML is actually coded with Pug templates. html-templates.js pug In my Webstorm editor, this looks as follows: An HTML email template WITH NO TABLES IN SIGHT The awesome thing is that it makes designing and editing these types of emails a lot easier. You can use the Pug logic functions like statements together with partials and the mjml.io tags that hide all of the nested HTML tables. if 10. From mock to code At former jobs I had Real Designers™ and Real Front End Developers™ and we had people worrying about brand and copy and style guides. Most customer facing web stuff went through the following process: Brand/Marketing sets identity Designer designs web & mobile screens in Sketch Sketch is further developed in Framer and/or Zeplin Front end developer turns designs into code Not all of these steps are always necessary for each iteration or each project. However, if you are somewhat handy with Sketch or a similar tool, I would recommend at least FULLY designing one or two screens before you start coding. Not ALL screens. Not every modal or interaction. Just use the correct brand colours, the correct font and try to get the margins and white space right. Consider it your poor man’s version of the full blown UI style guides mentions earlier. Doing this will considerably cut down on your development time and give you a guideline for all other screens.
