Are you an engineer? Are you terrible at design? Follow this guide to get a real quick better sense of design.

I've made them into small, bite-sized rules that you can follow, cause we all know engineers love rules and sticking to them.

1. White space is your friend - Double the whitespace between stuff.

If everything is cramped together it's probably one of your biggest issues. Right off the bat, this is the first thing I start to adjust when I take over a project.
Just do yourself a favor and double the space and see how it looks. It'll probably look better.

2. Use a framework

Stop trying to custom write your CSS. You'll tell me you're "an engineer, not a designer", but you won't use Bootstrap? Come on.

Don't like the way vanilla Bootstrap looks? Use Bootswatch. Or Semantic-UI. Or Angular-Material. They're all well-documented frameworks with tons of premade layouts that you can follow for your own project to get 80% there.

3. A little type goes a long way.

In general, avoid at all costs the basic fonts. Just using a custom font will get you 80% there in most cases.

Just look at Beautiful Web Type and see how amazing that shit looks with a few background textures and some fonts.

4. Screenshots are your friend

When it comes to making your site feel less "copy and paste", there's very few things you can do that are better than adding new and custom content.
One of the best ways to do this is screen grabs or pictures of whatever you're creating a page for.

99% of the time, you engineers are creating pages for software you wrote, so I'm just going to assume that's the case and say get Clipular and grab some screenshots of whatever app you're working on and throw them into your landing page. Center those images, slap the img-responsive class from Bootstrap onto them and call it a day.

Feeling adventurous? Try img-rounded out and really blow your mind.
