Setting up Travis, Jekyll and GitHub pages

4 Comments

Update, November 2017

I don’t use this setup anymore, it might be outdated, proceed with caution.

Original post

As I already mentioned, GitHub pages do not work with the Jekyll plugins. It is a security measure. So I researched it a bit, and colleague of mine proposed a simple solution - Travis CI.

There is a great repo with instructions how to set everything up - jekyll-travis. But few steps are kinda confusing, and it took me 10 failed builds to make it work. So I’ll try to help you with those.

Plain JavaScript animated window scroll function

2 Comments

Before modern frameworks, I always used jQuery’s scrollTo method. At some point, not every project included jQuery, so I wrote simple function to animate window scroll.

I have kept copying that function from project to project. Finally I took some time, cleaned it up and published it on the npm (this is the first npm package I published).

Check the demo and read documentation of Github.

Implementing PhotoShop font sizes and tracking in CSS, points to pixels conversion

We’ve all been there - trying to get right font sizes from PhotoShop to CSS. Designers usually work with points, which are used in the print, but not common on the web. They also use term tracking a lot, which is actually only a letter spacing with different units.

You can recalculate everything by hand and try to keep track of it. But we can use the goodies of SCSS to make that process a bit easier.

Point to pixel ratio is 1pt = 1.333333px. We’ll create SASS function to do conversion for us.

And PhotoShop tracking works relative to the font size. One point of tracking is 1/1000 of the font size. For this one we’ll create a mixin.

Always use

Always try to use <button> when element is clickable, but it is not a link. Avoid <a>, <span>, <div> and other elements.

Note that display: flex works differently on buttons in different browsers, but we have easy fix for that.
