Why Most Developers Fear CSS

Steffen Pedersen on June 08, 2019

When I started at my job, we where two front-end developers at my team. It was me and a senior front-end developer. Then the senior front-end devel... [Read Full]

Good article! I'm mostly a back-end developer, but I do guerilla front-end when I have to. Can confirm it scares me.

 
 

Thank you so much! Maybe it is a good thing being scared sometimes. Okay, Google can't help me on this one. How are guerilla and monkey work different? 🤔

 

Haha, by guerilla I just mean that I rush in and rush out and do a very shoddy job :)

 

!important

Hush. We do not speak of it.

 

Shh! The rule that must not be named. The unspeakable rule.

 

At some point someone's going to have the bright idea to add in an importance factor, like Z-ordering, and further insanity will ensue.

 

It looks like most of the fears are based on lack of knowledge. Knowing how selectors work, what is their priority, is like knowing that x has priority over + and you don't need to put parens there, for ex. Browser compatibility may be an issue, but it's not like there are no solutions that are clearly documented. So it all boils down to know your tools, I guess. Knowledge being the best cure against fear :)

 

I completely agree. There are just so many developers having a biased opinion on CSS. And there are so many with a bad attitude. I think I will use the saying that knowledge is the best cure against fear 😃

 

Jeg må ikke frygte.
Frygt dræber sindet.
Frygt er dødens forløber, der medfører den totale udslettelse.
Jeg vil gøre front mod min frygt.
Jeg vil tillade den at gå forbi mig og igennem mig.
Og når den har passeret, vil jeg vende mit indre øje mod dens vej.
Hvor frygten gik, vil intet være. Kun jeg vil være tilbage.

 

I ended up falling into mostly frontend work because nobody else seemed interested, and the work needed to be done. I think CSS is why. Backend work seems more "pure".

Trying to make things work cross-browser isn't as bad in the old days, but it's still a hazard to watch out for. Safari is usually the biggest problem IME, despite all the jokes about supporting IE.

 

Safari is the new Internet Explorer 😉 I am not even joking that much.

I think we will see a huge change on browser support in the future. There is a new thing called CSS Houdini, which will try remove these issues.

 

Houdini is actually one of my greatest CSS fears.

I'm afraid that, even if this allows you to seamlessly roll out a new type of layout rule, all this will create, ultimately, is more fragmentation in the ecosystem.

The thinking and strategy appears to be along the lines of "Just throw more JavaScript at it", which, time and again, tends to go all kinds of wrong.

CSS, like JS, is already bloated and messy, struggling to be all things to all people. Now CSS won't even be declarative in nature anymore - it'll depend on JS, and the two will fuse into a giant, hairy ball of mud.

With Web Components fusing HTML with JS, what used to be declarative, semantic markup is now unreadable gibberish - this will do the same for CSS.

The web used to be a homogenous, human-readable medium. Now every webpage will use it's own version of HTML and CSS, and no two sites will look the same.

I used to be optimistic about the web - but now, there are definitely times when I think HTML, CSS and JS are all f_cked beyond repair, and maybe we just need to start over with something much simpler that actually does what we need.

You are correct 100%. All used to be simple and uniform and clean. Now all is a big mess and super fragmented.

 

A lot of back end devs I know have little love for CSS for the simple reason that you had to write so much garbage for so long. Things are pretty different now with browsers at least trying to agree on how they interpet things like CSS. The legacy of internet explorer, and its refusal to align with other browsers, meant that a lot of what you had to learn and implement were just fixes and patches that could well be irrelevant a year or two later. Compare that to learning coding theory that will still make sense years later or with a different language and I can appreciate that many back-enders are more "reluctant" (rather than scared) to tackle front end coding.

 

You are so right! There has been so much development on CSS for the past few years. I do understand why some developers are reluctant to work with CSS.

 

I am a backend developer and I have no fear of CSS. I just find CSS to be a horrific fractal of bad design (yes, I stole that phrase from elsewhere.) It is a damn shame that those who designed CSS did not have more foresight.

So I am a backend developer by choice because I would prefer to spend my time building buildings rather than digging holes in quicksand. #justsaying

 
 

Lack of ability to encapsulate. Working with CSS on even a moderate sized website is like programming a large complex application in a programming language that only supports global variables. Which is bad with one developer, but far worse when there are many working on the same project.

You are able to encapsulate. I often use the architecture ITCSS with naming convention BEM 😃 I use it at a large company, and it's easy for other developers to wrap their head around the concepts.

Actually, you are not able to encapsulate in CSS. What you are talking about is like the ostrich sticking its head in the sand so it cannot see its potential attackers. But its potential attackers can still see it.

The problem with "encapsulation" in CSS is it only works when everyone on the project uses it and uses it the same way. There is no way in CSS for me to write a "module" (for lack of a better word) that someone else cannot override and break with later CSS.

Yes, if you are using CSS you should absolutely employ (something like) ITCSS and BEM, but those are merely ways to reduce the pain of the symptoms of the disease, they do nothing to cure the disease itself.

 

Regarding the title pic: as a front end dev, I'm pretty scared of floating :D

I was left as the only dedicated front end dev in a company once too. It didn't decrease the bus factor to 1, since we exclusively worked with a 3rd party product, but I felt that I was the only one thinking about innovation in our front end.
I talked to the boss and got the permission to have internal workshops. Turns out, if you take the time to explain flex or svg hands-on, most back end guys can comprehend it pretty quickly and take their knowledge to production.

 

I love hearing stories like this one 😃 You are right. I have also explained CSS to back-end developers. Most of them have learned the basics of CSS in school at some point.

 

I'm finding more and more new developers see CSS as voodoo. At first this didn't make sense to me, but the points you bring up are the root cause. If you didn't cut your teeth on inline style attributes, and then get CSS support, and then start working on old browser compatibility bugs... a lot of it just doesn't make sense. It's almost a series of stepping stones, and those of us that experienced them when they were laid know what to look out for – everyone else is just constantly getting "gotcha'd" and it's got to be very offputting.

 

The biggest fear comes from the fact that debugging or troubleshooting isn't easy with CSS especially when complex layouts and things like floats and transformations are involved.

Add to that the fact that you can have responsiveness, various levels of styling (external sheets, <style> tag, element property) and browsers can also have subtle differences in rendering, it easily gets mind numbing!

Front-end debugging with html/css is still an evolving science compared to back-end debugging which is quite straightforward in comparison.

 

Great article. I wouldn't use the word "scares", but I have a hard time picking names for classes, especially when there are child elements or wrappers involved. Somehow I don't seem to get that problem in backend context very often.

 

I think naming in general can be tough 😲 In CSS there several different ways to help organising. There are ITCSS and BEM, which combined is called BEMIT. There is also Atomic CSS, which I haven't tried out yet 😃

 

I have only heard about BEM so far, I'll look into others. Thanks :)

 

i'm backend dev. i can write CSS but to build good and nice web from scratch is hard. that needs skill as same as backend build database structure and CRUD.

from my point, the scare thing is when write CSS from scratch and when you have complex element and you find something wrong with the CSS that the element not displayed properly. there is no error log and you cannot debug it.

 

I remember building something from scratch was really tough in the beginning 😃 There are some tricks to help you debug CSS. With linting you can catch more obvious errors. But no, plain old CSS doesn't give you much help 😃

 

This is a lovely read Steffen. Thanks for it.

As someone who has been kept away/kept myself away from CSS, can vouch for both how easy and how important it is to understand stuff like specificity/cascading after building something from scratch with plain grids and mental models of the concepts above.

Good job :)

 

Actually, the main problem of CSS is the metodologies we use to develop. They force us to do mistakes and technical debt. Over the time, anything becomes unmaintainable. That's where the functional CSS shines all over you minid.net/2019/04/07/the-css-utili...

 

Great article, right on target. We use SCSS 4.6 with Wellington preprocessor SMACSS compliant. GoHtml5 templates. No JS now with WebAssembly. CSS can now be well organised and reusable, it is a different world.

 

Thank you! A lot have happened in the past few years 😃

 

This certainly was worth the read. Very true, especially the part about changing something somewhere an it affecting many other parts. Even though I had these fears, I really couldn't have put them into words as you've done. I just use frameworks and learn enough to do what I want that those frameworks I use don't do.

Now I know what my exact fears are, I can face them

 
 

was helpful. I did not know about @support, although I constantly work with css, there is nothing complicated at all (well, except for the latest fashionable innovations such as transition and others, where you can already just program the interface behavior - yes, it’s confusing and complicated if you don’t constantly practice track the latest trends.

 

What I disliked most about CSS was layout, but with Flex and so on that's improved a lot. But before the modern layout techniques (and even still, I have to confess), I often had a hard time understanding why my layout was broken. Even when looking at Chrome Inspector it often wasn't clear who or what was the cause!

On the other hand I'm surprised to hear that cascading is such a big deal, because most devs are familiar with inheritance as a concept.

Nowadays what I fear about CSS is its sheer complexity, just the huge size of the "API surface".

 

Box model? Grid? Float? How does this darn thing work? I can't make CSS do what I want easily. That's my issue.

 

MDN Web Docs often has some great examples. But I know the feeling 😉

 

Man, I feel like the opposite, with design Since I don't have someone handing me a design, coming up with or thinking of one is hard. I'm comfortable with very basic designs, and those will get the job done, but they don't really stand out.

I guess it's a weakness I hope to shore up. But, I often feel caught between where to spend my time. Learn more design oriented skills, or more programming oriented skills. Never enough time in the day, I suppose. It sucks.

 

I think mainly because IT TAKES A LOT OF FREAKING TIME to do stuff with CSS. It's like programming in Assembly. Horrendous.

 

It really depends on what you're making. But yes, it can take a lot of time 😃

 

Is it really necessary to insert emojis in the text of such an article? It's very distracting, and detracts from any serious points it's trying to get across.

 

Thank you for the feedback. I will reduce the amount of emojis in the next article. I was going for a more informal tone.

 

Most developers like CSS

It's a vocal minority that casts shade.

 

I think you're absolutely right.

 

CSS is magic and I love it. but it's not rocket science.

 

Nice overview, thigh there is one failing... Css IS magic 🤓😉💫

 

We're not developers. We're magicians 😉🎩✨

 

good article ! i love CSS is so fun to use it ! i think the lack of knowledge make developper in general fear CSS

 
 

I'd prefer they fear CSS rather than writing lots of !important.

 

it's about time before we see another system to replace it..

 
 

I think most back-end dev are scared on what CSS used to be, not knowing what you 'actually can do with it' now.

 

I see CSS much alike iptables rules.
