Home page — HTML Fundamentals — Breaking Down HTML Code Smells: How to Spot and Fix Them

HTML – the foundation of every web page on the internet. It’s a language we love, we dread, and sometimes, we just put up with it. The beginners, lovingly referred to as ‘newbies’, often grapple with understanding how to create a decent webpage without creating a hot, stinking mess. But no worries, every coder has been there!
Let’s settle one thing first — what are HTML Code smells?

What are HTML Code Smells (and Why They Aren’t Gross)

A “code smell” isn’t about a physical scent that emerges from your computer (thankfully, because that would be super weird). It’s actually a term in programming which indicates there might be a deeper problem.
Think of it as the burnt toast of the coding world. If you smell something burning in the kitchen, there’s probably something more severe going on. In coding, that could mean an inefficient or inappropriate use of codings, doomed to cause trouble down the line.
Now we’ve got that cleared up, let’s delve into the typical HTML code smells and how to fix them.

Sniffing Out HTML Code Smells

There are a bunch of HTML code smells, but some are more common and problematic than others.

Smell 1: Div-itis

As a newbie, it’s normal to get carried away stacking ‘div’ tags — a lot of them, actually. You might feel as though you’ve stumbled upon a magical wand (‘div’ tags), transforming your dangerously shaky web page into a maintained structure. But that’s a trap! Div-itis, or excessive use of ‘div’ tag peppers your page with unnecessary and complex code that only upsets the smooth functioning.
How to fix it? One word: semantics. HTML5 tags, such as ‘

‘, ‘

‘, can keep your webpage structurally sound and more dischargeable.

Smell 2: Inline Styles

Remember, how your mum told you not to mix all the colors in one painting, else it will turn into a murky puddle? That’s how Inline styles in your HTML look like. They can cause a real mess by spiking code redundancy and making maintenance a nightmare.
Instead, stick to the principle of separation of concern. Use CSS stylesheet for all your styling needs.

Smell 3: Deprecated Tags

‘Deprecated’ sounds fancy, right? But it’s just a fancy way of saying, “Hey, we don’t use these tags anymore!” Tags like ‘‘ or ” are the dinosaurs in the HTML world. If you’re still using them, it’s like painstakingly starting a fire with stones when you have matches lying around.
The fix is simple, really. Replace these archaic tags with their modern counterparts: CSS!
Remember, everyone was a newbie at some stage. By learning to recognize and correct these ‘smells,’ you’ll be a well-equipped, efficient, and confident coder in no time! The path to righteous coding is laden with mistakes and learning. A pinch of patience, a dollop of practice, and a wee bit of humour can make your coding journey enjoyable and productive. Just remember what a wise person (possibly a coder) once said: If at first you don’t succeed, debug, debug, again!
