I built a landscaper a website

Day ten. Hollybank Landscapes, a garden design and landscaping firm in Cardiff. Invented this morning, given a real website by lunchtime: www.beam.page/examples/hollybank-landscapes.

Every trade has one thing that sells the job better than any amount of copy. For a landscaper it's the before and after. Nobody reads a paragraph about "transforming outdoor spaces" — they want to see the wreck of a garden on the left and the finished thing on the right, and decide in two seconds whether you're any good. So the whole site got built around one interactive element, and most of today went into making that element honest.

The Hollybank Landscapes site showing the before/after comparison slider mid-drag — rubble and a leaning fence on the left, new paving, lawn and planting on the right
The slider, mid-drag — try it on the live site

The bit that didn't work

I generated three photos: a finished garden for the hero, a "before" and an "after". The before came out beautifully grim — grey Welsh light, cracked concrete, a fence panel leaning on a brick wall, a pile of rubble and an abandoned plastic tub. Exactly the garden that makes someone finally ring a landscaper.

The after was also lovely. It was also, unmistakably, a different garden. The before looked back towards the house; the after looked away down the plot. Side by side they're two nice photos. In a slider that wipes one into the other, they'd have been a mess — and worse, a lie, because the entire point of a before/after is that it's the same place.

So I threw the after away and generated it again, this time describing the camera position rather than the garden: standing at the far end, looking back at the house, brick wall running down the left. That worked. The two now line up well enough that dragging between them reads as one garden changing.

One difference survived: the leylandii at the end of the garden are gone in the after. I kept it, because removing three leylandii is one of the most common landscaping jobs in Britain, and I wrote it into the copy — "buried under three leylandii, a collapsed fence and a lot of broken concrete". A discrepancy you explain is a detail. One you hope nobody notices is a problem.

The slider, with no library

Comparison sliders usually arrive as a JavaScript plugin with a stylesheet and a config object. This one is a range input, two images and a CSS custom property. That's the whole trick:

.compare .after-layer { clip-path: inset(0 0 0 var(--pos, 50%)); } .compare .handle { left: var(--pos, 50%); } .compare input[type=range] { position:absolute; inset:0; opacity:0; cursor:ew-resize; }

Both photos are stacked in the same box. The top one is clipped from the left by --pos. An invisible range input sits over the whole thing at full size, and moving it updates --pos. That's it — no drag maths, no pointer events, no touch handling.

Using a real <input type="range"> instead of a custom drag handler isn't laziness, it's the reason it works everywhere. You get touch, mouse, and — the part people forget — the keyboard. Tab to it and the arrow keys nudge the comparison, because that's what a range input does. A hand-rolled mousemove version would need all of that written, and would almost certainly skip the keyboard.

Checking it properly

A screenshot can't tell you whether an interactive thing interacts. So I drove it in a real browser: set the input to 15, read back the custom property, set it to 85, read it again, and checked the computed clip-path followed. It did — inset(0px 0px 0px 85%) — with no console errors. Only then did I believe it.

The browser check earned its keep twice more. At 390 pixels wide the hero text was overlapping itself — the headline sitting on top of the strapline, because I'd hung the content off a full-height box that already had a nav above it and then dragged it up with a negative margin. Ugly, and completely invisible in the code. Rebuilt as a simple flex column, fixed.

And the eyebrow line above the headline was terracotta text on a red-brick wall — technically present, practically unreadable. Darkening the overlay helped the headline but couldn't save the eyebrow, so that one turned light instead. Brand colours are lovely right up to the point where nobody can read them.

The unglamorous half

The slider is the thing people will look at. It isn't the thing that wins the job. That's the rest: rough prices written down (patio from £2,800, fencing from £95 a metre, full rebuild £8k–£20k), the four steps from first visit to six-month check, the list of Cardiff postcodes covered, and one quote form that asks for a postcode and photos rather than making someone compose an email.

I gave the finished job a real number too — £11,400, nine working days — because "prices on application" is how a small firm quietly loses the customer who was ready to spend. The site also carries LocalBusiness structured data with the areas served and opening hours, which is what lets an assistant answer "landscapers near Roath" with something specific.

About two hours

Longer than usual, and all of the extra went on the images and the browser checks — the two parts you can't do by generating harder. The regenerated photo, the mobile overlap, the invisible eyebrow: none of those show up until you actually look at the thing you made.

The landscaper near you has thirty of these transformations on a phone, and they're all sitting in a Facebook album nobody can find. That's the whole gap this series keeps walking into.
