    ...with the new look. I am also adding two completely new pages. I will provide the text and images; your job is to build the pages so the content looks sharp on every screen size, loads quickly, and matches the overall style of the rest of the site. A small functional tweak is required as well: several call-to-action buttons should change colour on hover or click. Use clean CSS or lightweight JavaScript that I can maintain easily. Deliverables: • Redesigned home page • About page layout and colour-scheme update • Two new responsive pages built with my text and images • Button colour-change interaction • Optimised, cross-browser-tested files ready for deployment Please send me a quick outline of your approach and the timeframe you need once you h...

    My c...text across all existing pages without breaking layout or SEO structure. • Replace the specified images and ensure each is optimised for speed and retina displays. • Modernise the visual design—cleaner typography, balanced whitespace and consistent colour usage—so the site feels cohesive on desktop, tablet and mobile. • Introduce any necessary front-end or back-end tweaks (think HTML, CSS, JavaScript, or light CMS edits) to streamline navigation, boost load times and add small interactive touches where they make sense. Please base your quote and timeline on the tasks above. If you need anything—from access credentials to a staging environment—let me know and I’ll provide it right away.

After installing a session recording app (Propel Replays & Heatmaps), I can clearly see that many customers are getting JavaScript errors during cart and checkout.

    My skip-hire website is already live; it simply needs a professional front-end polish, not a rebuild. Homepage first: please tidy the section arrangement, align the visual design elements, and straighten out the text and content formatting so everything sits neat...messy. Clean it up or replace it with a simple, reliable version that matches the refreshed styling and works on both desktop and mobile. Speaking of mobile, the responsive version must feel just as solid as the desktop view once you’re done. I expect the whole tune-up to take no more than three to five days, so please only take this on if you’re confident you can meet that timeline. HTML, CSS, JavaScript (or a framework you’re comfortable with) are all fine as long as the final code is clean and ea...

Think streamlined menus, intuitive calls-to-action, and modern, responsive styling built with clean HTML/CSS and lightweight JavaScript (or the equivalent in WordPress/Shopify if you prefer). When users land, they should instantly understand where to click next. Online Booking Link An always-visible “Book Online” link or button must be added and tested across desktop and mobile. It should hook into my existing booking system via embed or API so that customers can reserve a slot without extra ste...
