The button itself has the 'search' label, the input box and then the search button.
I have tried using various css changes such as margins to either get the button to stop sticking to the search input box and give it some breathing room when in a mobile view (small resolution) or get it to spread out lengthwise just like the main menu above.
Altercations to the search button while in the mobile view works but it also aligns it incorrectly it when in a wider/full resolution. I'm not sure what tags would be suitable to get around this.
The link above is the website on the search page.
