The menu on my homepage sometimes moves down the page, from its set position. This causes the image below it to shift too. Please see the attached screen shots for your reference.
Once I navigate away from the homepage (to another page of the website) and back again, both the menu and image are back in their normal positions and remain there until I leave the website. Sometimes refreshing the page makes them move back too. As I mentioned before, this shift only happens sometimes.
I've viewed the website through several browsers and the same issue keeps coming up.
I've run the HTML and CSS through the WC3 validators and no problems were identified. This is my first website though so I'm sure I've muddled something up.
Does anyone know what could be causing this?
Thank you in advance for your advice.
