I don't want the word articles to be seen

Hi there!

It seems you have enabled page header within your menu item edit window. And this is why it is showing on top of the page.

Would you please check that?

If you are facing difficulty to check then give me your admin access to check and do it for you.

Best Regards

If you want the image as fullwidth and little bit below from the menu, then you can use the following code in your custom CSS:

.view-article .entry-image img {
    width: 100%;
        padding-top: 30px;
        }

You can play with the padding value as per your choice!
Hope this helps!

Best Regards

Would you please explain your need a little bit more about what you want with the menu?

Can you give me screenshot indicating that?

I have visited your link and yes your menu items are white colored there.
So here is the code you need to change your menu item color:

.sp-megamenu-parent >li >a, .sp-megamenu-parent >li >span{
color: black;
}

I have used there black color, you can use any color you want within the above code.

Best Regards
