1) You want a text link and not the button? You can inspect the source code and find the button HTML and remove the icon so like this:
<a href="#" class="fw-video-link fw-video-link-icon " data-video="http://player.vimeo.com/video/107480792?title=0&byline=0&portrait=0&autoplay=1">ADD YOUR TEXT</a>
2) That’s the logo. You want to remove the logo? Use this CSS:
.full-center #logo {
display: none;
}
3) What page do you see this on?
4) The images are set to fill the width / height space in relative proportions. You would need to adjust your image proportions.
