Hi, parallel this next question.

Page use MLA templates:
[justified_image_grid ids=1476]

JIG show image and mla_gallery show document.

Code:

<style type='text/css'>
	#[+selector+] {
		margin: auto;
	}
	#[+selector+] .gallery-row {
		float: [+float+];
		margin-top: 10px;
		text-align: left;
		width: [+itemwidth+]%;
	}
	#[+selector+] td {
		padding: .5em;
	}
	#[+selector+] .gallery-row td.gallery-icon {
		width: auto;
		height: auto;
		vertical-align: top;
	}
	#[+selector+] .gallery-row .gallery-icon img {
		width: 76px;
		height: 72px;
	}
	#[+selector+] .gallery-caption {
		margin-left: 0;
		vertical-align: top;
		width: auto;
	}
</style>

Long text and much information is very good when want search engines found documents. Long explanation tell much also to user.

But:
– Page is not good-look
– Too much text
– Not mobile-friendly

Easily I can edit it explanation text “first 100 character tell basic information” (100 = 150? 120? 250?).
So, any idea? “lorem ipsum, liiba laaba, this is very good and beautiful product” <…show more>.
“Show more”:
– Mouse over or click show more. When user activate this “show more” it open all text but not close other text on the page.

Any idea is this possible?
