For the svg image insert small icon instead an image in the text.

What if to apply the following style?

.media_title{
position:absolute;bottom:0;
}

Why do we need open button? Please remove it

should be

h1,h2,h3{
line-height:32px;
text-overflow: ellipsist;
margin:0;
}

Position controll arrows on left before the title.

Firefox has native mathml support. Thus for other than Firefox browsers a mathml.css stylesheet should be added via jquery

Apply the following styles:

body {
font-size:16px;
}
p,li,dl,dt,figcaption{
font-size:16px;
line-height:32px;
}
p{
text-indent:16px;
}
math{
font-size:16px;
}
h1,h2,h3{
line-height:32px;
}

math[display="block"]{
font-size:16px;
min-height:32px; /* instead of hight */
}

For the svg image add description: Joonis. Kaks kera keskpunktidega O₁ ja O₂, mille pinna osad moodustavad läätse pinnad. Lääts on joonisel viirutatud ja selle optiline peatelg on sirge läbi O₁ ja O₂.

For the videos please remove all desctiptions, as we don't have time to correct estonian titles at the moment.

Make gaps wider and apply the following styles.
Icons would be positioned on the right of the column.

.float-thumbnail div{display:none;}
.float-thumbnail{
background-position:center center !important;
float:none;
margin-left:number px; /* number = column width */
position:absolute;
width:55px !important;
}

section{
position:relative;
}

Resize for media frame can be draged further than the window border. Should stop at the border. It would be even better, if media frame would have a fixed minimal width.

On computer in Firefox 4 the swipe left goes further, than it should go.

All links with class "topic_blocks_list_item" open when clicked. Only with_content link should open on click. Deactivate all other links.

Let's try these parameters:

var columnsParams = {
width: 600,
minWidth: 400,
maxWidth: 800,
};

Title collaps when the textfiled is norrowed. Right now instead of title in one line user sees three lines of text.
