html - problems with setting to css attr field data-title, the id from javascript -


i use popup when take mouse icon, , it's working fine when text set static, need text (my case: data-title) set id javascript. how can this?

p.s. i'm try use data-title-id, there don't give me values.

html:

<div style="width:10px; float:left; padding-top:20px;"> <div class="photo4" data-title-id="time2"><img src="{{ static_url }}images/time.png" width="22" height="22px"></div> </div></div> 

css:

.photo4 {     display: inline-block;      position: relative;  }  .photo4:hover:after {     display: block;     content: attr(data-title);      position: absolute;      left: 120%; bottom: -250%;      z-index: 1;      background: #003399;     font-family: segoe ui; font-weight: lighter;     font-size: 13px;      padding: 5px 10px;      color: #fff;     border: 1px solid #333;     -moz-border-radius: 5px     -webkit-border-radius: 5px;     border-radius: 5px 5px 5px 5px; } 

the data-* attribute named wrong in css. should content: attr(data-title-id);.

also note “in css 2.1, not possible refer attribute values other elements subject of selector.” , in css 2.1 attr() function limited content property.
