MG 1.1 Display the whole title

Hello guys !

I would like to ask if any of you know a way to show the whole title of media.

I use this code for the sidebar new posts blocks, can anyone help me to modify it ?
/* Show whole title in sidebar New Posts block */
.sidebar .threadListItem .title, .threadListItem .additionalRow {
  white-space: normal !important;
Thank you
