Hiding title text on mobile only

Site URL: https://www.nickdavid.co.uk/

Hi,

I have some custom code that allows title to appear on hover on desktop. 

I have it currently so the effect is disabled from mobile as it is not necessary or helpful to ave hover there. 

But, my question is, now the mobile site is showing the title by default on mobile underneath each image.

How can I hide title from mobile, but still have my hover effect?

Here is the code:

@media only screen and (min-width:834px) {

  .yui3-lightbox2 .sqs-lightbox-meta.overlay-description-visible {
    background: transparent !important;
}
  

/* increase image transparency on hover */ 
  img.summary-thumbnail-image.loaded:hover 
  { 
  opacity: 100;
  }
/* display title on hover*/ 
  .sqs-block-summary-v2 .summary-item .summary-title 
  a{ 
  background-color: transparent; 
  opacity: 0; 
  color: #fff; 
    position: absolute;
     left: 0;
     right: 0;
     top: 40%;
     margin-left: auto;
      margin-right: auto;
 
 
  }
 

  .sqs-block-summary-v2 .summary-item:hover .summary-title 
  a{ 
  background-color: transparent; 
  opacity: 4; 
  color: #353535; 
  position: absolute;
    top: 50%;
    left: 60%;
      transform: translate(-50%, -50%);
    -webkit-transform: translate(-50%, -50%);
      -ms-transform: translate(-50%, -50%);
      -moz-transform: translate(-50%, -50%); 
    margin-left: auto;
      margin-right: auto;
 
  }
/*style title font hover for summary wall block*/
.sqs-block-summary-v2 {
.summary-title,
.summary-heading {
font-family: europa;
font-weight: 600;
font-size: 25px !important;
color: #33cccc;
text-transform: uppercase;
 } }
/*eliminates white space between thumbnails*/
.summary-thumbnail-container,
.summary-title {
margin-bottom: 0 !important;
}

}
 

Thank you for all you help.

Hi. Which title?

Hi,

/*style title font hover for summary wall block*/
.sqs-block-summary-v2 {
.summary-title,
.summary-heading {
font-family: europa;
font-weight: 600;
font-size: 25px !important;
color: #33cccc;
text-transform: uppercase;
 } }
 

The summary wall block title. The one that appears when you hover over image block
