After calling the smart tag in Empire CMS, how to output the new logo behind the title?

1. CSS code:

.newpage::after {
    content: "新";               /* 显示的文字 */
    display: inline-block;
    color: #ff0000; 
    font-weight: bold;           
    font-size: 14px;             
    margin-left: 8px;            
    animation: gentleJump 1s ease-in-out infinite; 
}

@keyframes gentleJump {
    0% { transform: translateY(0); }
    50% { transform: translateY(-3px); } 
    100% { transform: translateY(0); }
}

2.php code: determines and outputs the value of the `class` attribute.

<?php if (time() - intval($bqr['newstime']) <= 259200){echo 'newpage';}?>

3. Complete Dynamic Tag invocation code.

[e:loop={1,8,0,0}]
<li>
<a class="<?php if (time() - intval($bqr['newstime']) <= 259200){echo 'newpage';}?>" href="<?=$bqsr['titleurl']?>"  title="$bqr['title']"><?=esub($bqr['title'],15,"...")?></a>
<span class="carousel-date"><?=date("Y-m-d",$bqr[newstime])?></span>
</li>
[/e:loop]
