                    <div class="aritcle_card">

                        </a>
                        <div class="aritcle_card_info">

                            <div class="">
                                <img src="/static/images/card_xiazai.png" alt="Felvin">
                                <span>161</span>
                            </div>
                        </div>
                        <a href="/ai/1549" class="aritcle_card_btn">
                            <span>查看详情</span>
                            <img src="/static/images/cardxiayige-3.png" alt="Felvin">
                        </a>
                    </div>
                <p><script>
function highlightSelection() {
const selection = window.getSelection();
if (selection.toString().length === 0) return;</p><p>const span = document.createElement("span");
span.style.backgroundColor = "yellow";
span.className = "annotation";</p><p>selection.getRangeAt(0).surroundContents(span);
selection.removeAllRanges();
}
</script>

<p>
  这是一个 <span data-annotation='{"user":"张三","date":"2024-05-20"}' 
                class="highlight">重要概念</span>。
