我创建了一个输入，但在Chrome和MS Edge中，如果你点击该输入，它会在输入周围显示一个丑陋的黑色边框/框架。在Firefox中，边框/边框不会出现。如何在Chrome/MS Edge中删除此边框？

<input type="text" value="Text" title="" readonly=""
style="display: block; margin: 0px; position: absolute; height: 26px; min-height: 26px; max-height: 26px; resize: none; border-width: 0px; font-family: Arial; font-size: 12pt; line-height: 12pt; color: rgb(0, 0, 0); cursor: text; background-color: transparent; left: 0px; top: -2px; width: 194px; min-width: 194px; max-width: 194px; padding: 2px 3px 0px; text-align: left;">
</div>
</body>
</html>请添加以下css：
input:focus{
outline: none;
}
这将删除默认值并添加一个类似于Firefox上的边框。此外，练习结构与表现的分离。
