HTML/CSS : How to add Custom Banner in phpBB Style

我需要一些帮助来替换和添加我自己的 Header 到 DualCore 样式。我尝试联系该样式的作者，但他似乎不在。

如您所见，登录链接下方的右上角有一个小标题，但我在替换它和添加自己的标题时遇到了一些困难。

我要替换的部分 header 是“mainheader”，看起来像这样 "mainheader"在 overal_header.html 中您可以找到它，但我不太确定要添加或替换什么。我的横幅图片是“dep_banner.png”宽度:900 高度:145。 Common.css

最佳答案

在您包含的 html 中，尝试替换

<div class="mainheader">
<a style="display: inline-block; width: 900px; height: 145px;" href="{U_INDEX}" accesskey="h" class="logo.png"<!-- IF $LOGO_ANIMATION == 'on' --> dualcore-logo-animation<!-- ENDIF -->"></a>
</div>

与

<div class="mainheader">
<a style="display: inline-block; width: 100%;" href="{U_INDEX}" accesskey="h"><img src="images/dep_banner.png" style="width=100%"/></a>
</div>

将图像添加为 <img>而不是背景图像将更容易调整大小。更多信息 here .
