DISCUZ X3.5兼容X3.4和之前的模板的小方法

步骤：
一、

去除漫游相关代码，修改template\模板目录\forum\discuz.htm(php)文件，找到并删除如下代码：

<!--{if $_G['group']['radminid'] == 1}-->
        <!--{eval helper_manyou::checkupdate();}-->
<!--{/if}-->

二、

修改template\模板目录\forum\discuz.htm(php)文件：

找到

{STATICURL}image/common/$online[icon]

修改为

$online[icon]

三、

将\static\image\common\目录下的dzicon.eot、dzicon.woff、dzicon.woff2三个文件复制到你使用的模板的图片目录下，图片目录为你在后台模板编辑里设置的“界面基础图片目录 {IMGDIR}”

四、

模板common文件中使用了common.css，还应在common.css最下面添加如下css

img, svg { vertical-align: bottom; }
        @font-face { font-family: "dzicon"; src: url('{IMGDIR}/dzicon.eot'); src: url('{IMGDIR}/dzicon.eot?#iefix') format('eot'), url('{IMGDIR}/dzicon.woff2') format('woff2'), url('{IMGDIR}/dzicon.woff') format('woff'); font-weight: normal; font-style: normal; }
        [class^="fico-"]:before, [class*=" fico-"]:before { font-family: "dzicon"; font-style: normal; font-weight: normal; speak: none; display: inline-block; text-decoration: inherit; width: 1em; margin-right: .2em; text-align: center; font-variant: normal; text-transform: none; line-height: 1em; font-size: 120%; }
        /* font icon size */
        .fic4 { font-size: 14px; }.fic6 { font-size: 16px; }.fic8 { font-size: 18px; }
        /* flip x */
        .fifx::before { transform: scale(-1,1); }
        /* font rotate */
        @keyframes dzrotate{0%{transform:rotate(0deg)}100%{transform:rotate(359deg)}}
        .ficr { margin-right: .2em; }.ficr:before { margin-right: 0; animation: dzrotate 2s infinite linear; }
        .loadicon { background: url("data:image/svg+xml,%3csvg xmlns='http://www.w3.org/2000/svg' width='16' height='16'%3e%3cpath fill='%23999' d='M12.2 12.2L14 14H9V9l1.8 1.8c.7-.7 1.2-1.7 1.2-2.8 0-1.9-1.3-3.4-3-3.9v-2c2.8.4 5 2.9 5 5.9 0 1.6-.7 3.1-1.8 4.2zM3.8 3.8C2.7 4.8 2 6.3 2 8c0 3 2.2 5.4 5 5.9v-2.1c-1.7-.4-3-2-3-3.9 0-1.1.5-2.1 1.2-2.8L7 7V2H2l1.8 1.8z'/%3e%3c/svg%3e"); display: inline-block; width: 16px; height: 16px; animation: dzrotate 1.2s infinite linear; }
