如何添加媒体查询以使图像的填充更小？

Question

我正在做一个小画廊，我刚刚弄清楚如何使用 Salvattore（类似于 Masonry）。我遇到的问题是，当我缩小网页时，填充仍然是 10px，我希望它是 5px，这样所有 3 列仍然可见并且填充看起来仍然不错（有点像 Pinterest） .我尝试了媒体查询，但它不起作用。这是我的 HTML 和 CSS:

Answer 1

您的@media 标签格式似乎不正确。试试这个“@media only screen and”代替你的“@media”并检查一下 https://www.w3schools.com/cssref/css3_pr_mediaquery.asp 。希望这个帮助
