From 7355db94d62e84706bd5ae5ff21c007865fc5381 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?J=C3=A9r=C3=A9mie=20Astori?= Date: Thu, 22 Mar 2018 01:17:44 -0400 Subject: [PATCH] Improve UI of previews - Remove margins around thumbnails and images, increase radius, etc. for a fresher look overall - Increase preview body contrast just enough to pass AA standards - Add a `More`/`Less` button to expand previews that take more than one line. Button is added only when necessary - Use a zoom-in cursor on hover for thumbnails - Improve preview message errors --- client/css/style.css | 103 +++++++++++++++++++++++++---------- client/js/lounge.js | 4 ++ client/js/renderPreview.js | 38 +++++++++++++ client/js/utils.js | 6 ++ client/views/msg_preview.tpl | 53 ++++++++++++++---- 5 files changed, 164 insertions(+), 40 deletions(-) diff --git a/client/css/style.css b/client/css/style.css index 0c6f9947..c5e8baff 100644 --- a/client/css/style.css +++ b/client/css/style.css @@ -238,6 +238,7 @@ kbd { #chat .nick .from::before, #chat .action .from::before, #chat .toggle-button::after, +#chat .toggle-content .more-caret::before, #version-checker::before, .context-menu-item::before, #help .website-link::before, @@ -1332,75 +1333,112 @@ kbd { color: #f00;
