Center with margin auto doesn't work
css, margin
Solution
Add `text-align:center;` to `.content_tuto` and it will center
Note, you have the widths `style="width: 7680px; ...` and `style=".. width: 1280px; ...` , so when you center you are centering for that width.
Problem
I use a jQuery animation in my page which adds some CSS properties and I don't understand why the `margin: auto` doesn't work. The HTML code (with style properties added by jQuery) : ``` <body style="overflow: hidden;"> <div id="tuto_wamp" style="width: 7680px; height: 923px; "> <!-- Step 1 --> <div style="height: 549px; width: 1280px; margin-top: 0px; margin-left: 0px; position: absolute; overflow-y: hidden; overflow-x: hidden; "> <div class="content_tuto"> <img src="images/install1.png" alt=""> </div> </div> </div> </body> ``` My CSS code : ``` #tuto_wamp { background: #3a393c; width: 100%; } .content_tuto { width: 100%; margin: auto; display: block; } ``` I don't know which property blocks the `margin: auto` to center the image. Thank you.
