i have two web zone i need to have one in the left to stay while the other scroll when the browser's scroll bar scrolls. any suggestions or ideas are welcome
don't know why you would do this but if you had to I would open up sharepoint designer, navigate to the page. edit the page and open in advanced mode. Look for the following tag
<WebPartPages:WebPartZone with a title attribute of zone 1, within that add a styles attribute with display as fixed:
so should look on the lines of:
<WebPartPages:WebPartZone id="g_sd23423432434sdfsd" runat="server" title="Zone 1" styles="Display:fixed;"
as you can see above all I did to zone 1 was add in some custom style to set that zone fixed to the screen. you can play around with the style as you please but I would recommend using your browser first (developer tools by pressing F12 on the browser) to play around before doing any changes through SPD.
a little guid on how to do that:
use this as a guide to use SPD on SP online to get to the page and edit.
using script editor:
