Question: There's this website I've been working on for a client of mine and I've been working on the mobile layout. I decided to use a flexbox layout for the overall website, but for some odd reason, the stock android web browser for 4.4.2 isn't loading any of my elements that are using flexbox. Chrome for Android loads all my elements using flexbox just fine. I can't be too sure of what's happening, but any help that can be given would be great. All my code is on "hoopactivation.x10.mx" if you use the developer tools. If need be, I can also post my code on here if neccesarry (Which will probably happen anyhow. I'm just not near my laptop right now).

Answer: 
Instead of declaring autoPostBack as true in your event handler, try to set it in DropDownList declaration like bellow:

```
<asp:DropDownList ID="ddlBookCategory" ... autopostback="true" ... >
...
</asp:DropDownList>

```
If you want to set `ddlBookCategory.AutoPostBack = true;` dynamically then set that in pageload event.
