HTML code to modify a page width

I recently activated a new WP theme. Unfortunately I can't modify the width of the fullwidth pages. I'm searching for an html code I can place around my page content that will allow me to control the page width. I've tried a few different codes including the following, but nothing has worked so far:

<table width="760" border="0" align="center">
content here
</table>

Any suggestions?

 

Well, what you have above is only going to make it 760 pixels wide… try making that 100% instead of 760px and see what happens. I'm assuming this is table based or are you just trying to add a table? If it's not table based this probably wont do much and you'll have to edit the CSS file.

 

You can edit the CSS files to create a wrapper on the page and have all your content inside that.

You will have to create a div in the PHP files too and close it within the body tags.

 

Your site may contain css properties so far I hope according to your ask. you have to change html and css property at a time..try your best.

 

You can't control page width with HTML or CSS. All you can do is control content width.

If you want to control page width, you will need to use Javascript or some other language.
