When you press the space bar, Dreamweaver will insert a space but if you press the space bar again, Dreamweaver will not insert an additional space. This is because HTML allows for only one space between characters. HTML uses non-breaking-space characters to insert more than one space between characters. To add more than one space between characters, you can press CTRL+Shift+Spacebar or you can insert the "Non-Breaking Space" character by choosing the Insert menu, HTML, Special Characters and then choosing NON-Breaking Space.

Another option is to set a preference to automatically add non-breaking spaces when you press the spacebar. To set this preference, select the Edit menu, choose Preferences and then choose the General category. Check the "Allow Multiple Consecutive Spaces" check box. Click Ok to close the Preferences dialog box.
