1.
when i have a text which is 2 or 3 words only to be displayed in bold and below this a paragraph starts with a vertical gap, sometimes i change the strong tag to display as block and set the bottom margin, here because there is no need for any header tags as the text is 2 or 3 words and in bold i use this method also the para below is the 1st paragraph

my code is

<strong>strong text</strong>
<p>
paragraph
</p>


strong{
display: block;
margin: 0 0 10px 0;
}


it works however i wanted to know if setting strong to display as block is a good idea or if there is any other alternative


2.
when i have for example a container div whose width for example is 500px and this div hold 5 inners divs and the addition of all these inner divs adds up to 500px, sometimes what i have noticed is only in ie6 the last div starts in the next line though the total of all inner divs is 500px with no margins or padding added to neither the container div or any of the inner divs

is there any reason why the last div starts in a new line only in ie6. also this behavior happens very rarely and most of the time it works fine in ie6.

the link for this example is at
http://sudhakargolakaram.co.in/innerdivs.html

the code is

<div class="row1outer">

<div class="col1">
col1
</div>
<div class="col2">
col2
</div>
<div class="col3">
col3
</div>
<div class="col4">
col4
</div>
<div class="col5">
col5
</div>

</div>


.row1outer{
float: left;
width: 500px;
height: auto;
margin: 50px 0 0 0;
}

.row1outer .col1{
float: left;
width: 100px;
height: 100px;
background: #777;
}
.row1outer .col2{
float: left;
width: 55px;
height: 100px;
background: #333;
}
.row1outer .col3{
float: left;
width: 250px;
height: 100px;
background: #444;
}
.row1outer .col4{
float: left;
width: 70px;
height: 100px;
background: #555;
}
.row1outer .col5{
float: left;
width: 25px;
height: 100px;
background: #666;
}


please advice.

thanks.

No it is NOT a good idea to set strong to display: block.

You also should not be formatting text to ACT as headings when they are, in fact, HEADINGS. Use the proper tags for the proper context, it's called SEMANTIC MARKUP.

Adding to that - search engines spiders DO pay attention to REAL heading tags.

well it's your own preference I guess...
but I would rather place an extra div and an entry in my stylesheet in case I need to display a non-block strong text.

and for headings, you should always use the headings tags (h1, h2, h3, etc.) instead of bolding. bolding (in terms of most SEO) should be used for your keywords. heading tags have more impact than bold (but bold has more impact that regular text). most people don't like to use the heading tags because the line height is larger (and it acts different in different browsers). the simple solution to this is to make line-height equal 100% in your stylesheet.

most people don't like to use the heading tags because the line height is larger

That should NOT be a reason either. With CSS you can style each Hx to be the exact size, font weight, font-face, etc. that you want. You should NEVER use the Hx tags based solely on their presentational qualities because you CAN control ALL of that with a few lines of CSS.
