Redirect Blogger 404 Error (Page Not Found) To Homepage

Whenever, by mistake, we or a user misspells an URL inexistent in our blog, it automatically redirects to the 404 error page (page not found). A message like this would appear:

"Sorry, the page you were looking for in this blog does not exist."

And probably this will not make a good impression on the greatest potential users of our blog. Before the user clicks the back button or close the window/browser's tab, thus leaving our site forever, we may want to redirect 404 error in Blogger to a page, where are chances that the visitor will continue reading our blog.

One of the most used methods is the "meta refresh" but the problem with this method is that it breaks navigation (doesn't allow returning back). In this case, the best method is by using Javascript which will be shown below.

Redirect Blogger 404 Error with Javascript

First of all, go to your Blogger dashboard and then to Settings > Search preferences > Custom Page Not Found.

Copy and paste the following code:

Sorry, the page you're looking for in this blog does not exist.
You will be redirected to homepage shortly.
<script type = "text/javascript">
BSPNF_redirect = setTimeout(function() {
location.pathname= "/"
}, 5000);
</script>

The message which is going to be displayed can be edited as you want. If you are willing to redirect your blog 404 error page to another page other than your home page, just replace pathname to href and / with the url of your page. And finally, the number 5000 is the delay expressed in milliseconds. You can edit any value if this is more convenient.

Next thing to do is to save all changes made in this section and do a little test to check if the code works well. You can enter a nonexistent URL on your blog, and see if the 404 error page added previously appears, followed by a redirection after 5 seconds. That's it!

How to make the background image of the blog fill the entire screen

A constant question is how to make the background image of the blog always fill the entire screen regardless of the resolution of the monitor. And that is when we put a background image as measured by our monitor forgetting that there are actually monitors of all resolutions, very small and very large. So if we put an image according to our screen, there will be someone with a bigger monitor that surely will not see the whole picture or it will be repeated, and in this case, using very small monitors, the image will be seen incomplete.

Here I will discuss two solutions to this, one using CSS3, and another with jQuery. With either of these two, we'll make the background image of the page to fill the entire screen regardless of the resolution of it.

CSS3

The first option is using CSS3, the advantage with this method is that we do not overload the blog with scripts, we use only the background-size property that is responsible for conducting what we want.
The disadvantage is that this property is supported only by modern browsers, so in the case of Internet Explorer, it will only be seen for version 9 and above, in other browsers there should be no problem.

The method is very simple, just go to Template - Edit HTML, locate the background that is within body { and replace it with this:

background: url(Image URL) no-repeat center center fixed;
background-size: cover;

It would look something like this:

body {
background: url(URL of the image) no-repeat center center fixed;
background-size: cover;
margin:0;
color:#000;
font:x-small Georgia Serif;
font-size/* */:/**/small;
font-size: /**/small;
text-align: center;
}

Just put the URL of the image and that's it.

jQuery

With this method we will use jQuery with BackStretch plugin, the advantage is that it works in all browsers, including IE7 and above. The disadvantage is not major if you already use jQuery, because the plugin is actually small.

To use this method in your blog, go to Template - Edit HTML and before </head> paste this script:

<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js' type='text/javascript'/>
<script type='text/javascript'>

;(function(a){a.backstretch=function(p,b,l){function s(){if(p){var b;0==c.length?c=a("<div />").attr("id","backstretch").css({left:0,top:0,position:m?"fixed":"absolute",overflow:"hidden",zIndex:-999999,margin:0,padding:0,height:"100%",width:"100%"}):c.find("img").addClass("deleteable");b=a("<img />").css({position:"absolute",display:"none",margin:0,padding:0,border:"none",zIndex:-999999,maxWidth:"none"}).bind("load",function(d){var b=a(this),e;b.css({width:"auto",height:"auto"});e=this.width||a(d.target).width();d=this.height||a(d.target).height();n=e/d;q();b.fadeIn(g.speed,function(){c.find(".deleteable").remove();"function"==typeof l&&l()})}).appendTo(c);0==a("body #backstretch").length&&(0===a(window).scrollTop()&&window.scrollTo(0,0),a("body").append(c));c.data("settings",g);b.attr("src",p);a(window).unbind("resize.backstretch").bind("resize.backstretch",function(){"onorientationchange"in window&&window.pageYOffset===0&&window.scrollTo(0,1);q()})}}function q(){try{j={left:0,top:0},rootWidth=h=o.width(),rootHeight=r?window.innerHeight:o.height(),f=h/n,f>=rootHeight?(k=(f-rootHeight)/2,g.centeredY&&(j.top="-"+k+"px")):(f=rootHeight,h=f*n,k=(h-rootWidth)/2,g.centeredX&&(j.left="-"+k+"px")),c.css({width:rootWidth,height:rootHeight}).find("img:not(.deleteable)").css({width:h,height:f}).css(j)}catch(a){}}var t={centeredX:!0,centeredY:!0,speed:0},c=a("#backstretch"),g=c.data("settings")||t;c.data("settings");var o,m,r,n,h,f,k,j;b&&"object"==typeof b&&a.extend(g,b);b&&"function"==typeof b&&(l=b);a(document).ready(function(){var b=window,d=navigator.userAgent,c=navigator.platform,e=d.match(/AppleWebKit\/([0-9]+)/),e=!!e&&e[1],f=d.match(/Fennec\/([0-9]+)/),f=!!f&&f[1],g=d.match(/Opera Mobi\/([0-9]+)/),h=!!g&&g[1],i=d.match(/MSIE ([0-9]+)/),i=!!i&&i[1];o=(m=!((-1<c.indexOf("iPhone")||-1<c.indexOf("iPad")||-1<c.indexOf("iPod"))&&e&&534>e||b.operamini&&"[object OperaMini]"==={}.toString.call(b.operamini)||g&&7458>h||-1<d.indexOf("Android")&&e&&533>e||f&&6>f||"palmGetResource"in window&&e&&534>e||-1<d.indexOf("MeeGo")&&-1<d.indexOf("NokiaBrowser/8.5.0")||i&&6>=i))?a(window):a(document);r=m&&window.innerHeight;s()});return this}})(jQuery);
//]]>
</script>
<script>
$.backstretch("URL of the image");
</script>

Put the URL of the image where indicated and ready.

As you can see both systems are easy to apply, each with its pros and cons, but the result is the same, extending the background image to fit the screen of any monitor regardless of the resolution of it.

Remember that in the case of jQuery method, you should verify that you are not using Mootools or Scriptaculous, if so you will have to implement some changes in the script to make it compatible.
And if you already use jQuery remember having only one version, the last one.

Making a gadget visible only to the blog administrator

And the post title says it all. There are gadgets that sometimes we want to be visible only to us and not to our blog readers, perhaps a Survey already ended that we want to keep, a counter, or any gadget that while we customize, we don't want anyone else to see until the final result is ready.

 The procedure is simple, we just have to add two lines to our gadget that we want to hide.

First thing to do is to go to Template > Edit HTML and then search for the gadget's code we want to hide. It will be easier using the CTRL + F keys and locating the name of the gadget/widget.

For example, in a HTML/Javascript gadget, we will see a code like this:

<b:widget id='HTML1' locked='false' title='' type='HTML'>
<b:includable id='main'>
<span class='item-control blog-admin'>
<!-- only display title if it's non-empty -->
<b:if cond='data:title != &quot;&quot;'>
<h2 class='title'><data:title/></h2>
</b:if>
<div class='widget-content'>
<data:content/>
</div>

<b:include name='quickedit'/>
</span>
</b:includable>
</b:widget>

All you have to do is add the parts in red and ready. If you close the session go to your blog you'll not be able to view the gadget that you have hidden, but as soon as you sign in you will see that it is visible to you.

Not all gadgets have the same structure like in my example, but it will be easier to guide you, just place the first code in red just after <b:includable id='main'>

And the second red code just before </b:includable>
Note: to look inside the widget's code, click on the sideways arrow next to the widget's id.

And with that the gadget will be hidden for readers except you.
