- Save time and Money: If you have a good knowledge of HTML and CSS then you wont have to depend on any web designer or developer to make changes in your blog design. You can simply edit CSS (Cascading Style Sheet) to change the look and feel of your blog.
- Adding features to your blog: Learning HTML can help you in adding features to your blog by adding widgets, Plugins and add-ons to your blog. HTML knowledge can also help you in changing the look and feel of your plugins and you can place them in your desired place of your blog page instead of placing where it's mentioned in the usual place as mentioned in the tutorial of the plugin.
- Making Money with your HTML and CSS skills: You can earn good money by editing and managing blogs for other bloggers who don't have HTML and CSS knowledge.
- Re-Designing your blog: I know redesigning the blog seems to be very big task but it's not really that scary as you think. You can simply edit your CSS and change the images and backgrounds of your blog to give your blog a new look and your HTML knowledge can help you in shuffling the widgets in your blog.
- Stress Free blogging: When you know you can manage your blog on your own without the help of any web designer that make you more indipendent and relaxed when you know that you wont have to spend a single penny to manage your blog, all you have to focus on is promoting your blog.
- Shaing the Knowledge: Create your own unique CSS styles and share that info on your blog that how you created that CSS and offer free download to your readers, this can really help build relation with your blog visitors.
- Create beautiful posts: You can show off your skills but putting your creativity in your blog posts, make your blog posts beautiful by adding something different in your post with the help of CSS and HTML. It's not something you have to do in your every posts but there are some posts which demand attention and then it's all up to your creativity what you do with your posts to beautify them.
I hope you will like this post. It was important for me to share this with post because I have seen many bloggers who spend hundreds of dollars on their blog just to make some slight changes in their blog. I myself have made changes to many blogs to help bloggers and also got paid for it nad you wont believe some of the tasks were only of 10-15mins and bloggers were offering $50-100 to make those changes to their blogs. So, now you know how important it is to learn HTML and CSS if you want to blog permanently without pissing of money.
